Single coronary artery (SCA) is a very rare congenital anomaly, in which the entire coronary system arises from the solitary ostium with the incidence of 0.024%–0.066% in the general population undergoing coronary angiography. It is usually considered a benign entity but may cause chest pain, hemodynamic abnormalities, myocardial ischemia, or sudden cardiac death owing to its course arising between the pulmonary artery and aorta. The diagnosis of congenital coronary artery anomalies is usually made by conventional coronary angiography and very few cases have been reported in the literature. To the best of our knowledge, we report this as a first case, in which successful off-pump coronary artery bypass grafting was done for a SCA system.
