Department of Thoracic and Cardiovascular Surgery, Sapporo Medical College Sakuzo Komatsu |
From March, 1961 to March, 1979, 264 aortic valve replacement were performed at this institution. A group consisting of 239 consecutive patients who underwent aortic valve replacement until March, 1976, were selected for the purpose of this study. Among them, 39 had simultaneously repair of mitral lesions, 27 repair of congenital heart diseases and another 6 repair of ascending aortic aneurysms. Valves employed were 12 fabric leaflet valve, 111 Starr-Edwards valve (Models 1000 and 1200), 61 Smeloff-Cutter valve, 48 Wada-Cutter valve and 7 miscellaneous.
Forty patients died within the first month postoperatively. Twelve patients were lost to follow-up. Sixty-five patients died during the follow-up periods between one month and 15 years, the mean follow-up period was 7.2 years.
Then 15-year actuarial survival rate for operative survivors was 60%.
Major late complication were 41 thromboembolism, 9 significant paravalvular leak, 9 bacterial endocarditis etc. The causes of late death were 13 cerebral embolism, 5 myocardial infarction, 11 sudden death etc. Eighty percent of survivors were in N.Y.H.A. Functional Class I or II. The causes of limited activities were 9 sequelal of cerebral embolism and 6 myocardial failure.
Marriages following aortic valve replacement were experienced in 14 males and 13 females.
The data indicate that aortic valve replacement gives a good outlook for the patients with aortic valvular disease, although the ideal substitute should be developed.
