Abstract

Single coronary artery (SCA) is a rare congenital anomaly which occurs in a structurally normal heart. We came across a patient presenting with typical angina radiating to left shoulder. Past history was unremarkable. Electrocardiogram (ECG) showed features of lateral wall myocardial infarction. Conventional angiogram (CAG) revealed a SCA (resembling Type R-III)1 supplying the entire myocardium with insignificant lesion in the distal half of right coronary artery (RCA). Cardiac computed tomography (CT) was done which confirmed the presence of SCA originating high above the right sinus of Valsalva. Conservative management was planned.
