title: [Spontaneous rupture of the papillary muscle with angiographically normal coronary vessels].
abstract: Papillary muscle rupture is an unusual pathology, commonly being a mechanical complication of an acute myocardial infarction or a blunt chest trauma. In this case report we describe a patient with a spontaneous complete posteromedial papillary muscle rupture, secondary to an isolated papillary muscle infarction, in the absence of coronary artery disease, resulting in severe mitral regurgitation, cardiogenic shock and uneventful urgent mitral valve replacement. The clinical and histopathologic literature, and mechanisms to explain this kind of rupture, are reviewed.
