Prognosis of surgically treated chronic aortic valve disease. Predictive indicators of early postoperative risk and long-term survival, based on 439 cases.

The study concerns 439 patients having isolated chronic aortic valve disease (248 having pure or predominant calcific stenosis, 65 having stenosis and regurgitation, and 126 having aortic regurgitation). The operations began in 1968, and the survivors have been re-examined every year, with an average follow-up of 44.2 months. Average age at operation was 55 years (range 14 to 78). Patients in the stenosis group were significantly older (59.7 years) than those in the mixed disease group (54.8 years) or the regurgitation group (45.8 years) (p
