Coronary arteriography as a physiologic investigational technique

Abstract

An experimental study was undertaken for the purpose of standardizing techniques of radiographic visualization of the coronary arteries, with the object of clinical application of the techniques. An interesting and unforeseen result of the study was the opportunity afforded to confirm, in the intact animal, many indirect observations and hypotheses regarding coronary arterial flow, mechanics of left ventricular ejection, motion and closure mechanisms of the aortic valve, and drug effects on the coronary arteries.
