Abstract: Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly. Although asymptomatic in most cases, with the anomaly only being detected incidentally, surgical correction should be considered before onset of severe myocardial ischemia in such cases. Here, we present a 70-year-old man who was referred to our department due to chest pain on effort and was given a diagnosis of ARCAPA concomitant with mild aortic stenosis. As the symptoms and the degree of aortic stenosis deteriorated during follow-up, the patient underwent direct re-implantation of the right coronary artery into the ascending aorta and aortic valve replacement. The patient's postoperative course was uneventful, and the symptoms disappeared. Postoperative myocardial perfusion scintigraphy revealed improvement of the myocardial ischemic area.
