Coronary artery anomalies (CCAs) are a group of congenital conditions characterized by abnormal origin or course. Coronary artery bypass graft (CABG) surgery in this single coronary artery (SCA) is rarely reported. In this case, A 41-year-old male patient presented with exertional dyspnea and productive cough. The echocardiogram showed a moderately dilated left ventricular (LV) with mild LV systolic impairment and coronary angiography (CAG) revealed the left main coronary artery arises from the right coronary ostium with the right coronary artery. In addition, occlusion in right coronary mid-portion and distal circumflex and moderate to severe stenosis in proximal left anterior descending artery was identified. Considering the significant atherosclerosis and the subpulmonic course of this SCA, CABG with sequential anastomosis of saphenous vein was performed. Postoperatively, he made good progress and was discharged day 6 after surgery without any complication.
