[Myocardial infarct complicated by cardiogenic shock due to acute mitral insufficiency: the diagnosis of papillary muscle rupture by transesophageal echo].

We describe a case of a man with acute myocardial infarction of the inferior wall complicated by cardiogenic shock due to acute mitral regurgitation. Transesophageal echocardiography showed the rupture of the posteromedial papillary muscle. The examination (otherwise difficult) was facilitated by the mechanical ventilation by means of an endotracheal intubation.
