    Abstract:
    105 valve replacements with the Björk-Shiley tilting-disc prosthesis have been performed in 99 patients with an overall mortality of 12%. The hospital mortality for 73 single aortic valve replacements was 10%, for 24 single mitral valve replacements 13%, and for 5 double valve operations 20%. One late death (1%) occurred in a case with single aortic valve replacement. The follow-up period of the first patients with aortic valve replacement is 4 1/2 years, and that of those with mitral valve replacement over 2 1/2 years. The most common late complication in patients with mitral valve replacement was a paravalvular leak (19%), whereas in patients with aortic valve replacement slight haemolytic anaemia (4%) and late thromboembolism (3%) occurred most frequently. 84 of the 87 survivors showed manifest clinical improvement in their preoperative status and increased exercise tolerance.
