[Anomalous origin of the right coronary artery from the pulmonary artery].

The authors report a rare case of the abnormal origin of the right coronary artery from the pulmonary artery, presenting with severe angina. Surgical correction-reimplantation of anomalous origin into the aorta-was carried out. As demonstrated by angiography six months after operation, previously present collaterals to the right coronary artery are no longer visualized, right coronary is patent with filling from aorta. The patient is only mild symptomatic due to diffuse atherosclerotic stenosis of the left coronary artery.
