Epicardial Ablation for Ventricular Tachycardia in Chronic Chagas Heart Disease
O envolvimento cardíaco é a manifestação mais frequente e grave da doença de Chagas. Após a infecção, a maioria dos indivíduos permanece sem manifestação da doença ao longo da vida, mas pelo menos 30% desenvolvem múltiplos distúrbios do ritmo cardíaco, sintomas graves de insuficiência cardíaca e fenômenos tromboembólicos, em geral, após 10 a 30 anos da infecção inicial. A miocardite crônica pre...
متن کاملThe apical ventricular lesion in Chagas' heart disease.
Apical lesions of the left ventricle, ranging from endocardial thickening to aneurysms, are commonly found in Chagas' heart disease. These abnormalities can be identified by ventriculography, two-dimensional echocardiography and radioisotopic studies. Generally, clinical manifestations are limited to arrhythmias and thromboembolic. The lesions are usually small and apparently do not play a role...
متن کاملIs autonomic function associated with left ventricular systolic function in Chagas heart disease patients undergoing treatment for heart failure?
INTRODUCTION The association between cardiac autonomic and left ventricular (LV) dysfunction in Chagas disease (ChD) is controversial. METHODS A standardized protocol that includes the Valsalva maneuver, a respiratory sinus arrhythmia (RSA) test, and an echocardiographic examination was used. Spearman correlation coefficients (rho) were used to investigate associations. RESULTS The study po...
متن کاملFunctional capacity and right ventricular function in patients with Chagas heart disease.
AIMS Right ventricular (RV) dysfunction is an important factor on effort tolerance in cardiopulmonary diseases. Nevertheless, the role of RV function in predicting exercise capacity in patients with Chagas disease has not been reported. This study aims to evaluate whether RV function assessed by tissue Doppler can predict functional capacity in patients with Chagas heart disease. METHODS AND ...
متن کاملVentricular arrhythmias in Chagas disease.
Sudden death is one of the most characteristic phenomena of Chagas disease, and approximately one-third of infected patients develop life-threatening heart disease, including malignant ventricular arrhythmias. Fibrotic lesions secondary to chronic cardiomyopathy produce arrhythmogenic substrates that lead to the appearance and maintenance of ventricular arrhythmias. The objective of this study ...
