title: Single right coronary artery: clinical and angiographic findings with surgical management.
abstract: Sudden death, myocardial infarction, and anginal syndrome have occurred in patients with single right coronary artery even in the absence of occlusive arteriosclerotic disease. We are reporting the case of a patient with this anomaly without concomitant arteriosclerotic involvement who was managed surgically. A 46-year-old woman was seen with disabling angina of 8 months' duration. Coronary arteriography established the diagnosis of a single right coronary artery. An aorta-anterior descending saphenous vein bypass graft was performed, and the patient remains asymptomatic 29 months postoperatively. Single right coronary artery is a rare anomaly, and its recognition as a potentially dangerous lesion is essential for the prompt and proper care of patients.
