[Right coronary artery arising from the pulmonary artery. Surgical treatment].

The authors report the case of an anomalous right coronary artery arising from the pulmonary artery. The patient was an active 18 years old boy who had a continuous murmur with diastolic accentuation, the cause of which was determined at angiography. There were electrical and echocardiographic signs of moderate left ventricular dilatation and thallium scintigraphy showed a myocardial perfusion defect. These were the only detectable consequences of this rare malformation. Normal coronary circulation was reestablished surgically, the indication being the risk of sudden death which has been previously reported rather than acute myocardial ischemia.
