Anomalous origin of the right coronary artery (ARCA) from the main pulmonary artery is a rare congenital anomaly, unlike the well-known anomalous origin of the left coronary artery (Bland–White–Garland syndrome) from the pulmonary artery. Since most ARCA cases are diagnosed during childhood, few adult cases have been reported. We describe the case of a patient who demonstrated ventricular arrhythmia and low cardiac function due to ischemic heart disease and an ARCA. Coronary angiography revealed flow from the left coronary artery to the pulmonary artery via an epicardial collateral artery and the right coronary artery. Multidetector-row computed tomography provided a definitive diagnosis of ARCA; the patient underwent surgical revascularization.
