Abstract
Coronary artery anomalies occur in 1.3-5.6% of patients undergoing coronary arteriography. An anomalous origin of LCX from right coronary sinus is the most common congenital variant. It is usually considered “benign” since it is not known to predispose individuals to sudden cardiac death. Such vessels are particularly predisposed to atherosclerotic disease in their proximal portion, due to the acute angulation of its origin from the aorta and its posterior retro aortic course. We present a case of 55 years old female admitted with acute coronary syndrome. Coronary angiogram showed the anomalous origin of the left circumflex artery from right coronary sinus. This artery had a significant lesion which was successfully stented with a drug-eluting stent.
