title: Degenerative calcific valvular disease and systolic murmurs in the elderly.
abstract: By use of echocardiographic and radiologic imaging, a prospective study was made of 98 elderly men, 65 to 102 years old, to define degenerative calcific valvular disease (DCVD)--its prevalence, morphologic features, functional significance, and relationship to systolic murmurs in the elderly. DCVD was diagnosed in 74 per cent of the group and murmurs were detected in 55 per cent, the incidences increasing with age. Fibrotic and calcific change of the aortic valve was the most common abnormality, occurring alone or together with alteration of the mitral valve. The murmurs were characteristically early systolic, of low intensity and medium pitch, and heard at more than one area. Of the group with valve degeneration, only 7 per cent was judged to be functionally significant and no more than moderate. It was concluded that DCVD is the cause of most systolic murmurs in the elderly and is usually hemodynamically unimportant. Echocardiographic criteria are important in identifying those subjects with possibly significant valvular dysfunction requiring invasive study.
