Survival following free rupture of left ventricular aneurysm: report of a case

A 50-year-old man sustained free rupture of the left ventricle four weeks following a massive anterior myocardial infarction. The rupture occurred at the junction between a bulging left ventricular aneurysm that was not yet fibrotic and normal myocardium without evidence of fresh myocardial infarction. Accurate preoperative diagnosis aided by echocardiography and right heart catheterization made possible a planned surgical approach. Postoperative support with intraaortic balloon pumping appeared to be beneficial in maintaining statisfactory cardiac function until an adequate stroke volume could be reestablished, presumably by an increase in left ventricular volume.
