Abstract:
Left ventricular function has been measured in calves before and after the production of a myocardial infarct by ligation of the anterior descending coronary artery. In 20 animals function was measured after the area of the acute infarct had been excised and the left ventricle repaired by direct suture. Infarcts equal to 20% of the left ventricle were found to impair left ventricular function, and significant immediate improvement in function was measured in one-third of the animals in which an infarct was resected.
