[Atresia of the right coronary ostium associated with annulo-aortic ectasia--a case of successful surgical repair].
A case of a 51-year-old male with atresia of the right coronary artery and annulo-aortic ectasia is described. He presented with heart failure and underwent open-heart surgery. Preoperative aortography did not show the ostium of the right coronary artery. At surgery the right coronary ostium was not found on the intimal surface of the aneurismal aortic wall. A fine cord was attached to the adventitial surface of the anterior aortic root. A modified Bentall's procedure was performed to reconstruct the left coronary artery alone. The post-operative course was uneventful. It is speculated that the hypoplastic ostium of the right coronary artery was pulled up and formed a flap-like closure with increased expansion of the aorta.
