[Clinically unrecognized valvular defects in high age groups].
The study has been based on an autopsy series of 474 unrecognized valvular defects of the left heart in high age groups beyond 65. The series comprised 186 males and 288 females with an average age of 77. The incidence of valvular defects was 4.02%. There was a significantly higher incidence of mitral valve insufficiency than in lower age groups of clinically recognized valvular defects (10.75%). The ratio of mitral insufficiency to the stenosis of the left venous ostium and combined mitral defect with prevalence of stenosis was 1:4. The prevalence of males in the series of isolated stenosis of the left arterial ostium attained only 1.35:1.
