Aortic stenosis is the most common valvular disease in the adult population. A significant aortic stenosis is a serious condition, and if a symptomatic patient is not operated on, it may in most cases cause death. We have examined how many aortic stenoses that were diagnosed during one year, and a follow-up of the patients was also performed. We found 77 patients with significant aortic stenosis with a mean age of 76±13 years. At the time of follow-up 30 (39%) patients, aged between 29-85 years, had been surgically treated with implantation of a valve prosthesis within 2-23 months after the initial examination. At this initial examination 14 of the 30 patients who later underwent surgery had no symptoms. A coronary bypass operation was also performed on seven patients. Postoperative complications were observed in six patients, but none of them was fatal. At the initial examinations there were 26 (34%) patients with a significant aortic stenosis and symptoms who were not treated surgically. The main reason why these patients were not operated was high age, unwillingness, or severe left ventricular dysfunction. This study indicates the importance of repeated clinical and echocardiograpic examinations in patients with aortic stenosis. Almost half of the patients, that later underwent surgery, had no symptoms at the initial examin...
