Mitral valve replacement with annuloplasty in a patient with infected mitral annular calcification.

Key Clinical Message: Extensive resection of the infected calcified annulus and the reconstruction with a pericardial patch for the debrided annulus is an effective surgical option for the treatment of infectious endocarditis in patients with mitral annular calcification.

Abstract: A 78-year-old woman was referred to our hospital because of left-sided hemiparesis. During the treatment for cerebral infarction, the patient became feverish and lost consciousness. Transthoracic echocardiography revealed mitral annular calcification and a tumor-like mass on the posterior leaflet despite no findings of mitral regurgitation. She underwent successful mitral valve replacement with debridement of the infected mitral annulus and reconstruction of the posterior annulus (annuloplasty) with bovine pericardium after removal of the mitral annular calcification.
