Coronary artery bypass graft in an isolated single coronary ostium with triple vessel disease

Abstract

Abstract Single coronary artery (SCA) is a rare congenital anomaly whereby only one coronary artery arises from single coronary artery ostium of the aortic trunk and supplies the whole heart. The incidence of this anomaly is 0.0024–0.066% in patients undergoing coronary angiography. It is usually an isolated anomaly and majority of patients are picked up incidentally. Lipton classification is widely used to classify this anomaly. Most cases are detected by computerized tomography and/or coronary angiography and are treated medically. Here, we present a rare case of type RII-B in which the patient underwent coronary artery bypass graft for severe triple vessel disease presenting as acute myocardial infarction.
