Single right coronary artery: clinical and angiographic findings with surgical management
G Kafrouni, AH Khan and JL Wolfsen
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.
