The frequency of chronic non‐rheumatic valvular heart disease in Iceland was investigated via autopsies performed from November 1965 through December 1974. During this period, about 12.400 Icelanders died at the age of 16 years and older and 28.8 per cent of these were included in the study. At autopsy, males outnumbered females by 2:1. The frequency of calcific aortic stenosis was found to be 3.63 per cent and the prevalence was calculated to be 3.17 per cent among males and 4.50 per cent among females. Calcific aortic stenosis in tricuspid valves was more frequent in females and calcific aortic stenosis in bicuspid valves was more frequent in males. Among the hearts with calcific aortic stenosis, 70.8 per cent were found to have normally tricuspid valves, 25.4 per cent bicuspid valves and 3.8 per cent tricuspid valves with an unicommissural fusion. In 0.59 per cent of the hearts the aortic valve was either bicuspid or had an unicommisural fusion without the features of calcific stenosis. However, a functional stenosis was suggested by the increased weight of most of these hearts. The frequency of bicuspid aortic valves was 1.2 per cent with a prevalence in males of 1.54 per cent and in females 0.50 per cent. A calcified mitral annulus was found in 1.98 per cent of the hearts and in most, it was either associated with calcific aortic stenosis in a tricuspid valve, or it was a single valvular disease. Rheumatic valvular disease was found in 1.08 per cent of the hearts examined.
