      Abstract

      Papillary muscle rupture (PMR) is a life-threatening cardiac emergency that is generally associated with inadequate myocardial perfusion after acute myocardial infarction. Nonischemic spontaneous PMR occurs less frequently and is mostly caused by myocarditis, infections, or trauma. We report a patient with spontaneous PMR resulting in severe mitral regurgitation with refractory heart failure showing no specific causes but deterioration of the mitral leaflet and papillary muscle. The integration of pathologic and echocardiographic findings describes the details of the disease.
