Paper Abstract

Several indices of left ventricular systolic performance have been proposed, one of which, left ventricular ejection fraction, has been extensively applied to clinical problems of patients with heart disease. Left ventricular ejection fraction, which is the ratio of left ventricular stroke volume to end-diastolic volume, is usually performed by left heart catheterization with contrast ventriculography. Catheterization ordinarily requires hospitalization, is relatively expensive and has a definite, although low, morbidity and mortality. In particular contrast ventriculography does not lend itself to serial study at frequent intervals. Consequently several radionuclide methods have been developed which accurately measure left ventricular ejection fraction. In these methods an Anger scintillation camera is used with 99mTechnetium to record either an electrocardiographically gated (1) or a dynamic radionuclide angiocardiogram (2)(3).
