Long-term survival following cardiac rupture with subsequent development of left ventricular pseudoaneurysm.

This report describes a patient who survived rupture of the left ventricular free wall following a myocardial infarction and who then subsequently went on to develop a pseudoaneurysm. The rupture became clinically recognized when the patient developed cardiac tamponade. A large hemopericardium was evacuated by performing a thoracotomy and a pericardiotomy. Although not evident at the time of the initial catheterization, a pseudoaneurysm developed over the ensuing months. The aneurysm was initially recognized by radionuclide angiography and confirmed by left ventricular angiography at a second cardiac catheterization. The aneurysm was successfully resected, and the patient was alive and functioning normally 18 months after rupture and 12 months after aneurysmectomy.
