  • Title: Cardiac pseudoaneurysm coupled with a rupture of the papillary muscle complicating myocardial infarction.
    Author: Harada T, Ida T, Takano T.
    Journal: Acta Cardiol; 2002 Dec; 57(6):435-7. PubMed ID: 12542123.
    Abstract:
    As a complication of myocardial infarction, dual rupture of the left ventricular myocardium and the papillary muscle is a rare condition. In such a case, the heart is predisposed to reduced output because of unloading of the ventricle during systole, resulting in the patient being in danger of deteriorating into a severe state or dying suddenly from cardiogenic shock. We report a rescued case of a 65-year-old woman, who had cardiogenic shock due to left ventricular pseudoaneurysm, coupled with partial rupture of the posteromedial papillary muscle three weeks after posterior myocardial infarction. Emergent left ventriculography revealed a large aneurysmal cavity and regurgitation towards the left atrium. The patient underwent emergent aneurysmectomy with mitral valve replacement.
