Aortic Valve Replacement and Concomitant Coronary Artery Bypass Grafting in a Patient with Infective Endocarditis and Anomalous Origin of the Right Coronary Artery from the Opposite Sinus of Valsalva

Abstract

A 69-yrs-old woman with anomalous origin of the right coronary artery from the opposite sinus of Valsalva (ACAOS) was diagnosed as having infective endocarditis affecting the aortic valve. Transthoracic echocardiography showed severe aortic stenosis and vegetations on the cusp of the aortic valve, which necessitated aortic valve replacement. Before the operation, computed tomography showed a right-ACAOS, with the artery running an interarterial course between the aorta and pulmonary artery. ACAOS running an interarterial course has been reported to be associated with an increased risk of ischemic cardiac events and sudden death. The patient was treated successfully by the aortic valve replacement with concurrent coronary artery bypass grafting using a saphenous vein graft for the right coronary artery.
