Experiencia con la herramienta ultrasonográfica Kosmos en el abordaje y tratamiento de pacientes de la consulta externa de insuficiencia cardiaca: un estudio transversal unicéntrico / Experience with the Kosmos ultrasonographic tool in the approach and treatment of ambulatory patients of a heart failure clinic: a single-center cross-sectional study

Resumen Antecedentes: En México aún es muy poco conocida la epidemiología de la insuficiencia cardiaca, sin embargo se sabe que la principal causa de ingresos hospitalarios en los pacientes con insuficiencia cardiaca es la congestión pulmonar y sistémica. Objetivo: Estimar el estado de congestión y evaluar la función cardiaca mediante el ultrasonido portátil en pacientes con insuficiencia cardiaca tratados en un centro de tercer nivel en México. Método: Se llevó a cabo un estudio observacional transversal. Se seleccionaron pacientes que acudieron a la Clínica de Insuficiencia Cardiaca del Instituto Nacional de Cardiología Ignacio Chávez en la Ciudad de México entre mayo y agosto de 2022. Se les sometió a una evaluación ultrasonográfica mediante un dispositivo portátil para valorar la congestión pulmonar y sistémica, así como la función y estructura cardiaca. Resultados: Se incluyeron de forma prospectiva 100 pacientes diagnosticados con insuficiencia cardiaca en el periodo de estudio. El 76% fueron hombres, con una edad mediana de 59 años (RIQ: 50-68 años). La mediana del FEVI registrada fue del 34% (RIQ: 27.0-43.5%). Al evaluar la congestión pulmonar, el 78% de los pacientes presentaron un patrón A y el 22% un patrón B. Siguiendo el protocolo VExUS, el 92% de los pacientes mostraron un grado 0, el 2% un grado 1 y el 6% un grado 2. Conclusiones: El uso del ultrasonido portátil facilitó la caracterización cuantitativa de las características ecocardiográficas de la población estudiada. Este dispositivo podría ofrecer una mejor caracterización clínica que, a su vez, permita una optimización en la prescripción de medicamentos para la insuficiencia cardiaca y el ajuste de dosis de diuréticos según los hallazgos ecocardiográficos de congestión.

Abstract Background: In Mexico, the epidemiology of heart failure is still not well understood. However, it is known that the primary cause of hospital admissions in patients with heart failure is pulmonary and systemic congestion. Objective: To estimate congestion status and assess cardiac function using portable ultrasound in patients with heart failure. Method: A cross-sectional observational study was conducted. Patients who attended the Heart Failure Clinic at the Ignacio Chávez National Cardiology Institute in Mexico City between May and August 2022 were selected. They underwent ultrasonographic evaluation using a portable device to assess pulmonary and systemic congestion, as well as cardiac function and structure. Results: One-hundred patients diagnosed with heart failure were prospectively included during the study period; 76% were male, with an average age of 59 years (range: 50-68 years). The recorded LVEF median was 34% (IQR: 27-43.5%). When evaluating pulmonary congestion, 78% of the patients showed a pattern A and 22% a pattern B. Following the VExUS protocol, 92% of the patients were at grade 0, 2% at grade 1, and 6% at grade 2. Conclusions: The use of the portable ultrasound facilitated the quantitative characterization of the echocardiographic features of the studied population. This device could provide better clinical characterization which, in turn, might allow for optimized drug prescription for heart failure and dose adjustments of diuretics based on echocardiographic congestion findings.

A Case of Three Directional Cuff Leakage from the Stent Posts of an Inspilis RESILIA Aortic Valve during Surgical Aortic Replacement / 日本心臓血管外科学会雑誌

We present the case of a 72-year-old male with Inspiris RESILIA aortic valve (Inspiris) transvalvular leakage during surgical aortic valve replacement (AVR). The patient initially underwent AVR for aortic regurgitation with a bicuspid aortic valve at the age of 64. By the age of 72, the valve had deteriorated and it was assessed that redoing the AVR was necessary. The Inspiris was inserted in the supra-annular position using the non-everting mattress suture technique with a COR-KNOT. During weaning off from cardiopulmonary bypass, transesophageal echocardiography (TEE) captured unfamiliar turbulent flows from the three stent posts. Further TEE revealed that these flows originated from the base of the stent posts, which gradually decreased and disappeared by the end of the surgery after administration of protamine. The patient has been discharged uneventfully. Paravalvular leakage has not been observed during the postoperative course and we could not find TVL in TEE 2 months postoperatively. While considering the detailed mechanism, it is possible that there is no need for re-exploration concerning three directional TVL in the Inspiris.

Assessment value of echocardiogram combined with serum hs-CRP and NT-proBNP levels on cardiac function of patients with coronary heart failure / 中国医学装备

Objective:To explore the assessment value of echocardiogram combined with serum high-sensitivity C-reactive protein(hs CRP)and N-terminal pro brain natriuretic peptide(NT proBNP)levels on cardiac function of patients with coronary heart failure.Methods:A total of 306 patients with coronary heart failure admitted to Beijing Daxing District People's Hospital from November 2021 to November 2022 were selected as the study group.Among of them,144 cases were grade Ⅱ,103 cases were grade Ⅲ and 59 cases were grade Ⅳ as the classification of New York Heart Association(NYHA)for cardiac function.A total of 108 healthy examinees who underwent physical examinations in our hospital during the same period were selected as the healthy control group.All examinees were classified as the NYHA for cardiac function,and left ventricular end diastolic volume(LVEDV),left ventricular end systolic volume(LVESV),left ventricular ejection fraction(LVEF),peak ejection rate(PER)and peak filling rate(PFR)of them were measured by echocardiogram.The NT proBNP and hs CRP levels of all examinees were measured.Receiver operating characteristic(ROC)curve was used to analyze the values of single LVEDV,LVESV,LVEF,PER,PFR,hs CRP and NT-proBNP,and the combination of them.Results:LVEDV(122.69±18.24)ml and LVESV(70.79±10.03)ml of the study group were significantly higher than(92.27±15.22)ml and(33.16±7.22)ml of the healthy control group,and the LVEF(42.26±5.13)％,PER(2.49±0.22)EDV/s and PFR(1.79±0.26)EDV/s of the study group were significantly lower than(69.34±5.27)％,(3.56±0.27)EDV/s,and(2.59±0.23)EDV/s of the healthy control group,with statistical significances(t=15.526,35.837,46.828,40.825,28.302,P<0.05),respectively.The levels of hs CRP and NT proBNP of the study group were significantly higher than those of the healthy control group,with statistical significance(t=88.000,29.099,P<0.05),respectively.The LVEDV and LVESV of grade Ⅱ/Ⅲ patients were significantly lower than those of grade Ⅳ patients,while LVEF,PER and PFR of grade Ⅱ/Ⅲ patients were significantly higher than those of grade Ⅳ patients,with statistically significant differences(t=53.391,92.658,32.140,240.474,116.921,P<0.05),respectively.The levels of hs CRP and NT proBNP of grade Ⅱ/Ⅲ patients were significantly lower than those in grade Ⅳ patients,with statistical significance(t=41.037,5.955,P<0.05),respectively.The results of ROC curve analysis showed that the sensitivities of single LVEDV,LVESV,LVEF,PER,PFR,hs CRP,NT proBNP and the combined examination of them were respectively 45.00％,50.00％,70.00％,70.00％,75.00％,70.00％and 90.00％,and the specificities of them were respectively 76.70％,57.00％,82.60％,44.20％,58.10％,52.30％and 96.50％.The area under curve(AUC)values of LVEDV,LVESV,LVEF,PER,PFR,hs CRP,NT proBNP and the combined examination of them were 0.592(95％CI:0.441-0.743),0.615(95％CI:0.468-0.761),0.766(95％CI:0.634-0.899),0.717(95％CI:0.575-0.860),0.674(95％CI:0.536-0.812),0.734(95％CI:0.592-0.876),0.581(95％CI:0.469-0.694)and 0.978(95％CI:0.947-1.000),respectively.Conclusion:The serum hs CRP,NT proBNP levels and function parameters of left heart in patients with coronary heart failure have occurred corresponding changes,and the above indicators have higher assessment value for the heart function of coronary heart failure,and the value of combined assessment is higher.

Anticoagulación precoz con warfarina en pacientes sometidos a sustitución valvular aórtica por bioprótesis: ensayo prospectivo randomizado: análisis interino / Early anticoagulation with warfarin in patients undergoing bioprosthetic aortic valve replacement: randomized prospective trial: interim analysis / Anticoagulação precoce com varfarina em pacientes submetidos à troca valvar aórtica por bioprótese: ensaio prospectivo randomizado: análise provisória

Introducción: aunque las bioprótesis son menos trombogénicas que las válvulas mecánicas; la trombosis de estas es una entidad cada vez más reconocida como causa de disfunción protésica potencialmente reversible. No está definido el beneficio de la anticoagulación rutinaria versus antiagregación plaquetaria luego de la sustitución valvular aórtica (SVA) por bioprótesis. La anticoagulación precoz podría asociarse a menores gradientes transprotésicos con similar riesgo de complicaciones. Objetivos: el objetivo primario es determinar si existe una diferencia significativa en la variación del gradiente transprotésico medio al año de la SVA entre las dos estrategias de tratamiento antitrombótico. Los objetivos secundarios son la comparación de la variación del gradiente máximo y del área valvular aórtica, y parámetros clínicos que incluyen la Clase Funcional de la New York Heart Association, las tasas de sangrado mayor y menor y la incidencia de eventos embólicos. Este trabajo representa el análisis interino a 3 meses de un proyecto a más largo plazo, y se propone mostrar los resultados preliminares de los puntos finales previamente definidos. Métodos: se presenta el análisis interino de un ensayo randomizado multicéntrico. Todos los pacientes sometidos a SVA por bioprótesis porcinas fueron sucesivamente reclutados en dos centros de cirugía cardíaca desde el 01/01/2019 hasta el 01/09/2019. El grupo anticoagulación recibió warfarina durante los primeros 3 meses y ambos recibieron aspirina a largo plazo. Se realizaron instancias de seguimiento clínicas y ecocardiográficas antes del alta, a los 3 meses y al año. Resultados: se reclutaron 107 pacientes; 46% de ellos fueron randomizados al grupo anticoagulación y 54% al grupo control. No existieron diferencias en las características basales. Tampoco existieron diferencias significativas entre ambos grupos en la variación entre el alta y los 3 meses del área valvular protésica, coeficiente de obstrucción, gradiente máximo ni gradiente medio ni en la clase funcional. En cuanto a las complicaciones, no existieron eventos embólicos y los sangrados no difirieron significativamente entre ambos grupos. Conclusiones: la anticoagulación no modificó la variación de los gradientes transprotésicos a los 3 meses. Asimismo, no produjo mayor incidencia de efectos adversos. Todavía no está dilucidado si la anticoagulación precoz con warfarina luego de la SVA tiene impacto en los resultados a largo plazo.

Introduction: although bioprostheses are less thrombogenic than mechanical valves, bioprosthesis valve thrombosis is an increasingly recognized entity that can cause potentially reversible prosthetic valve dysfunction. There is a lack of consensus whether to use anticoagulation after aortic valve replacement (AVR) or antiplatelet therapy. Our hypothesis is that early anticoagulation is associated with lower transprosthetic gradients with similar risk of complications. Objective: primary objective is to determine if there is a significant difference in the variation of the mean transprosthetic gradient (ΔGm) one year after SVA between the two antithrombotic treatment strategies. Secondary objectives are the comparison of the variation of maximum gradient and aortic valve area, and clinical parameters including NYHA functional class, major and minor bleeding rates, and the incidence of embolic events. This work represents the 3-month interim analysis of a longer-term project, and is intended to show the preliminary results of the previously defined end points. Methods: this is an interim analysis of a multicenter randomized trial. All patients who underwent AVR by porcine bioprostheses were successively recruited in two cardiac surgery centers in Montevideo between 01/01/2019 and 01/09/2019. The anticoagulation group received warfarin for 3 months. Both groups received aspirin. Clinical and echocardiographic follow-up consultations were performed before discharge, at 3 months, and at 1 year. Results: 107 patients were recruited, 46% were randomized to the anticoagulation group and 54% to the control group. There were no differences in baseline characteristics. There were no significant differences between the two groups in the variation between discharge and 3 months of effective orifice area, doppler velocity index, peak gradient and mean gradient. There were also no differences between both groups in functional class. Regarding complications, there were no embolic events and bleeding did not differ significantly. Conclusions: in this study, anticoagulation did not modify the variation of transprosthetic gradients at 3 months. Likewise, it did not produce a higher incidence of adverse effects. It remains unclear whether early anticoagulation with warfarin after AVR has an impact on long-term outcomes.

Introdução: embora as biopróteses sejam menos trombogênicas que as mecânicas, a trombose de biopróteses é uma entidade cada vez mais reconhecida como causa de disfunção protética potencialmente reversível. A anticoagulação de rotina após a substituição da valva aórtica por bioprótese (SVA) não está definida. Nossa hipótese é que a anticoagulação precoce está associada a menores gradientes transprotéticos com risco semelhante de complicações. Objetivo: o objetivo principal é determinar se há uma diferença significativa na variação do gradiente transprotético médio (ΔGm) um ano após SVA entre as duas estratégias de tratamento antitrombótico. Os objetivos secundários são a comparação da variação do gradiente máximo e da área valvar aórtica e parâmetros clínicos, incluindo NYHA CF, taxas de sangramento maior e menor e incidência de eventos embólicos. Este trabalho representa a análise intercalar de 3 meses de um projeto de longo prazo, e pretende mostrar os resultados preliminares dos pontos finais previamente definidos. Métodos: apresenta-se a análise interina de um estudo multicêntrico randomizado. Todos os pacientes submetidos a SVA por biopróteses suínas foram sucessivamente recrutados em dois centros de cirurgia cardíaca em Montevidéu, durante um período de recrutamento de 1/1/2019 a 1/9/2019. O grupo de anticoagulação recebeu warfarina por 3 meses. Ambos os grupos receberam aspirina. Foram realizadas consultas médicas clínicas e ecocardiográficas antes da alta, aos 3 meses e ao 1 ano. Resultados: foram recrutados 107 pacientes, 46% foram randomizados para o grupo anticoagulação e 54% para o grupo controle. Não houve diferenças nas características basais. Não houve diferenças significativas entre os dois grupos da variação entre alta e 3 meses na área valvar, coeficiente de obstrução, gradiente máximo ou gradiente médio. Também não houve diferenças entre os dois grupos na classe funcional. Em relação às complicações, não houve eventos embólicos e sangramentos não diferiram significativamente. Conclusões: neste estudo, a anticoagulação não modificou a variação dos gradientes transprotéticos aos 3 meses. Da mesma forma, não produziu maior incidência de efeitos adversos. Ainda não está claro se a anticoagulação precoce com varfarina após SVA tem impacto nos resultados a longo prazo.

Endocarditis Infecciosa Mural Apical del Ventrículo Izquierdo: Presentación de caso clínico y revisión bibliográfica / Infectious Apical Mural Endocarditis of the Left Ventricle: Clinical case presentation and bibliographic review

RESUMEN La endocarditis mural es una forma infrecuente de infección intracardiaca que afecta al endocardio no valvular que pue- de presentarse con complicaciones similares a la endocarditis infecciosa valvular. Se recomienda la ecocardiografía para confirmar el diagnóstico cuando exista un alto índice de sospecha. Con respecto al tratamiento, existe evidencia limitada acerca de las estrategias terapéuticas en la endocarditis mural, sin embargo en la mayoría de casos reportados se recomienda iniciar antibioticoterapia dirigida asociado a una intervención quirúrgica precoz. A continuación, se presenta un caso clínico de un paciente masculino de 74 años con fenómenos embólicos sistémicos, en quien se documenta por ecocardiograma transesofágico una endocarditis mural en ápex del ventrículo izquierdo asociado a una bacteriemia por Staphylococcus aureus. Este caso pone de manifiesto la importancia de una valoración ecocardiográfica detallada de las válvulas y cámaras cardíacas ante la sospecha de una endocarditis infecciosa.

ABSTRACT Mural endocarditis is an uncommon form of intracardiac infection affecting the non valvular endocardium that can present with complications similar to valvular infective endocarditis. Echocardiography is recommended to confirm the diagnosis when there is a high index of suspicion. Regarding treatment, there is limited evidence about therapeutic strategies in mural endocarditis, however in most reported cases it is recommended to initiate targeted antibiotic therapy associated with early surgical intervention. The following is a clinical case of a 74-year-old male patient with systemic embolic phenomena, in whom a transesophageal echocardiogram documented mural endocarditis in the apex of the left ventricle associated with Staphylococcus aureus bacteremia. This case highlights the importance of a detailed echocardiographic assessment of the cardiac valves and chambers when infective endocarditis is suspected.

Multiparameters Associated to Successful Weaning from VA ECMO in Adult Patients with Cardiogenic Shock or Cardiac Arrest: Systematic Review and Meta?Analysis

Venoarterial extracorporeal membrane oxygenation (VA ECMO) is a form of temporary mechanical circulatory support and simultaneous extracorporeal gas exchange for acute cardiorespiratory failure, including refractory cardiogenic shock (CS) and cardiac arrest (CA). Few studies have assessed predictors of successful weaning (SW) from VA ECMO. This systematic review and meta-analysis aimed to identify a multiparameter strategy associated with SW from VA ECMO. PubMed and the Cochrane Library and the International Clinical Trials Registry Platform were searched. Studies reporting adult patients with CS or CA treated with VA ECMO published from the year 2000 onwards were included. Primary outcomes were hemodynamic, laboratory, and echocardiography parameters associated with a VA ECMO SW. A total of 11 studies (n=653) were included in this review. Pooled VA ECMO SW was 45% (95%CI: 39�%, I2 7%) and in?hospital mortality rate was 46.6% (95%CI: 33�%; I2 36%). In the SW group, pulse pressure [MD 12.7 (95%CI: 7.3�) I2 = 0%] and mean blood pressure [MD 20.15 (95%CI: 13.8�.4 I2 = 0) were higher. They also had lower values of creatinine [MD �59 (95%CI: �9 to �2) I2 = 7%], lactate [MD �1 (95%CI: �4 to �7) I2 = 89%], and creatine kinase [�79.5 (95%CI: �87 to �1) I2 = 38%]. And higher left and right ventricular ejection fraction, MD 17.9% (95%CI: �2�.2) I2 = 91%, and MD 15.9% (95%CI 11.9�) I2 = 0%, respectively. Different hemodynamic, laboratory, and echocardiographic parameters were associated with successful device removal. This systematic review demonstrated the relationship of multiparametric assessment on VA ECMO SW.

Comparative study between suprasternal and apical windows: a user-friendly cardiac output measurement for the anesthesiologist

Abstract Introduction Transthoracic echocardiography is a safe and readily available tool for noninvasive monitoring of Cardiac Output (CO). The use of the suprasternal window situated at the sternal notch can be an alternative approach for estimating blood flow. The present study aimed to compare two methods of CO calculation. We compared the descending aorta Velocity-Time Integral (VTI) measurement from the suprasternal window view with the standard technique to determine CO that uses VTI measurements from the LVOT (Left Ventricular Outflow Tract) view. We also aimed to find out whether after basic training a non-echocardiographer operator can obtain reproducible measurements of VTI using this approach. Methods In the first part of the study, 26 patients without known cardiovascular diseases were evaluated and VTI data were acquired from the suprasternal window by a non-echocardiographer and an echocardiographer. Next, 17 patients were evaluated by an echocardiographer only and VTI and CO measurements were obtained from suprasternal and apical windows. Data were analyzed using the Bland and Altman method (BA), correlation and regression. Results We found a strong correlation between measurements obtained by a non-expert and an expert echocardiographer and detected that an inexperienced trainee can acquire VTI measurements from the suprasternal window view. Regarding agreement between CO measurements, data obtained showed a positive correlation and the Bland and Altman analysis presented a total variation of 38.9%. Conclusion Regarding accuracy, it is likely that TTE (Transthoracic Echocardiogram) measurements of CO from the suprasternal window view are comparable to other minimally invasive techniques currently available. Due to its user-friendliness and low cost, it can be a convenient technique for obtaining perioperative hemodynamic measurements, even by inexperienced operators.

Prevalence of subclinical systolic dysfunction in Takayasu's arteritis and its association with disease activity: a cross-sectional study

Abstract Background Takayasu's arteritis (TA) is a vasculitis that affects the aorta and its branches and causes stenosis, occlusion, and aneurysms. Up to 60% of TA patients are associated with cardiac involvement which confers a poor prognosis. Global longitudinal strain (GLS) analysis is an echocardiographic technique that can detect the presence of subclinical systolic dysfunction. Hence, this study aimed to describe the prevalence of subclinical systolic dysfunction in patients with TA using the GLS method and to correlate this finding with disease activity using the ITAS-2010 (Indian Takayasu Activity Score). Methods Thirty patients over 18 years of age who met the American College of Rheumatology (ACR) 1990 criteria for TA were included. The sample was submitted for medical record review, clinical and echocardiographic evaluation, and application of ITAS-2010. The cutoff for systolic dysfunction was GLS > - 20%. Results Of the 30 patients analyzed, 25 (83.3%) were female, and the mean age was 42.6 years (± 13.2). The median time since diagnosis was 7.5 years [range, 3-16.6 years], and the type V angiographic classification was the most prevalent (56.7%). Regarding echocardiographic findings, the median ejection fraction (EF) was 66% [61-71%] and the GLS was - 19.5% [-21.3 to -15.8%]. Although half of the participants had reduced GLS, only two had reduced EF. Eleven patients (33.%) met the criteria for activity. An association was found between disease activity and reduced GLS in eight patients (P = 0.02) using the chi-square test. Conclusion GLS seems to be an instrument capable of the early detection of systolic dysfunction in TA. The association between GLS and disease activity in this study should be confirmed in a study with a larger sample size.

Trombo en tránsito entre la aurícula derecha y la vena cava inferior en un paciente con contraindicación absoluta para trombólisis / Thrombus in transit between the right atrium and the inferior vena cava in a patient with an absolute contraindication for thrombolysis

Resumen La tromboembolia venosa es una condición relativamente común que se identifica en los servicios de urgencias y que representa morbilidad y mortalidad significativas en la población. Su desenlace más grave es la tromboembolia pulmonar, la cual desencadena una serie de procesos fisiopatológicos que pueden terminar en paro cardiaco y en la muerte posterior del paciente. Un trombo en las cavidades cardiacas derechas o en la vena cava es poco detectable; esta condición se conoce en la literatura como trombo en tránsito, y su hallazgo se asocia con alta mortalidad hospitalaria. A continuación, se presenta el caso de un paciente de sexo femenino, de 64 años de edad, con antecedente de cáncer uterino activo, hospitalizada por trombosis venosa profunda y en quien se tomó un ecocardiograma transtorácico de control que mostró un trombo en tránsito de alta movilidad en el límite entre la aurícula derecha y la vena cava inferior.

Abstract Venous thromboembolism is a relatively common condition that is identified in the emergency services and represents significant morbidity and mortality in the population. Its most severe outcome is pulmonary thromboembolism, which triggers several pathophysiological processes that can end in cardiac arrest and subsequent death of the patient. A thrombus found in the right cavities or in the vena cava is an undetectable process, this condition is known like ongoing thrombus. The finding of thrombus in transit has been associated with high hospital mortality. We present the case of a 64-year-old female patient with a history of active uterine cancer, who was hospitalized for deep vein thrombosis and in whom a control transthoracic echocardiogram is taken, showing evidence of a highly mobile thrombus in transit between the right atrium and inferior vena cava compatible with ongoing thrombus at this level.

Insuficiencia cardíaca de novo: Un reto diagnóstico / Di novo heart failure: A diagnostic challenge

Introducción: El término insuficiencia cardíaca de novo hace referencia a pacientes sin diagnóstico previo de dicha enfermedad. La revisión de este tema deviene de un problema real, pues muchos pacientes acuden a la atención secundaria sin diagnóstico previo de insuficiencia cardíaca y además en estadios avanzados. Objetivo: Describir los elementos claves para el diagnóstico precoz de insuficiencia Cardíacas. Métodos: Se llevó a cabo una búsqueda bibliográfica en las siguientes bases de datos: Pubmed, SciELO, ESBCO, Cochrane y BVS, así como en diferentes webs médicas durante tres meses entre febrero de 2021 al 31 de mayo de 2021. Conclusiones: El diagnóstico precoz de insuficiencia cardíaca permitió disminuir el número de pacientes que llegan a la Atención Secundaria sin diagnóstico previo. Existen clasificaciones que identifican estadios tempranos de la enfermedad y la de la ACC/AHA es relevante para lograr este objetivo. En atención primaria esto es un reto si no se emplean pruebas diagnósticas como el ecocardiograma. Es importante la determinación de las concentraciones circulantes del péptido natriurético tipo B (BNP) y del fragmento N-terminal de su protohormona (N-terminal BNP). Este biomarcador debería estar accesible en las consultas ambulatorias para pacientes que presentan sospecha clínica de insuficiencia cardíaca «de novo»(AU)

Introduction: The term di novo heart failure refers to patients without a previous diagnosis of this disease. The review of this issue comes from a real problem, since a group of patients attend secondary care without a previous diagnosis of heart failure and also have in advanced stages. Objective: The objective is to provide a clue that facilitates the early diagnosis of heart failure. Methods: A bibliographic search was carried out in the following databases: Pubmed, SciELO, ESBCO, Cochrane and BVS, as well as in different medical websites for three months (February 1, 2021 to May 31, 2021). Conclusions: The early diagnosis of heart failure will allow us to reduce the number of patients who arrive at Secondary Care without a previous diagnosis. There are classifications that identify early stages of the disease, being in our opinion the ACC / AHA classification the one that should carry the most weight. In primary care this can be a challenge if diagnostic tests such as echocardiography are not used. Dosification of serum levels of type B natriuretic peptide (BNP) and the N-terminal fragment of its protohormone (N-terminal BNP) is very useful. This biomarker should be accessible in outpatient clinics for patients with clinical suspicion of di novo heart failure(AU)

Prevalence of Cardiotoxicity Induced by Chemotherapy Measured by Dobutamine Stress Echocardiogram (DSE) in BSMMU

Background: Cardiotoxicity related to cancer treatment is an alarming source of significant morbidity and mortality, and may differ from subclinical myocardial dysfunction to irreversible heart failure or even death. DSE is a safe, feasible, and accurate modality for finding of myocardial ischemia and prognostication in patients with known or suspected coronary artery disease, particularly when they have limited exercise capacity.Materials& Methods:This study is a cross-sectional observational study which was conducted at the department of Cardiology, in BSMMU, Dhaka from June 2019- December 2019. The sample size for this study was 50.Results:The mean age was 56� where 17(34%) of the respondents were <65 years and 33(66%) were >65 years. The male respondent was 35(70%) where female was 15(30%). Diabetes was found in 3(6%) cases and followed by Acute ischemia, Hypertension 6(12%), Coronary Artery Disease (CAD) 4(8%), ACE-inhibitors 5(10%), Beta-blockers 3(6%), Nitrates 3(6%). Acute leukemia was found in 13(26%). in M12-18 was 45�and followed by mean of LVESD (mm) was 27� 29� 29� 30� 30� 31� Mean of IVSd (mm) was 9� 9� 9� 9� 8� 8� Mean of Peak E (cm/s) was 80�, 76�, 74�, 73�, 66� 63� and the p-value was seen <0.001 which denotes a significant improvement in treatment (p<0.005).Conclusions:The early discovery of cardiotoxicity may ensure the improved chemotherapeutic process and timely management of the treatment of cardiomyopathy, such as beta-blockers and ACE inhibitors.

A Curva Volume-Tempo Obtida pela Ecocardiografia Tridimensional na Cardiomiopatia Chagásica: Análise do Mecanismo das Adaptações Hemodinâmicas / The Volume-Time Curve by Three-Dimensional Echocardiography in Chagas Cardiomyopathy: Insights into the Mechanism of Hemodynamic Adaptations

Resumo Fundamento A ecocardiografia tridimensional (ECO 3D) permite a geração de uma curva volume-tempo representativa das alterações no volume ventricular esquerdo (VE) ao longo de todo o ciclo cardíaco. Objetivo O presente estudo tem como objetivo demonstrar as adaptações hemodinâmicas presentes na cardiomiopatia chagásica (CC) por meio das medidas de volume e fluxo obtidas pela curva volume-tempo por ECO 3D. Métodos Vinte pacientes com CC e 15 indivíduos saudáveis foram incluídos prospectivamente em um estudo de desenho transversal. Realizou-se ECO 3D em todos os indivíduos e as curvas volume-tempo do VE foram geradas. O fluxo foi obtido pela primeira derivada da curva volume-tempo por meio do software MATLAB. A significância estatística foi definida com p<0,05. Resultados Embora os pacientes com CC tivessem menor fração de ejeção do VE em comparação com o grupo controle (29,8±7,5 vs. 57,7±6,1, p<0,001), o volume (61,5±25,2 vs. 53,8±21,0, p=0,364) e o fluxo de ejeção máximo durante a sístole (-360,3±147,5 vs. -305,6±126,0, p = 0,231) mostraram-se semelhantes entre os grupos. Da mesma forma, o fluxo máximo na fase de enchimento inicial e durante a contração atrial mostrou-se semelhante entre os grupos. Um aumento na pré-carga expressa pelo volume diastólico final do VE (204,8±79,4 vs. 93,0±32,6), p<0,001) pode manter o fluxo e o volume ejetado semelhantes aos dos controles. Conclusão Com uma ferramenta não invasiva, demonstramos que o aumento no volume diastólico final do VE pode ser o principal mecanismo de adaptação que mantém o fluxo e o volume ejetado no cenário de disfunção sistólica ventricular esquerda severa.

Abstract Background Three-dimensional echocardiography (3D ECHO) allows the generation of a volume-time curve representative of changes in the left ventricular (LV) volume throughout the entire cardiac cycle. Objective This study aims to demonstrate the hemodynamic adaptations present in Chagas cardiomyopathy (CC) by means of the volume and flow measurements obtained by the volume-time curve by 3D ECHO. Methods Twenty patients with CC and 15 healthy subjects were prospectively enrolled in a cross-sectional design study. 3D ECHO was performed in all subjects and the volume over time curves of the LV was generated. The flow was obtained by the first derivative of the volume-time curve using the software MATLAB. Statistical significance was set at p<0.05. Results Although CC patients had lower LV ejection fraction compared to the control group (29.8±7.5 vs. 57.7±6.1, p<0.001), stroke volume (61.5±25.2 vs. 53.8±21.0, p=0.364) and maximum ejection flow during systole (-360.3±147.5 vs. -305.6±126.0, p=0.231) were similar between the groups. Likewise, the maximum flow in the early diastolic filling phase and during atrial contraction was similar between groups. An increase in preload expressed by LV end diastolic volume (204.8±79.4 vs. 93.0±32.6), p<0.001) may maintain the flow and stroke volumes similar to the controls. Conclusion Using a non-invasive tool, we demonstrated that an increase in LV end-diastolic volume may be the main adaptation mechanism that maintains the flow and stroke volumes in the setting of severe LV systolic dysfunction.

Rare Case of Sars COV2 Virus (COVID 19) Associated Intra Myocardial Hematoma and Role of Diagnostic Imaging

SARS Cov2 infection is a pandemic declared by WHO in early month of 2020 as corona virus disease (COVID 19) which was diagnosed first in Wuhan, China in December 2019. During first wave of COVID 19 we faced with severe acute respiratory insufficiency and respiratory failure with common symptoms of high-grade fever, shortness of breath and loss of sensations but later on we accessed the different symptoms to related with multi systems of human body. Cardiac emergencies or cardiovascular morbidities with mortality were accessed across the globe during COVID 19 pandemic era. Data revealed that SARS Cov2 affected on heart by both direct or indirect pathway which leads to acute myocarditis, myocardial injury/infarct, heart failure, thrombosis and arrhythmias. Here we are presenting a rare case as hematoma in myocardium called as intramyocardial dissecting hematoma. Non-invasive diagnostic tools to prevent mortality in cardiology field and avoid further complication.

Desempeño del método de suma de discos comparado con el método bidimensional en la estimación cuantitativa del derrame pericárdico / Performance of the method of disks compared to the bidimensional method in the quantitative estimation of pericardial effusion

Resumen Introducción: La ecocardiografía bidimensional es la técnica más efectiva para el diagnóstico del derrame pericárdico, gracias a sus altas sensibilidad y especificidad. Objetivo: Analizar la superioridad del método de suma de discos comparado con el método bidimensional en la estimación del derrame pericárdico por medio de ecocardiografía, tomando como referencia el volumen de líquido pericárdico extraído por pericardiocentesis o cirugía abierta. Método: Estudio retrospectivo de seguimiento de una cohorte basado en registros médicos y archivos de ecocardiografía. Se empleó un diseño pareado en el que cada imagen fue leída por el método bidimensional y por el método de suma de discos. Se incluyeron derrames pericárdicos graves, definidos clínicamente o por parámetros ecocardiográficos, que requirieran drenaje. El desempeño de los métodos de estimación bidimensional y de suma de discos, tomando como referencia la extracción por intervención, se cuantificó mediante áreas bajo la curva operador-receptor (auROC). Resultados: Se analizaron 40 registros, tomando como referencia el volumen obtenido por extracción; con un auROC de 0.81 (intervalo de confianza del 95% [IC95%]: 0.73-0.89), el desempeño diagnóstico del método de suma de discos fue significativamente mayor (p = 0.0335) que el del método bidimensional (auROC: 0.73; IC95%: 0.63-0.83). La estimación realizada por el método de suma de discos subestimó en promedio 51.3 ml (IC95%: −156.2-53.5). Conclusiones: En pacientes con derrame pericárdico e indicación de drenaje o taponamiento cardíaco, el método de suma de discos es superior en comparación con el método bidimensional en el estudio ecocardiográfico para la estimación cuantitativa del derrame pericárdico, ya que discrimina mejor respecto al método bidimensional.

Abstract Introduction: Two-dimensional echocardiography is the most effective technique for diagnosing pericardial effusion due to its high sensitivity and specificity. Objective: The superiority of the method of disks was compared with the bidimensional method in the estimation of pericardial effusion by echocardiography, taking as reference the volume of pericardial fluid removed by pericardiocentesis or open surgery. Method: Retrospective follow-up study of a cohort, based on medical records and echocardiography files. A paired design was used, each image was read by the bidimensional method and by the method of disks. Severe pericardial effusions defined clinically or by echocardiographic parameters, that required drainage were included. The performance of the bidimensional and disks estimation methods, taking the volume removed as a reference, was quantified using areas under the receiver operating characteristic curve (auROC). Results: 40 records were analyzed, taking as a reference the volume obtained by extraction, with an auROC of 0.81 (95% CI: 0.73-0.89) the diagnostic performance of the disks method was significantly higher (p = 0.0335) than the bidimensional method (auROC 0.73, 95% CI: 0.63-0.83). The estimate made by the disks method underestimated an average of 51.3 ml (95% CI: -156.2-53.5). Conclusions: In patients with pericardial effusion with indication of cardiac drainage or tamponade, the disks method is superior in comparison with the bidimensional method in the echocardiographic study of the quantitative estimation of pericardial effusion, discriminating better than the bidimensional method.

Application of 3.0 T non-contrast coronary MR angiography in children with Kawasaki disease / 中华放射学杂志

Objective:To explore the diagnostic accuracy and application value of 3.0 T non-contrast coronary magnetic resonance angiography (CMRA) in evaluating coronary artery in children with Kawasaki disease (KD).Methods:From May 2019 to January 2022, 75 children diagnosed with KD in our hospital were enrolled. All the patients underwent CMRA and transthoracic echocardiography (TTE) in one week, twenty-six of whom underwent coronary CT angiography (CCTA) or invasive coronary angiography (ICA) within two weeks. The diagnostic performance of CMRA and TTE was evaluated with CCTA/ICA as reference standard by per-patient basis, per-vessel basis, per-segment basis. Sensitivity and specificity of CMRA and TTE was compared by paired chi square test.The distribution of coronary artery aneurysm (CAA), thrombosis and other pathological changes of coronary artery were recorded and compared between two methods. The patients′ height and weight were collected to calculate the Z value. Z value>2.5 was defined as CAA.Results:All patients successfully completed CMRA examinations. Among the 26 patients, the sensitivity of CMRA was significantly higher than that of TTE by per coronary artery[97.7%(43/44)vs.84.1%(37/44), χ2=4.17, P<0.05]. CMRA showed a higher sensitivity than that of TTE both by proximal segments and middle/distal segments [97.7%(43/44)vs. 84.1%(37/44), 100%(21/21) vs. 52.4%(11/21), χ2=10.08, 7.11, both P<0.05). A total of 115 CAAs was found by CMRA, while only 87 (75.7%) CAAs were observed by TTE. Of the 28 (24.3%) CAAs missed by TTE, 16 (57.1%) were located in right coronary artery (RCA), 2(7.1%) in left main coronary artery, 7(25.0%) in left anterior ascending coronary artery (LAD) and 3(10.7%) in left circumflex coronary artery (LCX). Eleven (39.3%) missed CAAs by TTE were located in the proximal segment of RCA, LMCA, LAD and LCX, and 17 (60.7%) missed CAAs were located in the middle and distal segments. TTE missed coronary thrombosis in 5 patients compared with CMRA. Conclusions:3.0 T non-contrast CMRA is non-invasive and non-radiation, and the image quality can meet the needs of diagnosis, especially for detection of CAAs in RCA or in middle and distal segments of coronary artery in KD patients.

Diagnostic value of echocardiogram and cardiac magnetic resonance imaging for hypertrophic cardiomyopathy / 中国辐射卫生

Objective To compare echocardiogram and cardiac magnetic resonance imaging (MRI) for diagnosis of hypertrophic cardiomyopathy. Methods A total of 137 patients suspected of hypertrophic cardiomyopathy were recruited. All patients received three-dimensional echocardiogram followed by cardiac MRI, and the detection rate of hypertrophic cardiomyopathy was compared. Results A total of 96 eligible patients with hypertrophic cardiomyopathy were finally enrolledin this study, including 70 males (72.9%) and 26 females (27.1%), with a mean age of 48.2 ± 10.2 years. There was a significant difference in the detection rate of hypertrophic cardiomyopathy by echocardiogram (93.8%) and by cardiac MRI (100%) (χ2 = 4.30, P = 0.03). Among the 96 subjects, there was no significant difference in the mean value of maximum left ventricular wall thickness measured by echocardiogram and cardiac MRI (22.1 ± 8.9 vs 22.8 ± 9.2 mm; t = 1.23, P = 0.32). There was a significant difference in the mean thickness of the basal anterolateral free wall in the left ventricle (18.2 ± 7.8 vs 13.9 ± 7.1 mm; t = 9.40, P = 0.0007). Conclusion Cardiac MRI scanning is superior to echocardiogram for diagnosis of hypertrophic cardiomyopathy, which may be used as an effective supplement to conventional echocardiogram.

Strain longitudinal global como preditor de cardiotoxicidade induzida por quimioterapia / Global longitudinal strain as predictor of chemotherapy-induced cardiotoxicity

Fundamento: A cardiotoxicidade induzida por quimioterapia (CiC) é uma complicação importante entre os pacientes que recebem antraciclinas. Biomarcadores e parâmetros de imagem têm sido estudados por sua capacidade de identificar pacientes com risco de desenvolver essa complicação. O strain longitudinal global do ventrículo esquerdo (SLG-VE) tem sido descrito como um parâmetro sensível para detectar disfunção sistólica, mesmo na presença de fração de ejeção do ventrículo esquerdo (FEVE) preservada. Objetivo: avaliar o papel do SLG-VE como preditor de CiC. Métodos: O presente estudo consiste em uma análise post-hoc do estudo CECCY (Carvedilol for Prevention of ChemotherapyRelated Cardiotoxicity [Carvedilol para Prevenção da Cardiotoxicidade Relacionada à Quimioterapia]), que avaliou a prevenção primária de cardiotoxicidade com carvedilol durante quimioterapia com doxorrubicina em uma população com câncer de mama. Definiu-se cardiotoxicidade como uma redução >10% na FEVE. O SLG-VE foi obtido antes da quimioterapia em pacientes sem doença cardiovascular prévia ou anormalidades no ecocardiograma. Resultados: Trinta e um pacientes submetidos a estudo ecocardiográfico completo incluindo avaliação de SLG-VE antes da quimioterapia foram incluídos nesta análise. Um SLG-VE absoluto <16,9% antes da quimioterapia mostrou 100% de sensibilidade e 73% de especificidade para predizer cardiotoxicidade (AUC=0,85; IC 95% 0,680­0,959, p<0,001). Nesta população, os valores de FEVE antes da quimioterapia não foram preditores de CiC (IC 95% 0,478 a -0,842, p=0,17). A associação de baixos níveis séricos de SLG-VE (<17%) e BNP (>17 pg/mL) dois meses após a quimioterapia aumentou a precisão para detectar CiC de início precoce (100% de sensibilidade, 88% de especificidade, AUC=0,94; IC 95% 0,7810,995, p<0,0001). Conclusões: Nossos dados sugerem que o SLG-VE é um possível preditor de cardiotoxicidade induzida por quimioterapia. São necessários estudos maiores para confirmar a relevância clínica desse parâmetro ecocardiográfico nesse cenário clínico. (AU)

Background: Chemotherapy-induced cardiotoxicity (ChC) is an important complication among patients receiving anthracyclines. Biomarkers and imaging parameters have been studied for their ability to identify patients at risk of developing ChC. Left ventricular global longitudinal strain (LV-GLS) is a sensitive parameter for detecting systolic dysfunction despite the presence of preserved left ventricular ejection fraction (LVEF). Objective: To evaluate the role of the LV-GLS as a predictor of ChC. Methods: This was a post-hoc analysis of the Carvedilol for Prevention of Chemotherapy-Related Cardiotoxicity trial, which evaluated the primary prevention of cardiotoxicity with carvedilol during doxorubicin chemotherapy in a population of patients with breast cancer. Cardiotoxicity was defined as a reduction ≥10% in LVEF. LV-GLS was determined before chemotherapy in patients with no prior cardiovascular disease or echocardiogram abnormalities. Results: Thirty-one patients for whom a complete echocardiography study including measurement of LV-GLS was performed before chemotherapy were included in this analysis. An absolute LV-GLS<16.9% before chemotherapy showed 100% sensitivity and 73% specificity for predicting cardiotoxicity (area under the curve [AUC], 0.85; 95% confidence interval [CI], 0.680­0.959; p<0.001). In this population, LVEF values before chemotherapy did not predict ChC (95% CI, 0.478 to -0.842; p=0.17). The association of low LV-GLS (<17%) and brain-type natriuretic peptide serum levels (>17 pg/mL) at 2 months after chemotherapy increased the accuracy for detecting early-onset ChC (100% sensitivity, 88% specificity; AUC, 0.94; 95% CI, 0.781­0.995; p<0.0001). Conclusions: Our data suggest that LV-GLS is a potential predictor of ChC. Larger studies are needed to confirm its clinical relevance in this clinical setting. (AU)

Segurança do Agente de Contraste SF6 (SonoVueⓇ) no Ecocardiograma sob Estresse Farmacológico / Safety of SF6(SonoVue®) Contrast Agent on Pharmacological Stress Echocardiogram

Resumo Fundamento Em 2007, a Food and Drug Administration (FDA) determinou revisões sobre segurança dos agentes de contraste ecocardiográfico (ACE) disponíveis no mercado após relatos de mortes. Ao longo desses anos, diversos estudos comprovaram a segurança dos ACE, porém com poucos estudos relacionados ao SonoVue®. Objetivos Avaliar a segurança do SonoVue® durante o ecocardiograma sob estresse farmacológico (EEF) por meio da análise da incidência de reações alérgicas e da comparação entre os grupos quanto ao surgimento de arritmia, efeitos colaterais menores e eventos adversos. Métodos Estudo observacional, prospectivo, no qual 2.346 pacientes foram submetidos ao EEF e divididos em dois grupos: grupo 1 com ACE (n=1.099) e grupo 2 sem ACE (n=1.247). Os pacientes foram avaliados durante o EEF - 24 horas e 30 dias. Foi definido p significativo quando <0,05. Resultados O grupo 1 apresentou efeitos colaterais mais leves, como cefaleia (5/0,5% vs. 19/1,5%, p=0,012) e hipertensão reativa (3/0,3% vs . 19/1,5%, p=0,002), menos arritmias como extrassístoles ventriculares (180/16,4% vs . 247/19,8%, p=0,032) e taquicardia paroxística supraventricular (2/0,2% vs . 15/1,2%, p=0,003), assim como nenhum evento adverso como infarto agudo do miocárdio (IAM) e óbito. No grupo 2, um paciente apresentou IAM <24h (1/01%) e dois óbitos <30 dias (2/0,1%). Urticária relacionada ao SonoVue® foi observada em 3 (0,3%) pacientes sem reação anafilática. Conclusão SonoVue® demonstrou segurança durante o EEF, não sendo observados morte, IAM ou reação anafilática. Observou-se menor incidência de efeitos colaterais mais leves e arritmias no grupo que utilizou o ACE, assim como baixa incidência de reações alérgicas leves.

Abstract Background In 2007, the United States Food and Drug Administration mandated safety reviews of commercially available echocardiographic contrast agents (ECA), following reports of death. During the past years, different studies have proven the safety of ECA, but there have been few studies on SonoVue®. Objectives To evaluate the safety of SonoVue® during pharmacological stress echocardiography (PSE), by analyzing the incidence of allergic reactions and comparing groups regarding the appearance of arrhythmia, minor side effects and adverse events. Methods In this observational, prospective study, 2346 patients underwent PSE, and they were divided into the following 2 groups: group 1 with ECA (n = 1099) and group 2 without ECA (n = 1247). Patients were evaluated during PSE, at 24 hours, and at 30 days. Statistical significance was defined as p < 0.05. Results Group 1 had fewer minor side effects, such as headache (5/0.5% versus 19/1.5%, p = 0.012) and less reactive hypertension (3/0.3% versus 19/1.5%, p = 0.002); fewer arrhythmias, such as ventricular extrasystoles (180/16.4% versus 247/19.8%, p = 0.032) and paroxysmal supraventricular tachycardia (2/0.2% versus 15/1.2%, p = 0.003); and no adverse events, such as acute myocardial infarction (AMI) or death. In group 2, 1 patient had AMI in < 24 hours (1/01%), and there were 2 deaths in < 30 days (2/0.1%). SonoVue®-related urticaria was seen in 3 (0.3%) patients, without anaphylactic reaction. Conclusion SonoVue® demonstrated safety during PSE. No cases of death, AMI, or anaphylactic reaction were observed. There was a lower incidence of minor side effects and arrhythmias in the group that received ECA, as well as a low incidence of mild allergic reactions.
