## Abstract Four patients with left atrial myxoma were studied using high speed B mode echocardiography with a mechanical sector scanning system. In all four patients, a mass of echoes was recognized in the left atrial chamber during systole. Its lower portion protruded into the left ventricle thro

Abstract
This paper describes two cases of left ventricular aneurysm following myocardial infarction by real time B mode echocardiography with a mechanical sector scan. The most distinctive feature was the paradoxical movement of the aneurysmal wall; in systole, it moved posteriorly to form a bulge, whereas the remaining noninfarcted area was oriented toward the left ventricular cavity in contraction. The final diagnosis was verified by aneurysmectomy.

## Abstract ## Purpose Realβtime 3βdimensional transthoracic echocardiography (RTβ3DβTE) with realβtime volume rendering (RTVR) offers multiple simultaneous views and spatial definition of intracardiac structures superior to that attainable by 2βdimensional transthoracic echocardiography (2DβTE).
## Abstract We examined interobserver and intrapatient variations in M mode echocardiographic measurements of diastolic and systolic interventricular septal and left ventricular posterior wall thickness and in the calculated percent systolic thickening of both walls. Diastolic measurements were mad
