PURPOSE: To evaluate some features of ventricular arrhythmias in patients with mitral valve prolapse. METHODS: We studied 25 patients (female: 19; mean age: 37 +/- 13 years) with ventricular arrhythmias, mitral valve prolapse and normal ventricular function. All patients underwent a 24h Holter and high r...
Objetivo - Descrever casos de cardite reumática com aspecto ecocardiográfico de prolapso ou ruptura de cordoalha da mitral. Métodos - foram estudados 16 casos de cardite aguda (entre 5 e 15 anos), sendo que em 10 havia aspecto de prolapso mitral (grupo 2). As medidas das cordoalhas anteriores e anéis...
A insuficiência mitral crônica, em nosso meio, geralmente é determinada pela doença reumática, doença coronária ou prolapso mitral. Atençäo cuidadosa deve ser dada a estes pacientes, já que eles deterioram silenciosamente. Considerando-se como elemento maior na indicaçäo cirúrgica o reconhec...
PURPOSE--To verify if systolic bulging of floppy mitral cusps can to elastic behavior of their myxomatous collagen tissue. METHODS--Five hearts with floppy mitral valves obtained from autopsies were distended with air (20 to 250 mmHg) through a catheter connected to the left ventricle. It was observed if...
PURPOSE--To verify whether accentuated reductions of left ventricular volume lead to mitral valve prolapse. METHODS--Seven mongrel dogs were bled through the internal jugular vein, the systolic systemic pressure being kept between 100 and 140 mmHg by means of continuous infusion of dopamine; the inferior...
PURPOSE--To compare the patterns of valvar dynamics expressed by the mitral prolapse and regurgitation across the valves, between competitive athletes players of distinctive sport modalities, and between these and sedentary control subjects. METHODS--Pulsed and continuous wave non-colour Doppler echocard...
Objetivo - Estudar a funçäo ventricular esquerda pela ecocardiografia modo M de pacientes sintomáticos com prolapso da válvula mitral (PVM) primário, sem insuficiência mitral significante, durante a prova da fenilefrina, antes e após a digitalizaçäo. Métodos - Foram estudados 31 pacientes com P...
