Aortic regurgitation with dilation of ascending aorta and right coronary artery occlusion by a rudimentary aortic cusp

Occlusion of a coronary artery ostium, especially that of the right by an a ortic cusp, is a rare congenital anomaly. We had the experience of dealing with an adult patient with aortic regurgitation due to a rudimentary aortic cusp that also occluded the right coronary ostium. We performed composite graft replacement because the patient also had coexistent dilation of the a scending aorta. Postoperative course was uneventful. (C) 2001 by The Societ y of Thoracic Surgeons.
