Rupture of both left ventricular papillary muscles following acute myocardial infarction.
A 77-year-old woman collapsed shortly after arrival at the emergency department and attempts at resuscitation were unsuccessful. Autopsy revealed an evolving recent transmural myocardial infarct in the posterolateral free wall of the left ventricle with rupture of both papillary muscles. No well documented description of post infarction dual papillary muscle rupture was found in the literature.
