  • Title: Anomalous origin of the right coronary artery from the pulmonary artery.
    Author: Lerberg DB, Ogden JA, Zuberbuhler JR, Bahnson HT.
    Journal: Ann Thorac Surg; 1979 Jan; 27(1):87-94. PubMed ID: 453965.
    Abstract:
    Three patients with anomalous origin of the right coronary artery from the pulmonary artery are presented together with a review of the 14 patients with this anomaly previously reported. One of the current patients is the youngest to be diagnosed before operation and the youngest to undergo corrective operation. Although the lesion is usually asymptomatic, it may contribute to sudden death. The only suggestive physical finding is a continuous murmur with diastolic accentuation, which is present only in some patients. There are no diagnostic electrocardiographic or chest roentgenographic changes. Diagnosis is made best by selective left coronary arteriography showing retrograde filling of the right coronary artery from collateral vessels. Operative repair should consist either of direct reimplantation of the proximal right coronary artery into the aortic root or of saphenous vein bypass graft to the coronary artery with ligation of its origin. Operation is recommended when the lesion is recognized.
