Analysis of left atrioventricular plane movement during diastole in ischemic heart disease.

The aim of the present study was to investigate the properties of diastolic left atrioventricular plane displacement (AVPD) in coronary artery disease (CAD) patients. In 125 patients (mean age 58.7 +/- 13.

Left systolic atrioventricular plane displacement in the assessment of myocardial viability in patients with previous myocardial infarction.

Unlabelled: In order to detect myocardial viability in coronary artery disease patients (CAD) with a previous myocardial infarction and dysfunction of the left ventricle (LV), the reliability of the left atrioventricular plane displacement (LAVPD) during low dose dobutamine stress echocardiography (DSE), was validated. The study population consisted of 70 CAD patients and 35 age and sex matched healthy subjects. From the apical four and two chamber views the LAVPD was recorded and measured by M-mode echocardiography, at four sites corresponding to the septal, lateral, anterior and inferior walls of the LV, prior and during the DSE (5-10 micrograms/kg/min).

Posterior right diagonal artery.

Background: There is general confusion about a branch of the posterior segment of the right coronary artery that has been referred to as 1) the lower trunk of a divided right coronary artery; 2) a posterior reflection of the right marginal artery; 3) the ramus lateralis; and 4) a posterolateral branch or a posterior descending artery.

Materials: Three hundred human hearts were studied by direct observation, X-ray films, and corrosion casting.

Results: This branch of the right coronary artery arises either after the right marginal artery (in 84% of hearts) or it constitutes the continuation of this artery in the remaining 16%.
