Case Reports Left Circumflex Artery Arising as a Terminal Extension of the Right Coronary Artery

We found two patients with anomalous origin of coronary arteries among 450 patients who underwent coronary angiography at our clinic. The case presented herein is a rare anomaly in which the circumflex coronary artery arises as a terminal extension of the right coronary artery. The main stem and obtuse branches of the artery were normal and well-developed. The patient was a 64-year-old man who was mainly suffering from intermittent claudication of his left leg, and the coronary anomaly was asymptomatic.
