NT-proBNP in systemic right ventricles: a new cutoff level for risk stratification?

INTRODUCTION AND OBJECTIVES: The role of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in the risk prediction of patients with systemic right ventricles (sRV) is not well defined. The aim of this study was to analyze the prognostic value of NT-proBNP in patients with an sRV. METHODS: The prognostic value of NT-proBNP was assessed in 98 patients from the SERVE trial. We used an adjusted Cox proportional hazards model, survival analysis, and c-statistics. The composite primary outcome was the occurrence of clinically relevant arrhythmia, heart failure, or death. Correlations between baseline NT-proBNP values and biventricular volumes and function were assessed by adjusted linear regression models. RESULTS: The median age [interquartile range] at baseline was 39 [32-48] years and 32% were women. The median NT-proBNP was 238 [137-429] ng/L. Baseline NT-proBNP concentrations were significantly higher among the 20 (20%) patients developing the combined primary outcome compared with those who did not (816 [194-1094] vs 205 [122-357]; P=.003). In patients with NT-proBNP concentrations> 75th percentile (> 429 ng/L), we found an exponential increase in the sex- and age-adjusted hazard ratio for the primary outcome. The prognostic value of NT-proBNP was comparable to right ventricular ejection fraction and peak oxygen uptake on exercise testing (c-statistic: 0.71, 0.72, and 0.71, respectively). CONCLUSIONS: In patients with sRVs, NT-proBNP concentrations correlate with sRV volumes and function and may serve as a simple tool for predicting adverse outcomes.

2024 SIAC guidelines on cardiorespiratory rehabilitation in pediatric patients with congenital heart disease.

The 2024 Interamerican Society of Cardiology (SIAC) guidelines on cardiorespiratory rehabilitation (CRR) in pediatric patients with congenital heart disease aim to gather and evaluate all relevant evidence available on the topic to unify criteria and promote the implementation of CRR programs in this population in Latin America and other parts of the world. Currently, there is no unified CRR model for the pediatric population. Consequently, our goal was to create these CRR guidelines adapted to the characteristics of congenital heart disease and the physiology of this population, as well as to the realities of Latin America. These guidelines are designed to serve as a support for health care workers involved in the care of this patient group who wish to implement a CRR program in their workplace. The guidelines include an easily reproducible program model that can be implemented in any center. The members of this Task Force were selected by the SIAC on behalf of health care workers dedicated to the care of pediatric patients with congenital heart disease. To draft the document, the selected experts performed a thorough review of the published evidence.

Seguimiento a muy largo plazo tras implante de stent en la coartación de aorta / Very long-term follow-up after aortic stenting for coarctation of the aorta

Introducción y objetivos: El implante de stent es el tratamiento de elección en niños mayores y adultos con coartación aórtica (CoA). El objetivo fue determinar la incidencia de eventos tardíos después del tratamiento con stent. Métodos: Se analizó una cohorte de pacientes con CoA tratados en el centro entre 1993 y 2018 a los que se siguió periódicamente, incluyendo evaluación mediante tomografía computarizada (TC) y fluoroscopia. Resultados: Se incluyó a 167 pacientes con TC y fluoroscopia: 83 (49,7%) ≤ 12 años y 46 (28%) mujeres. El tiempo medio de seguimiento clínico fue de 17±8 años (rango 4-30) y de 11±7 años hasta la TC/fluoroscopia. Se detectó aneurisma en un 13% y se asoció al stent PALMAZ (OR=3,09; IC95%, 1,11-9,49; p=0,036) y a la longitud del stent (OR=0,94; IC95%, 0,89-0,99; p=0,039). La fractura del stent fue frecuente (34%) pero no asociada a la presencia de aneurisma. Se asoció con edad joven (OR=3,57; IC95%, 1,54-8,33; p=0,003), sexo masculino (OR=4,00; IC95%, 1,51-12,50; p=0,008) e inversamente con el stent PALMAZ (OR=0,29; IC95%, 0,12-0,67; p=0,005). La reintervención fue menor en adultos (10%), principalmente por aneurismas. Los pacientes que recibieron tratamiento cuando tenían 12 años o menos presentaron tasas de reintervención más altas (43%) debido al crecimiento somático. Conclusiones: Se observó una incidencia notable de eventos tardíos a largo plazo en pacientes con CoA tratados mediante stent. La reintervención fue más frecuente en pacientes tratados a edades más jóvenes. Parece aconsejable una vigilancia periódica mediante pruebas de imagen. (AU)

Introduction and objectives: Stent implantation is the preferred treatment in older children and adults with aortic coarctation (CoA). We aimed to determine the incidence of very late events after CoA stenting. Methods: We analyzed a cohort of CoA patients who underwent stent implantation at our center between 1993 and 2018. Patients were periodically followed up in outpatient clinics, including computed tomography (CT) and fluoroscopy assessment. Results: A total of 167 patients with CT and fluoroscopy data were included: 83 (49.7%) were aged ≤ 12 years and 46 (28%) were female. The mean clinical follow-up time was 17±8 (range 4-30) years and the mean time to CT/fluoroscopy was 11±7 years. Aortic aneurysm was present in 13% and was associated with the PALMAZ stent (OR, 3.09; 95%CI, 1.11-9.49; P=.036) and the stented length (OR, 0.94; 95%CI, 0.89-0.99; P=.039). Stent fracture was frequent (34%), but was not related to the presence of aneurysm. Stent fracture was associated with young age (OR, 3.57; 95%CI, 1.54-8.33; P=.003), male sex (OR, 4.00; 95%CI, 1.51-12.5, P=.008) and inversely with the PALMAZ stent (OR, 0.29; 95%CI, 0.12-0.67, P=.005). Reintervention was lower in adults (10%), mainly related to aneurysms. Those treated when aged ≤ 12 years had higher reintervention rates (43%) due to recoarctation somatic growth. Conclusions: This long-term follow-up study of CoA patients treated with stenting revealed a significant incidence of late events. Reintervention rates were higher in patients treated at younger ages. Periodic imaging surveillance appears to be advisable. (AU)

Principales características clínicas y epidemiológicas de pacientes con miocardiopatía periparto

Introducción: Las enfermedades cardiovasculares representan una causa importante de morbilidad y mortalidad durante la gestación, entre las que se destaca la miocardiopatía, que cursa como un síndrome de insuficiencia cardíaca. Objetivo: Caracterizar a pacientes con miocardiopatía periparto según variables clínicas y epidemiológicas de interés para la investigación. Métodos: Se realizó un estudio descriptivo y transversal de las 18 pacientes con diagnóstico de miocardiopatía periparto, asistidas en el Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba en el período comprendido desde octubre de 2015 hasta diciembre de 2022. Resultados: En la serie predominaron las pacientes mayores de 35 años de edad (edad promedio de 32,6 años), además de la descendencia africana (50,0 %), la hipertensión arterial crónica (44,4 %) y la multiparidad (8,9 %) como factores de riesgo y la insuficiencia del ventrículo izquierdo como manifestación clínica. La fracción de eyección de dicho ventrículo estuvo regularmente disminuida y la respuesta al tratamiento farmacológico fue satisfactoria en el total de la muestra. Conclusiones: La miocardiopatía en el periparto es de baja incidencia en este centro; sin embargo, por la gravedad que representa, se impone el diagnóstico temprano y la intervención del personal especializado para evitar complicaciones.

Introduction: Cardiovascular diseases represent an important cause of morbidity and mortality during pregnancy, cardiomyopathy is notable as a syndrome of heart failure. Objective: To characterize patients with peripartum cardiomyopathy according to clinical and epidemiological variables of interest for the investigation. Methods: A descriptive and cross-sectional study of 18 patients with diagnosis of peripartum cardiomyopathy was carried out. They were assisted at Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba from October, 2015 to December, 2022. Results: In the series there was a prevalence of patients over 35 years (32.6 average age), besides African descendant (50.0 %), chronic hypertension (44.4 %) and multiparity (8.9 %) as risk factors and the left ventricle failure as clinical manifestation. The ejection fraction of this ventricle was regularly diminished and the pharmacological treatment response was satisfactory in all the sample. Conclusions: Peripartum cardiomyopathy is of low incidence in this center; however, due to its seriousness, the early diagnosis and the specialized staff intervention are necessary to avoid complications.

Epidemiology and outcomes of pediatric cardiac arrest in a cardiovascular unit at a public hospital in Argentina.

BACKGROUND: Children with congenital heart disease present a higher frequency of cardiorespiratory arrest (CRA) than the general pediatric population. The epidemiology of CRA is not exactly known in our setting, nor are the mortality risk or the neurological evolution factors. OBJECTIVE: To describe the epidemiology and outcomes associated with pediatric cardiopulmonary resuscitation in a cardiovascular recovery unit. The primary endpoint was the survival to discharge and the secondary endpoints were the return to spontaneous circulation, the survival at 24 hours and the remote neurological condition. METHODS: Descriptive, prospective, longitudinal cohort study in children under 18 years of age who required cardiopulmonary resuscitation between 2016 and 2019. Demographic variables, characteristics of cardiopulmonary arrest, resuscitation and outcome were analyzed. An uni- and multivariate analysis was performed comparing survivors and deceased. RESULTS: Out of 1,842 hospitalized patients, 4.1% presented CRA. Fifty patients with complete records were analyzed. Seventy-eight percent (39) returned to spontaneous circulation with a high survival rate of 46%. Resuscitation > 6 min and the use of vasoactive drugs were predictors of mortality; 16/23 patients were followed up, 10 of them with normal development for age at 6 months, six had pervasive developmental disorder. CONCLUSIONS: 4.1% of patients presented CRA, with a rate of 3.4 CRA per 1,000 patient-days. Survival at hospital discharge (n = 50) was 46%. Resuscitation > 6 min and the use of vasoactive drugs were independent predictors of mortality. At six months, 63% had normal neurological development for age.

ANTECEDENTES: Los niños con cardiopatías congénitas experimentan paro cardiorrespiratorio (PCR) con mayor frecuencia que la población pediátrica general. Se desconoce la epidemiología exacta del PCR en nuestro medio, al igual que el riesgo de mortalidad y los factores que influyen en la evolución neurológica. OBJETIVO: Describir la epidemiología y los resultados asociados con la reanimación cardiopulmonar pediátrica en una unidad de recuperación cardiovascular. El criterio de valoración primario fue la supervivencia al momento del alta hospitalaria; los secundarios fueron el retorno de la circulación espontánea, la supervivencia a las 24 horas y la condición neurológica en el largo plazo. MÉTODO: Estudio de cohorte longitudinal, descriptivo, prospectivo, en menores de 18 años que requirieron reanimación cardiopulmonar entre 2016 y 2019. Se analizaron las variables demográficas y las características del paro cardiorrespiratorio y de la reanimación, así como su resultado. Se realizaron análisis de una y múltiples variables para comparar a los pacientes sobrevivientes con los fallecidos. RESULTADOS: De los 1,842 pacientes internados, el 4.1% experimentó PCR. Se analizaron 50 pacientes con expedientes completos. Se logró el retorno de la circulación espontánea en el 78% (39), con una supervivencia alta del 46%. La reanimación > 6 min y el uso de fármacos vasoactivos fueron factores predictivos de mortalidad; se realizó el seguimiento de 16/23 pacientes, 10 de ellos con desarrollo normal para la edad luego de seis meses, seis tenían trastorno generalizado del desarrollo. CONCLUSIONES: El 4.1% de los pacientes presentó un PCR, con una tasa de 3.4 PCR por 1,000 días-paciente. La supervivencia al egreso hospitalario (n = 50) fue del 46%. La reanimación > 6 min y la utilización de fármacos vasoactivos fueron factores predictivos independientes de mortalidad. Luego de seis meses, el 63% tenía desarrollo neurológico normal para la edad.

Screening de cardiopatías en niños y adolescentes (Prevencar Program) / Screening for heart disease in kids and adolescents (Prevencar Program)

Objetivo: El objetivo fue desarrollar un cribado de detección de cardiopatías en atención primaria, para identificar alteraciones electrocardiográficas patológicas y cardiopatías subyacentes en adolescentes. Diseño: Durante un año se realizó el estudio mediante muestreo polietápico. Lugar: Se seleccionaron los centros asistenciales de atención primaria en un área de salud, que dispusieran de equipo de electrocardiograma (ECG) digital (12 centros). Participantes: Inicialmente, se reclutó a 718 (16,6%) adolescentes de 14 años y se excluyeron a los que tenían un diagnóstico de cardiopatía previo. Intervención: El cribado consistió en incluir en la revisión obligatoria de los 14 años un cuestionario de salud y un ECG. Principales medidas: Para el cribado se realizó cuestionario, auscultación cardíaca, ECG y ecocardiografía. Se establecieron criterios de anormalidad para remitir a una segunda valoración por un cardiólogo. Resultados: Finalmente la muestra la componen 698 adolescentes, con una edad media de 13,7± 0,5 años, de los cuales 354 (50,7%) fueron chicos. Fueron seleccionados 149 (21,3%) para la segunda revisión por cardiología: 88 (12,6%) por cuestionario positivo, 11 (2,2%) por auscultación cardíaca anormal y 66 (9,5%) por hallazgos en ECG. Los adolescentes con evidencia de cardiopatía fueron 24 (3,4%). De ellos, 14 (2,0%) tuvieron alteraciones sugestivas y se les recomendó seguimiento, 6 (0,9%) tuvieron diagnóstico definitivo de cardiopatía y 4 (0,6%) tenían otros hallazgos patológicos relacionados con el sistema cardiovascular. Conclusiones: El cribado permitió identificar un 1% de adolescentes con cardiopatía y otro 2% permanecerá en seguimiento. El ECG detectó más casos patológicos que el cuestionario.(AU)

Objective: The objective was to develop a screening for heart disease detection in primary care, to identify pathological electrocardiographic changes and underlying heart disease in adolescents. Design: The study was carried out for one year using multistage sampling. Site: Primary care centers in a health area that had digital ECG equipment (12 centers) were selected. Participants: Initially, 718 (16.6%) 14-year-old adolescents were recruited and those with a previous diagnosis of heart disease were excluded. Interventions: Screening consisted of including a health questionnaire in the mandatory 14-year-old check-up. Main measurements: Screening included a questionnaire, cardiac auscultation, ECG and echocardiography. Abnormality criteria were established to refer for a second evaluation by a cardiologist. Results: Finally, the sample was made up of 698 adolescents, with a mean age of 13.7±0.5 years, and 354 (50.7%) were boys. A total of 149 (21.3%) were selected for a second review by cardiology: 88 (12.6%) due to a positive questionnaire, 11 (2.2%) due to abnormal cardiac auscultation, and 66 (9.5%) due to ECG findings. Adolescents with evidence of heart disease were 24 (3.4%). Of these, 14 (2.0%) had suggestive alterations and follow-up was recommended, 6 (0.9%) had a definitive diagnosis of heart disease, and 4 (0.6%) had other pathological findings related to the cardiovascular system. Conclusions: The screening allowed us to identify 1% of adolescents with heart disease and another 2% will remain in follow-up. The ECG detected more pathological cases than the questionnaire.(AU)

Corazón univentricular sin cirugía de Fontan: el tipo de paliación importa / Univentricular hearts not undergoing Fontan: the type of palliation matters

Introducción y objetivos: La información sobre pacientes con fisiología univentricular (FU) y flujo pulmonar restrictivo no sometidos a cirugía de Fontan es escasa. El objetivo de este estudio es comparar la supervivencia y los eventos cardiovasculares en estos pacientes según el tipo de paliación.MétodosLos datos de pacientes con FU se obtuvieron de las bases de datos de 7 centros con unidades de cardiopatías congénitas del adulto. Se excluyó a los pacientes que completaron la circulación de Fontan o desarrollaron un síndrome de Eisenmenger. Se crearon 3 grupos según la fuente de flujo pulmonar: G1, flujo anterógrado pulmonar restrictivo; G2, shunt cavopulmonar, y G3, shunt aortopulmonar±shunt cavopulmonar. El objetivo principal fue la muerte.ResultadosSe identificó a 120 pacientes. La media de edad en la primera visita fue 32,2 años. El seguimiento medio fue de 7,1 años. Se asignó a 55 pacientes (45,8%) al G1, 30 (25%) al G2 y 35 (29,2%) al G3. Los pacientes del G3 tenían peores función renal, clase funcional y fracción de eyección en la primera visita y mostraron una disminución más marcada de la fracción de eyección durante el seguimiento, especialmente en comparación con el G1. Veinticuatro pacientes (20%) fallecieron, 38 (31,7%) ingresaron por insuficiencia cardiaca y 21 (17,5%) presentaron aleteo/fibrilación auricular durante el seguimiento. Estos eventos fueron más frecuentes en el G3 y al compararlos con los del G1 se encontraron diferencias significativas en muerte (HR=2,9; IC95%, 1,14-7,37; p=0,026) y aleteo/fibrilación auricular (HR=2,9; IC95%, 1,11-7,68; p=0,037).ConclusionesEl tipo de paliación de los pacientes con FU y flujo pulmonar restrictivo no sometidos a cirugía de Fontan identifica distintos perfiles. Los pacientes paliados con derivaciones aortopulmonares presentan un peor pronóstico, con más morbilidad y mortalidad. (AU)

Introduction and objectives: There is scarce information on patients with single ventricle physiology (SVP) and restricted pulmonary flow not undergoing Fontan circulation. This study aimed to compare survival and cardiovascular events in these patients according to the type of palliation.MethodsSVP patient data were obtained from the databases of the adult congenital heart disease units of 7 centers. Patients completing Fontan circulation or developing Eisenmenger syndrome were excluded. Three groups were created according to the source of pulmonary flow: G1 (restrictive pulmonary forward flow), G2 (cavopulmonary shunt), and G3 (aortopulmonary shunts±cavopulmonary shunt). The primary endpoint was death.ResultsWe identified 120 patients. Mean age at the first visit was 32.2 years. Mean follow-up was 7.1 years. Fifty-five patients (45.8%) were assigned to G1, 30 (25%) to G2, and 35 (29.2%) to G3. Patients in G3 had worse renal function, functional class, and ejection fraction at the first visit and a more marked ejection fraction decline during follow-up, especially when compared with G1. Twenty-four patients (20%) died, 38 (31.7%) were admitted for heart failure, and 21 (17.5%) had atrial flutter/fibrillation during follow-up. These events were more frequent in G3 and significant differences were found compared with G1 in terms of death (HR, 2.9; 95%CI, 1.14-7.37; P=.026) and atrial flutter/fibrillation (HR, 2.9; 95%CI, 1.11-7.68; P=.037).ConclusionsThe type of palliation in patients with SVP and restricted pulmonary flow not undergoing Fontan palliation identifies distinct profiles. Patients palliated with aortopulmonary shunts have an overall worse prognosis with higher morbidity and mortality. (AU)

Factores pronósticos en el trasplante cardiopulmonar: experiencia a 30 años en un centro de referencia / Prognosis factors in heart–lung transplantation: Thirty years experience in a reference center

Introducción: El trasplante cardiopulmonar (TCP) ha presentado una disminución progresiva en el número de procedimientos. En nuestro país existe poca información al respecto, siendo el objetivo de este estudio analizar la experiencia de un hospital de referencia. Métodos: Estudio observacional unicéntrico de una cohorte histórica en el periodo entre 1990 y 2021. Las asociaciones entre categorías se evaluaron mediante la prueba de X2 o la f de Fisher. La supervivencia se analizó a través del método de Kaplan-Meier. Las diferencias se evaluaron con el estudio de log-rank y el análisis multivariante con el método de Cox. Resultados: Se observó una reducción del número de procedimientos realizados en el último decenio (2000-2009: 19 [44,2%]; 2010-2021: 15 [34,8%]). La mortalidad posoperatoria precoz fue de 23,3%, reduciéndose a 13,3% a partir del 2010. La intrahospitalaria fue de 41%, disminuyendo a 33% en 2010. Los factores asociados a la mortalidad fueron cirugía torácica previa, corticoterapia, circulación extracorpórea (CEC) mayor a 200 min, tiempo de isquemia mayor a 300 min y dehiscencia traqueal (p < 0,005). La supervivencia global a uno, cinco y 10 años fue de 58, 44,7 y 36,1%, respectivamente. Los factores asociados a menores tasas de supervivencia fueron cirugía torácica previa, donante masculino, CEC mayor 200 min, tiempo de isquemia mayor a 300 min, dehiscencia traqueal y diferencia de pesos (p < 0,005). Conclusiones: Existe una disminución en el número de procedimientos, siendo más evidente en la última década, pero evidenciando una mejora tanto de la mortalidad posoperatoria y supervivencia.(AU)

Introduction: Heart–lung transplantation has shown a progressive decrease in the number of procedures. There is a lack of information about this field in Spain. The main goal of this study is to analyze the experience of a national reference hospital. Methods: We performed a retrospective study of a historical cohort of heart–lung transplanted patients in a single center, during a 30 years period (from 1990 to 2021). The associations between variables were evaluated using the χ2 test or Fisher's exact test. Survival was analyzed using the Kaplan–Meier method. Differences were evaluated using the log-rank test and multivariate analysis with the Cox method. Results: A decrease in the number of procedures performed in the last decade was observed [2000–2009: 19 procedures (44.2%); 2010–2021: 15 procedures (34.8%)]. Early postoperative mortality was 23.3%, falling to 13.3% from 2010. In-hospital mortality was 41%, falling to 33% from 2010. Main factors related to higher mortality: previous thoracic surgery, corticosteroid therapy, extracorporeal circulation (ECLS) greater than 200 min, ischemia time greater than 300 min, and tracheal dehiscence (p < 0.005). Overall survival at one, five, and ten years was 58%, 44.7%, and 36.1%, respectively. Factors associated with lower survival rates: previous thoracic surgery, male donor, extracorporeal circulation greater than 200 min, ischemia time greater than 300 min, tracheal dehiscence and weight difference (p < 0.005). Conclusions: There has been a progressive decrease in the number of heart–lung transplantations, being more evident in the last decade, but showing an improvement in both mortality and survival.(AU)

Adolescents with evidence of heart disease were 24 (3.4%). Of these, 14 (2.0%) had suggestive alterations and follow-up was recommended, 6 (0.9%) had a definitive diagnosis of heart disease, and 4 (0.6%) had other pathological findings related to the cardiovascular system. CONCLUSIONS: The screening allowed us to identify 1% of adolescents with heart disease and another 2% will remain in follow-up. The ECG detected more pathological cases than the questionnaire.

Prognosis factors in heart-lung transplantation: 30 years experience in a reference center.

INTRODUCTION: Heart-lung transplantation has shown a progressive decrease in the number of procedures. There is a lack of information about this field in Spain. The main goal of this study is to analyze the experience of a national reference hospital. METHODS: We performed a retrospective study of a historical cohort of heart-lung transplanted patients in a single center, during a 30 years period (from 1990 to 2021). The associations between variables were evaluated using the χ2 test or Fisher's exact test. Survival was analyzed using the Kaplan-Meier method. Differences were evaluated using the log-rank test and multivariate analysis with the Cox method. RESULTS: A decrease in the number of procedures performed in the last decade was observed [2000-2009: 19 procedures (44.2%); 2010-2021: 15 procedures (34.8%)]. Early postoperative mortality was 23.3%, falling to 13.3% from 2010. In-hospital mortality was 41%, falling to 33% from 2010. Main factors related to higher mortality: previous thoracic surgery, corticosteroid therapy, extracorporeal circulation (ECLS) greater than 200 min, ischemia time greater than 300 min, and tracheal dehiscence (p < 0.005). Overall survival at one, five, and ten years was 58%, 44.7%, and 36.1%, respectively. Factors associated with lower survival rates: previous thoracic surgery, male donor, extracorporeal circulation greater than 200 min, ischemia time greater than 300 min, tracheal dehiscence and weight difference (p < 0.005). CONCLUSIONS: There has been a progressive decrease in the number of heart-lung transplantations, being more evident in the last decade, but showing an improvement in both mortality and survival.

Very long-term follow-up after aortic stenting for coarctation of the aorta.

INTRODUCTION AND OBJECTIVES: Stent implantation is the preferred treatment in older children and adults with aortic coarctation (CoA). We aimed to determine the incidence of very late events after CoA stenting. METHODS: We analyzed a cohort of CoA patients who underwent stent implantation at our center between 1993 and 2018. Patients were periodically followed up in outpatient clinics, including computed tomography (CT) and fluoroscopy assessment. RESULTS: A total of 167 patients with CT and fluoroscopy data were included: 83 (49.7%) were aged ≤ 12 years and 46 (28%) were female. The mean clinical follow-up time was 17±8 (range 4-30) years and the mean time to CT/fluoroscopy was 11±7 years. Aortic aneurysm was present in 13% and was associated with the PALMAZ stent (OR, 3.09; 95%CI, 1.11-9.49; P=.036) and the stented length (OR, 0.94; 95%CI, 0.89-0.99; P=.039). Stent fracture was frequent (34%), but was not related to the presence of aneurysm. Stent fracture was associated with young age (OR, 3.57; 95%CI, 1.54-8.33; P=.003), male sex (OR, 4.00; 95%CI, 1.51-12.5, P=.008) and inversely with the PALMAZ stent (OR, 0.29; 95%CI, 0.12-0.67, P=.005). Reintervention was lower in adults (10%), mainly related to aneurysms. Those treated when aged ≤ 12 years had higher reintervention rates (43%) due to recoarctation somatic growth. CONCLUSIONS: This long-term follow-up study of CoA patients treated with stenting revealed a significant incidence of late events. Reintervention rates were higher in patients treated at younger ages. Periodic imaging surveillance appears to be advisable.

Profile of cardiovascular diseases and physiotherapeutic intervention in a hospital emergency service / Perfil das doenças cardiovasculares e atuação fisioterapeutica em um serviço de emergência hospitalar

Abstract Introduction Cardiovascular disease (CVD) is the lead-ing cause of death globally, with a high proportion of hospitalizations and costs. In view of this, it is essential to understand the main CVDs in patients admitted to hospital emergency services and the role of physiotherapists, in order to plan and direct health services, and to denote participation and encourage specific physiotherapy training in the context of tertiary care. Objective To outline the profile of cardiovascular emergencies and to evaluate physiotherapy in adult patients in the emergency department of a hospital in the interior of the state of São Paulo. Methods This was an observational study which analyzed 1,256 on-call records over a period of eight months. The data collected included age, gender, cardiovascular diagnostic hypothesis and physiotherapy treatment carried out. Results A total of 75 patients with cardiovascular emergencies were included, the most prevalent of which were: heart failure (n = 21), acute coronary syndrome (n = 14), acute myocardial infarction (n = 13), bradyarrhythmia (n = 6) and hypertensive crisis (n = 5). Regarding physiotherapeutic actions and their applications, the most frequent were invasive mechanical ventilation management (n = 34), lung re-expansion maneuvers (n = 17), orotracheal intubation assistance (n = 17), non-invasive mechanical ventilation (n = 14), bronchial hygiene maneuvers (n = 12), kinesiotherapy (n = 10) and sedation (n = 10). Conclusion Heart failure and acute coronary syndrome were the cardiovascular diseases that caused the most admissions to the hospital emergency department and that the procedures with an emphasis on the respiratory system were the most applied.

Resumo Introdução As doenças cardiovasculares (DCV) repre-sentam a principal causa de morte global, destacando-se em internações e gastos. Diante disso, é essencial compreender as principais DCV em pacientes admitidos em serviços de emergência hospitalar e a atuação do fisioterapeuta para planejamento e direcionamento dos serviços de saúde e para denotar a participação e incentivar formações fisioterapêuticas específicas no contexto da atenção terciária. Objetivo Traçar o perfil de emergências cardiovasculares e avaliar a atuação fisioterapêutica em pacientes adultos de serviço de emergência de um hospital no interior do estado de São Paulo. Métodos Trata-se de um estudo observacional, em que foram analisadas 1.256 fichas de passagem de plantão, no período de oito meses. Os dados coletados foram idade, sexo, hipótese diagnóstica cardiovascular e tratamento fisioterapêutico realizado. Resultados Foram incluídos 75 pacientes que apresentavam o perfil de emergências cardiovasculares, sendo as mais prevalentes: insuficiência cardíaca (n = 21), síndrome corona-riana aguda (n = 14), infarto agudo do miocárdio (n = 13), bradarritmia (n = 6) e crise hipertensiva (n = 5). Em relação à atuação fisioterapêutica e suas aplicações, as mais frequentes foram manejo da ventilação mecânica invasiva (n = 34), manobras de reexpansão pulmonar (n = 17), auxílio a intubação orotraqueal (n = 17), ventila-ção mecânica não invasiva (n = 14), manobras de higiene brônquica (n = 12), cinesioterapia (n = 10) e sedestação (n = 10). Conclusão A insuficiência cardíaca e a síndrome coronária aguda foram as doenças cardiovasculares que mais ocasionaram internação no serviço de emergência hospitalar e as condutas com ênfase no aparelho respiratório foram as mais aplicadas.

Patients' prognosis with congenital heart disease followed by ten years: survival and associated factors / Prognóstico de pacientes com cardiopatia congênita seguidos por dez anos: sobrevida e fatores associados

ABSTRACT Objective: To evaluate the prognosis and influence of associated factors in patients with congenital heart disease admitted for the first time to the Intensive Care Unit of the Hospital da Criança Santo Antônio/Irmandade da Santa Casa de Misericórdia de Porto Alegre, especially those factors associated with death. Methods: Patients were prospectively and consecutively allocated over a period of one year (August 2005 to July 2006). Now, 15 years after the initial selection, we collected data from these patients in the database of the Cytogenetics Laboratory of the Universidade Federal de Ciências da Saúde de Porto Alegre and in the medical records of the hospital. Results: Of the 96 patients, 11 died and 85 were alive until 20 years old. Four patients died in the Intensive Care Unit. The survival probability up to 365 days of life was 95.8%. The survival assessment identified that the deaths occurred mainly before the patients completed one thousand days of life. We found that complex heart disease was independently associated with an odds ratio of 5.19 (95% confidence interval — CI:1.09-24.71; p=0.038) for death. Conclusions: Knowledge about the factors that interfere with the prognosis can be crucial in care practice planning, especially considering that congenital heart disease is an important cause of mortality in the first year of life.

RESUMO Objetivo: Avaliar o prognóstico e a influência de fatores associados em pacientes com cardiopatia congênita internados pela primeira vez na Unidade de Terapia Intensiva do Hospital da Criança Santo Antônio/Irmandade da Santa Casa de Misericórdia de Porto Alegre, principalmente aqueles fatores associados ao óbito. Métodos: Os pacientes foram alocados prospectiva e consecutivamente por um período de um ano (agosto de 2005 a julho de 2006). Agora, 15 anos após a seleção inicial, coletamos dados desses pacientes no banco de dados do Laboratório de Citogenética da Universidade Federal de Ciências da Saúde de Porto Alegre e nos prontuários do hospital. Resultados: Dos 96 pacientes, 11 faleceram e 85 permaneceram vivos até completar 20 anos. Quatro pacientes morreram na Unidade de Terapia Intensiva. A probabilidade de sobrevida até 365 dias de vida foi de 95,8%. A avaliação da sobrevida identificou que os óbitos ocorreram principalmente antes de os pacientes completarem mil dias de vida. Verificamos que a doença cardíaca complexa foi independentemente associada a um odds ratio de 5,19 (intervalo de confiança — IC95% 1,09-24,71; p=0,038) para morte. Conclusões: O conhecimento dos fatores que interferem no prognóstico pode ser fundamental no planejamento da prática assistencial, principalmente considerando-se que as cardiopatias congênitas são importante causa de mortalidade no primeiro ano de vida.

Patau and Edwards Syndromes in a University Hospital: beyond palliative care / Síndrome de Edwards e Patau em um hospital universitário: além do paliativo

ABSTRACT Objective: To describe the newborn population with Patau (T13) and Edwards Syndrome (T18) with congenital heart diseases that stayed in the Intensive Care Unit (ICU) of a quaternary care hospital complex, regarding surgical and non-surgical medical procedures, palliative care, and outcomes. Methods: Descriptive case series conducted from January/2014 to December/2018 through analysis of records of patients with positive karyotype for T13 or T18 who stayed in the ICU of a quaternary hospital. Descriptive statistics analysis was applied. Results: 33 records of eligible patients were identified: 27 with T18 (82%), and 6 T13 (18%); 64% female and 36% male. Eight were preterm infants with gestational age between 30-36 weeks (24%), and only 4 among the 33 infants had a birth weight >2500 g (12%). Four patients underwent heart surgery and one of them died. Intrahospital mortality was 83% for T13, and 59% for T18. The majority had other malformations and underwent other surgical procedures. Palliative care was offered to 54% of the patients. The median hospitalization time for T18 and T13 was 29 days (range: 2-304) and 25 days (13-58), respectively. Conclusions: Patients with T13 and T18 have high morbidity and mortality, and long hospital and ICU stays. Multicentric studies are needed to allow the analysis of important aspects for creating protocols that, seeking therapeutic proportionality, may bring better quality of life for patients and their families.

RESUMO Objetivo: Descrever a população de recém-nascidos com síndrome de Patau (T13) e Edwards (T18) portadores de cardiopatias congênitas, que permaneceram em Unidades de Terapia Intensiva (UTI) de um complexo hospitalar quaternário, com relação a conduta cirúrgica ou não, cuidados paliativos e seus desfechos. Métodos: Série de casos de pacientes internados entre janeiro de 2014 a dezembro de 2018, com análise dos prontuários de portadores de T13 ou T18 que permaneceram internados em UTI que recebem neonatos nesse hospital quaternário. Utilizou-se análise estatística descritiva. Resultados: Foram identificados 33 prontuários para análise — 27 T18 (81,8%) e seis T13 (18,2%); 64% do sexo feminino e 36% do sexo masculino. Oito foram prematuros, nascidos com 30 a 36 semanas (24,2%), e apenas quatro nasceram com mais de 2500 g (12,1%). Quatro pacientes foram submetidos a cirurgia cardíaca e um deles foi a óbito. A mortalidade intra-hospitalar foi de 83% para T13 e 59% para T18. A maioria apresentava outras malformações e foi submetida a outras cirurgias. Cuidados paliativos foram oferecidos a 54% dos pacientes. A mediana do tempo de hospitalização para T18 e T13 foi respectivamente de 29 dias (variação: 2-304) e 25 dias (13-58). Conclusões: Pacientes com T13 e T18 cursam com alta morbimortalidade e longa permanência hospitalar em UTI. São necessários estudos multicêntricos para melhor análise de aspectos importantes para a criação de protocolos que, buscando proporcionalidade terapêutica, tragam melhor qualidade de vida para os pacientes e suas famílias.
