ABSTRACT

O infarto agudo do miocárdio no período gravídico-puerperal é uma condição rara em que a principal causa é a dissecção espontânea da artéria coronária. É um evento comumente subdiagnosticado, com pouca literatura disponível e elevado índice de morbimortalidade. Esse relato descreve o caso de uma gestante de 36 semanas de gravidez gemelar, monocoriônica-diamniótica, com infarto agudo do miocárdio secundário à dissecção espontânea da artéria coronária. As equipes de cirurgia cardíaca e obstetrícia optaram pela realização de parto cesariano e histerectomia subtotal, seguido da revascularização da artéria mamária descendente anterior. Discutem-se as orientações adotadas na dissecção espontânea da artéria coronária, bem como a abordagem terapêutica e a conduta obstétrica, quando essa condição ocorre durante a gravidez.(AU)


Acute myocardial infarction in the pregnancy-puerperal period is a rare condition the main cause of which is the spontaneous coronary artery dissection. A commonly underdiagnosed event with little available literature and a high rate of morbidity and mortality. This case reports a 36-week pregnant woman of mono-chorionic-diamniotic pregnancy who had a myocardial infarction secondary to a spontaneous coronary artery dissection. In a joint discussion between the team of cardiac surgery and obstetrics, it was decided to perform a cesarean delivery and subtotal hysterectomy followed by revascularization of the mammary anterior descendant. It discusses the conducts to be adopted in a case of spontaneous coronary artery dissection as well as therapeutic approaches and obstetric conducts to be taken in a case of dissection during pregnancy.(AU)

ABSTRACT

A case of probable coronary arteritis in a young girl who died suddenly and unexpectedly is presented. The histologic presentation of the disorder is discussed, especially the differential diagnosis of arteritis of the coronary arteries with an emphasis on tuberculosis (TB). TB myocarditis with or without concomitant lung involvement is rare, and tubercular coronary arteritis without underlying pulmonary Koch's disease is all the rarer. We herein describe a case where the cause of death was ascertained on post-mortem examination.

ABSTRACT

Fístulas de artérias coronárias têm incidência baixa, sendo diagnosticadas mais frequentemente pelo ecocardiograma ou angiotomografia coronariana, embora a cineangiocoronariografia seja o método padrão-ouro. Têm origem mais comumente na artéria coronária direita, sendo a drenagem para câmaras de baixa pressão o mais habitual. O tratamento pode ser expectante, cirúrgico ou percutâneo. Este relato descreve o caso de uma rara apresentação de insuficiência cardíaca, dada por fístula da coronária circunflexa com drenagem para o átrio esquerdo. (AU)


Coronary artery fistulas have a low incidence and are often diagnosed by echocardiography or coronary computed tomography angiography, although coronary angiography is the gold standard. They commonly originate in the right coronary artery, with drainage to low-pressure chambers being the most frequent finding. Treatment can be expectant, surgical, or percutaneous. This report describes a case of a rare presentation of heart failure due to a fistula of the circumflex coronary artery with drainage into the left atrium. (AU)

ABSTRACT

OBJECTIVE@#To study the clinical features of children with recurrent Kawasaki disease (KD).@*METHODS@#PubMed, Web of Science, Embase, CNKI, Wanfang Med Online, and Weipu Data were searched for case-control studies on the clinical features of initial and recurrent KD. The articles were screened according to the inclusion and exclusion criteria. RevMan 5.3 software was used to perform the Meta analysis. Effect models were selected based on the results of heterogeneity test, and then pooled @*RESULTS@#A total of 9 case-control studies were included, with 12 059 children with KD in total, among whom 206 children had recurrent KD (127 boys/61.7%; 79 girls/38.3%). The results of the Meta analysis showed that compared with the initial KD onset, the children with recurrent KD had a shorter duration of fever (@*CONCLUSIONS@#Current evidence shows that children with recurrent KD tend to have a shorter duration of fever and a lower incidence of swelling of the hands and feet. KD recurrence is more common in boys. Current evidence does not show an increased risk of developing coronary artery lesions in children with recurrent KD.

ABSTRACT

El origen anómalo de la arteria coronaria derecha de la arteria pulmonar es una entidad rara con una incidencia del 0,002 % y potencialmente grave, que puede causar muerte súbita. El diagnóstico frecuentemente es incidental, secundario a evaluaciones por soplos cardíacos a diferencia del origen anómalo de la arteria coronaria izquierda de la arteria pulmonar, reconocido por presentar isquemia miocárdica e insuficiencia cardíaca. Se reporta el caso de una niña de 6 meses evaluada por un soplo y derivada por sospecha de fístula coronaria. La evaluación mediante ecocardiograma doppler color, cateterismo cardíaco y angiotomografía mostró la presencia de una comunicación interauricular ostium secundum pequeña y origen anómalo de la arteria coronaria derecha de la arteria pulmonar. A los 11 meses, se realizó una cirugía de reimplante de la arteria coronaria derecha en la arteria aorta y el cierre de la comunicación interauricular.


The anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare entity that has an incidence of 0.002 % and can potentially cause sudden death. Unlike to the anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), usually presented with myocardial ischemia and heart failure; the diagnosis of ARCAPA is often incidental during evaluation of a heart murmur. We report a case of a 6 months old female patient referred to us with a cardiac murmur and a suspicion of coronary fistula. For a proper diagnostic assessment an echocardiogram, a computed tomography angiography and a cardiac catheterization were requested. A small ostium secundum-type atrial septal defect (ASD) and an ARCAPA were revealed. At 11 months old, the patient was scheduled for corrective cardiovascular surgery. The aim of this report is to describe a low incidence and potentially fatal disease.

ABSTRACT

Fundamento: As doenças cardiovasculares são a principal causa de morte no Brasil. Marcadores bioquímicos possuem importância diagnóstica e prognóstica nas síndromes coronarianas agudas (SCAs), sendo a troponina o biomarcador preferido. Estudos já demonstram relação positiva entre elevação da troponina ultrassensível (TnUs) e prognóstico. Entretanto, poucos relacionam seus níveis com a complexidade das lesões coronárias. Objetivos: Comparar níveis de TnUs com a complexidade das lesões coronarianas pelo escore SYNTAX e relacionar os escores TIMI e GRACE com os níveis desse biomarcador em pacientes com SCA. Métodos: Estudo retrospectivo, transversal com 174 indivíduos com SCA. A correlação entre as variáveis foi avaliada pelo teste de correlação linear não paramétrico de Spearman e a análise estatística realizada pelo programa SPSS, com nível de significância de 5%. Resultados: A média de idade foi 63 anos, predominando o sexo feminino (52,9%). A maioria dos pacientes era hipertensa, não diabética e não tabagista. Dos pacientes avaliados, 19,0% apresentaram IAM com SST, 43,1% IAM sem SST e 36,8% angina instável. A maioria encontrava-se em Killip 1 (82,8%). A mediana de TnUs foi de 67pg/ml. As medianas dos escores de risco foram de 3, 121 e 3 pontos nas escalas TIMI, GRACE e SYNTAX, respectivamente. Houve correlação da taxa de TnUs com os escores SYNTAX (p < 0,001, r = 0,440), TIMI (p < 0,001, r = 0,267) e GRACE (p = 0,001, r = 0,261). Conclusão: Encontrada correlação linear positiva entre os níveis de TnUs e complexidade das lesões coronarianas, assim como entre esse biomarcador e os escores clínicos TIMI e GRACE


Background: Cardiovascular diseases are the leading cause of death in Brazil. Biochemical markers have diagnostic and prognostic importance in acute coronary syndromes (ACSs), with troponin as the preferred biomarker. Studies have already demonstrated a positive relationship between increased levels of high-sensitivity troponin (hsTn) and prognosis. However, few studies have correlated hsTn levels with the complexity of coronary lesions. Objectives: To compare hsTn levels with the complexity of coronary lesions according to the SYNTAX score, and to correlate the levels of this biomarker with the TIMI and GRACE scores in patients with ACS. Methods: Retrospective, cross-sectional study with 174 patients with ACS. The correlation between variables was assessed by the nonparametric Spearman's rank correlation, and statistical analysis was performed by the SPSS program, with a significance level of 5%. Results: Mean age was 63 years, and most patients were women (52.9%), hypertensive, non-diabetic and non-smokers. Nineteen percent of the patients had STEMI, 43.1% NSTEMI, and 36.8% unstable angina. Most were in Killip 1 (82.8%). Median hsTn was 67 pg/mL. Median risk scores were 3, 121 and 3 in the TIMI, GRACE and SYNTAX scores, respectively. There was a correlation of hsTn with SYNTAX (p <0.001, r = 0.440), TIMI (p < 0.001, r = 0.267) and GRACE (p = 0.001, r = 0.261) scores. Conclusion: A positive linear correlation was found of hsTn levels with the complexity of coronary lesions, and with the TIMI and GRACE

ABSTRACT

PURPOSE: Intravenous immunoglobulin (IVIG) is the standard treatment for Kawasaki disease (KD). However, there is still no standard treatment for IVIG-resistant KD. This study aimed to evaluate the efficacy of low-dose methotrexate (MTX) as a treatment for IVIG-resistant KD. MATERIALS AND METHODS: We retrospectively analyzed 10-year data for patients with IVIG-resistant KD who were administered MTX at Severance Children's Hospital. RESULTS: The subjects included 75 patients with KD aged 5 months to 9.2 years who had been administered MTX. Their maximum body temperatures decreased significantly within 24 h of therapy. The patients' C-reactive protein levels were significantly lower 1 week after administering the first dose of MTX than those before treatment. No adverse effect for MTX was observed. CONCLUSION: MTX treatment of IVIG-resistant KD resulted in rapid defervescence, improvement of clinical symptoms, and normalization of acute-phase reactants in all patients. Thus, MTX could be a candidate treatment for IVIG-resistant KD.

ABSTRACT

Los puentes intramiocárdicos son una anomalía de la circulación coronaria. Estos suelen presentarse en el trayecto de la arteria descendente anterior y se clasifican en superficiales o profundos. Reportamos el hallazgo de un puente intramiocárdico en el trayecto de la arteria coronaria derecha, incluida su rama sinoauricular y descendente posterior durante la disección de rutina de un cadáver. El paciente al parecer no presentó signos relativos a insuficiencia coronaria y falleció debido a una insuficiencia respiratoria aguda causada por neumonía aspirativa. Debido a la presencia limitada de casos sobre puente intramiocárdico de la arteria coronaria derecha, realizamos una revisión de la literatura al respecto y planteamos algunas conclusiones.


Intramyocardial bridges are a coronary circulation anomaly. They usually occur on the path of the anterior descending artery and are classified as superficial or deep. During a routine autopsy, we found­and report­an intramyocardial bridge in large part of the right coronary artery pathway, including the sinoatrial and posterior descending branch. The patient did not show signs of coronary insufficiency, and died from an acute respiratory failure caused by aspiration pneumonia. Due to the infrequency of cases of intramyocardial bridges of the right coronary artery without concomitant clinical symptoms or signs, we conducted a literature review in this regard.

ABSTRACT

Dialysis-related amyloidosis predominantly occurs in osteo-articular structures and dialysis-related amyloid (DRA) substances also deposit in extra-articular tissues. Clinical manifestations of DRA include odynophagia, gastrointestinal hemorrhage, intestinal obstruction, kidney stones, myocardial dysfunction, and subcutaneous tumors. The pathological characteristics of DRA in the heart of hemodialysis patients have rarely been reported. We report the case of a 73-year-old female with a history of cerebral palsy and end-stage renal disease status post two failed renal transplants who had been on hemodialysis for 30 years. The patient was admitted with the working diagnosis of pneumonia. An echocardiography showed markedly reduced biventricular function manifested by low blood pressure with systolic in the 70s and elevated pulmonary artery pressure of 45 mmHg, which did not respond to therapy. Following her demise, the autopsy revealed bilateral pulmonary edema and pleural effusions. There was cardiac amyloid deposition exclusively in the coronary arteries but not in the perimyocytic interstitium. Amyloids were also found in pulmonary and intrarenal arteries and the colon wall. Previous case reports showed that beta 2-microglobulin amyloid deposits in various visceral organs but less frequently in the atrial and/or the ventricular myocardium. In the present case, amyloids in the heart were present in the intramural coronary arteries causing myocardial ischemia and infarction, which was the immediate cause of death.

ABSTRACT

Introducción: La enfermedad de Kawasaki es una vasculitis sistémica con riesgo de afectación coronaria. Nuestro objetivo es identificar los factores de riesgo asociados a la afectación coronaria en pacientes con enfermedad de Kawasaki completa e incompleta. Material y métodos: Estudio descriptivo retrospectivo de los pacientes diagnosticados con enfermedad de Kawasaki en un hospital terciario entre 2008 y 2014. Se utilizaron los criterios diagnósticos de la Asociación Americana de Cardiología para definir la enfermedad de Kawasaki en su forma completa e incompleta. Resultados: Treinta y un niños fueron diagnosticados con enfermedad de Kawasaki; 24 cumplían criterios para la forma completa y 7, para la incompleta. Cinco presentaron afectación coronaria. Uno de ellos presentaba enfermedad de Kawasaki incompleta (1/7= 14,3%), y los 4 restantes, enfermedad de Kawasaki completa (4/24= 16,7%). No se encontraron diferencias significativas en el riesgo de afectación coronaria entre ambos grupos (p= 1,0). Los pacientes con afectación coronaria tenían una proteína C reactiva mayor (mediana: 16,2 mg/dl vs. 8,4 mg/dl; p= 0,047) y una menor albuminemia (mediana: 3,2 mg/dl vs. 3,99 mg/dl; p= 0,002). Conclusiones: El riesgo de afectación coronaria de la enfermedad de Kawasaki incompleta es similar al de la enfermedad de Kawasaki completa, por lo que, en pacientes con la forma incompleta de la enfermedad, no se debería demorar el tratamiento con inmunoglobulina. En nuestra población, los valores de proteína C reactiva y de albúmina se relacionan con un mayor riesgo de afectación coronaria.


Introduction: Kawasaki disease refers to systemic vasculitis with risk of coronary artery disease. Our objective is to identify risk factors associated with coronary artery disease in patients with complete and incomplete Kawasaki disease. Material and methods: Descriptive, retrospective study conducted in patients diagnosed with Kawasaki disease in a tertiary-care hospital between 2008 and 2014. The American Heart Association diagnostic criteria were used to define complete and incomplete Kawasaki disease. Results: Thirty-one children were diagnosed with Kawasaki disease; 24 met the criteria for the complete form, and 7, for the incomplete form of this condition. Five had coronary artery disease. One of them had incomplete Kawasaki disease (1/7= 14.3%), and the remaining four had the complete form (4/24= 16.7%). No significant differences were found between both groups (p= 1.0). Patients with coronary artery involvement had a higher C-reactive protein level (median: 16.2 mg/dL versus 8.4 mg/dL, p= 0.047) and lower albuminemia (median: 3.2 mg/dL versus 3.99 mg/dL, p= 0.002). Conclusions: The risk of coronary artery involvement in incomplete Kawasaki disease is similar to that in complete Kawasaki disease; therefore, in patients with the incomplete form, immunoglobulin therapy should not be delayed. In our population, C-reactive protein and albumin levels were related to a higher risk of coronary artery involvement.

ABSTRACT

PURPOSE: This study compared the angiographic outcomes of paclitaxel-coated balloon (PCB) versus plain old balloon angioplasty (POBA) treatment for de novo coronary artery lesions. At present, there is no available data comparing the efficacy of PCB versus POBA for the treatment of de novo coronary lesions. MATERIALS AND METHODS: This multicenter retrospective observational study enrolled patients with de novo coronary lesions with a reference vessel diameter between 2.5 mm and 3.0 mm and lesion length or =50%) in POBA, compared to PCB (30.4%, n=7 vs. 4.1%, n=2, p<0.001). Target vessel revascularization was higher in the POBA group (13.0%, n=3 vs. 0%, p=0.033). CONCLUSION: PCB treatment of de novo coronary lesions showed better 9-month angiographic outcomes than POBA treatment alone.

ABSTRACT

PURPOSE: The effects on the side-branch (SB) ostium, following paclitaxel-coated balloon (PCB) treatment of de novo coronary lesions of main vessels have not been previously investigated. This study was aimed at evaluating the serial morphological changes of the SB ostium after PCB treatment of de novo coronary lesions of main vessels using optical coherence tomography (OCT). MATERIALS AND METHODS: This prospective, single-center observational study enrolled patients with de novo lesions, which were traversed by at least one SB (≥1.5 mm) and were treated with PCB. The SB ostium was evaluated with serial angiographic and OCT assessments pre- and post-procedure, and at 9-months follow-up. RESULTS: Sixteen main vessel lesions were successfully treated with PCB, and 26 SBs were included for analysis. Mean SB ostial lumen area increased at 9-months follow-up (0.92±0.68 mm2 pre-procedure, 1.03±0.77 mm2 post-procedure and 1.42±1.18 mm2 at 9-months). The SB ostial lumen area gain was 0.02±0.24 mm2 between pre- and post-procedure, 0.37±0.64 mm2 between post-procedure and 9-months, and 0.60±0.93 mm2 between pre-procedure and 9-months. The ostial lumen area increased by 3.9% [interquartile range (IQR) of -33.3 to 10.4%] between pre- and post-procedure, 52.1% (IQR of -0.7 to 77.3%) between post-procedure and 9-months and 76.1% (IQR of 18.2 to 86.6%) between pre-procedure and 9-months. CONCLUSION: PCB treatment of de novo coronary lesions of main vessels resulted in an increase in the SB ostial lumen area at 9-months.

ABSTRACT

PURPOSE: When performing coronary angiography (CAG), diagnostic catheter intubation to the ostium can cause damping of the pressure tracing. The aim of this study was to determine the predictors of atherosclerotic ostial stenosis in patients showing pressure damping during CAG. MATERIALS AND METHODS: In total, 2926 patients who underwent diagnostic CAG were screened in this study. Pressure damping was defined as an abrupt decline of the coronary blood pressure with a blunted pulse pressure after engagement of the diagnostic catheter. According to CAG and intravascular ultrasound (IVUS), we divided damped ostia into two groups: atherosclerotic ostial lesion group (true lesion group) and non-atherosclerotic ostium group (false lesion group). Clinical and angiographic characteristics were compared between the two groups. RESULTS: The overall incidence of pressure damping was 2.3% (68 patients and 76 ostia). Among the pressure damped ostia, 40.8% (31 of 76 ostia) were true atherosclerotic ostial lesions (true lesion group). The true lesion group had more frequent left main ostial damping and more percutaneous coronary interventions (PCIs) performed on non-ostial lesions, compared to the false lesion group. On multivariate logistic regression analysis, left main ostial damping [hazard ratio (HR) 4.11, 95% confidence interval (CI) 1.24-13.67, p=0.021] and PCI on non-ostial lesion (HR 5.34, 95% CI 1.34-21.27, p=0.018) emerged as independent predictors for true atherosclerotic ostial lesions in patients with pressure damping. CONCLUSION: Left main ostial damping and the presence of a non-ostial atherosclerotic lesion may suggest a significant true atherosclerotic lesion in the coronary ostium.
