Abstract

Angiocardiograms have been widely used to calculate volumes of cardiac chambers. By determining the left ventricular volume in end-diastole and end-systole the ejection fraction can be calculated. The ejection fraction is considered a clinically useful index of left ventricular function and is widely used in the preoperative evaluation of patients with cardiac disease.
