Between November, 1981 and July, 1989, 4 patients, 3 male and 1 female patients ranging in age from 36 to 45 years, were operated on for aortic insufficiency associated with uncomplicated annuloaortic ectasia. All patients were in New York Heart Association class III. Two patients had clinical stigmata of the Marfan syndrome. The surgical treatment consisted of. supracoronary replacement of ascending aorta with vascular graft and replacement of the aortic valve in our first case. and composite graft replacement of the ascending aorta and aortic valve with reimplantation of the coronary arteries in subsequent 3 cases. Our first patient developed aneurysm of proximal aorta and pseudoaneurysm of distal aortic anastomosis 5 years postoperatively. One patient among the three patients with Ben-tall operation, died of ventricular fibrillation and myocardial failure during immediate postoperative period. Remaining 2 patients were in NYHA class I with follow-up of 16 months and 20 months respectively.
