Abstract

Bacterial endocarditis, caused mainly by Staphylococcus aureus, was found at autopsy in five patients who had a calcified posterior mitral valve annulus. Clinicopathologic correlation indicates that the infection should be suspected in elderly patients with a calcified mitral annulus, the murmur of mitral insufficiency, fever, anemia, polymorphonuclear leukocytosis and a positive blood culture, regardless of evidence of peripheral embolism or of another disease that could cause the last four features. Pertinent pathologic findings are a calcified mitral valve annulus, vegetations of bacterial endocarditis towards the base of the posterior leaflet associated with leaflet perforation and an annular abscess, and no other valvular disease. The infection may develop on the atrial aspect of a leaflet ulcerated by the calcium mass or may begin on its ventricular aspect, subsequently perforating the leaflet and infecting its atrial surface.
