Right ventricular (RV) mass and volume calculations are important correlates of survival in patients with pulmonary arterial hypertension (PAH). We tested the hypothesis that RV mass, volumes and function could be measured accurately with real-time three-dimensional echocardiography (3DE) in patients with PAH and compared those against cardiac magnetic resonance (CMR). ...

INTRODUCTION: Conventional echocardiography is often inconclusive for the presence or the absence of left ventricular (LV) thrombus. Contrast echocardiography could have additional diagnostic and therapeutic significance. This analysis investigated the value of contrast echocardiography for LV thrombus detection in patients postinfarction and the impact on choice of antithrombotic therapy. METHODS: ...

Left ventricular (LV) ejection fraction (EF) was known as a conventional predictor of heart failure (HF). However, early transmitral flow velocity (E)/early diastolic velocity of mitral annulus (E') correlated well with LV end-diastolic pressure, and E/E' ratio >15 was an excellent predictor of adverse outcomes in patients with HF. This ...
