Surgery of aortic stenosis and lesions of the ascending aorta.

Between 1978 and 1986, 442 aortic valvular replacements were performed for chronic calcified aortic stenosis. In 11 patients (2.5%, seven men and four women) replacement of the ascending aorta was associated with the valvular replacement, because of: seven supra-coronary aneurysms, two aneurysms involving the Valsalva sinuses, and two acute dissections of the ascending aorta. The repair of the ascending aorta consisted in inserting: one patch on one Valsalva sinus, seven supra coronary Dacron prostheses, three valved conduits (according to the Bentall technique). One patient died postoperatively (9%).
