Third Coronary Artery Observed in a South Indian Male Cadaver: a Case Report

Abstract

We present a case of third coronary artery arising directly from the anterior aortic sinus of Valsalva in a 60 year old male cadaver. It coursed in the epicardium downward, forward and to left on the sternocostal surface of the right ventricle up to the apex of heart where it anastomosed with left anterior descending artery. During its course it gave small ventricular branches to the right and left ventricles. Clinical importance and embryology of the variation are discussed.
