title: Cardiac tamponade due to rupture of a subepicardial aneurysm following myocardial infarction.
abstract: A 71-year-old male died of cardiac tamponade due to cardiac rupture 22 days after onset of acute myocardial infarction. Autopsy revealed rupture of an unusual ventricular aneurysm characterized by abrupt interruption of the myocardium, a narrow neck, a thin fibrous outer wall partially showing myocardial fibers, and lack of adhesion between the epicardium and pericardium. A review of the literature revealed that 11 among 32 autopsy cases of false aneurysm showed a similar morphology to the present case, these being classifiable as subepicardial aneurysm.
