Single coronary artery is a rare congenital anomaly. It has a single ostia arising from the aorta and gives rise to the whole coronary circulation. We reported a case of a single right coronary artery (RCA) with the left main coronary artery (LM) arising from the proximal RCA, and its proximal transfer branch was between the aorta and the pulmonary artery with a transseptal course of the middle to distal LM. In view of the aforementioned orientation, it was considered R-II C type in the modified Lipton's classification. Due to persistent chest pain, the patient underwent coronary artery bypass graft (CABG) from the left internal mammary artery to the first diagonal branch. The patient had symptom relief after CABG surgery.
