To study endocardial wall motion and thickness as indexes of infarction, we used two-dimensional echocardiography to examine regional percentages of systolic wall thickening (%Th) and endocardial motion (%EM) in infarcted canine hearts. Thirteen dogs were studied 48 hours after occlusion of the circumflex or left anterior descending coronary artery. Two-dimensional echocardiographic cross sections obtained every 16 msec at 1-cm intervals from apex to base in an open-chest, anesthetized… CONTINUE READING
