Right Ventricular Systolic Function After the Cone Procedure for Ebstein's Anomaly: Comparison Between Echocardiography and Cardiac Magnetic Resonance.

Although the Cone procedure has improved outcomes for patients with Ebstein´s anomaly (EA), neither RV systolic function recovery in long-term follow-up nor the best echocardiographic parameters to assess RV function are well established. Thus, we evaluated RV performance after the Cone procedure comparing two-dimensional (2DEcho) and three-dimensional (3DEcho) echocardiography to cardiac magnetic resonance (CMR). We assessed 27 EA patients after the Cone procedure (53% female, median age of 20 years at the procedure, median post-operative follow-up duration of 8 years).

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.

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.

Simplified single plane echocardiography is comparable to conventional biplane two-dimensional echocardiography in the evaluation of left atrial volume: a study validated by three-dimensional echocardiography in 143 individuals.

The left atrial volume index (LAVI) is a biomarker of diastolic dysfunction and a predictor of cardiovascular events. Three-dimensional echocardiography (3DE) is highly accurate for LAVI measurements but is not widely available. Furthermore, biplane two-dimensional echocardiography (B2DE) may occasionally not be feasible due to a suboptimal two-chamber apical view.

Exercise-induced ventricular arrhythmias: analysis of predictive factors in a population with sleep disorders.

Objective: 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.
