Abstract

Single coronary artery (SCA) is a rare congenital anomaly and commonly associated with other congenital cardiac malformations. Some subgroups of SCA can lead to angina pectoris, acute myocardial infarction, or even sudden cardiac death in the absence of atherosclerosis. An anomalous origin of the right coronary artery, arising from the distal portion of the left circumflex artery, has previously been reported in a few cases. In this article, we report a case of a right coronary artery arising from the distal portion of the left circumflex artery with no other cardiac congenital anomaly.
