Caseous calcification of the mitral annulus: case report
We present a rare case of probable caseous calcification of the mitral. This pathology is more frequently detected in asymptomatic women older than 70 years. To recognize this image is important because echocardiography is the easiest way to elucidate this diagnosis, and more importantly because this structure could be easily misdiagnosed as tumors, thrombus and vegetations, which are much more common. Normally, it has a benign evolution, and the correct diagnosis is crucial to avoid unnecessary surgical interventions.
Assessing prognosis of pulmonary embolism using tissue-Doppler echocardiography and brain natriuretic peptide
Objective:To assess prognosis of pulmonary thromboembolism using tissue Doppler echocardiography and brain natriuretic peptide.METHODS:Patients aged over 18 years were evaluated within 24 hours of confirmed diagnosis (chest tomography/pulmonary scintigraphy) of pulmonary embolism using two-dimensional echocardiography and tissue Doppler for right ventricular systolic (s’) velocities, strain, tissue tracking and myocardial performance index. Plasma brain natriuretic peptide was also obtained within 24 hour. The influence of echocardiographic and clinical variables on mortality was examined (up to 12 months) using Cox regression analysis.RESULTS:Out […]
Exercise-induced ventricular arrhythmias: analysis of predictive factors in a population with sleep disorders
ABSTRACTObjective:To assess the prevalence of ventricular arrhythmias induced by exercise in a population with sleep disorders and to analyze the triggering factors.Methods:Patients were consecutively selected from the database of the Sleep Clinic of Universidade Federal de São Paulo. All subjects were submitted to basal polysomnography, blood sample collection, physical examination, 12-lead ECG, spirometry, cardiorespiratory exercise study on a treadmill, and echocardiogram. The Control Group was matched for age and gender.Results:A total of 312 patients were analyzed. Exercise-induced ventricular arrhythmia was […]
