title: Cardiac pseudoaneurysm caused by mitral ring calcification.
abstract: A case of left ventricular pseudoaneurysm caused by mitral ring calcification (MRC) in a 71-year-old woman is reported. MRC was initially detected by two-dimensional echocardiography. Two months later, rupture of the posterior wall and pseudoaneurysm formation were diagnosed. Mitral value replacement and reconstructive surgery of the myocardial wall were performed. The patient died 46 days after the operation. At autopsy, there was no histopathological evidence of myocardial infarction, infective endocarditis, or other conditions affecting the cardiac endomyocardium. Pseudoaneurysm apparently resulted from left atrial and ventricular tears caused by MRC.
