title: Anomalous origin of the right coronary artery from the ascending aorta. Diagnosis by digital subtraction angiography.
abstract: The anomalous origin of a coronary artery often poses diagnostic difficulties at angiography. The right coronary artery is more rarely affected than the left. A patient is presented in whom the right coronary artery arose from the ascending aorta. The diagnosis of this rare anomaly was facilitated by the use of digital subtraction aortography and allowed selective angiography of the artery with an appropriately shaped catheter.
