Abstract
Echocardiography showed a large anterior chamber communicating with the left ventricular cavity through the interventricular septum in a patient with a previous left ventricular aneurysmectomy. At postmortem examination this chamber proved to be an 11-cm diameter pseudoaneurysm that opened into the left ventricle through a 3-cm orifice. A review of the literature showed 67 cases of histologically proven left ventricular pseudoaneurysm, most of which occurred after myocardial infarction and cardiac surgery. Twenty-six of 32 left ventricular pseudoaneurysms were successfully operated upon. Among 35 patients with pseudoaneurysms not operated upon, rupture was a cause of death in 11.
