Patch repair of postinfarction pseudo- and subepicardial aneurysm of the left ventricle.
Left ventricular pseudo-aneurysm and subepicardial aneurysm are rare complications of myocardial infarction. However, the prognosis of medical treatment is extremely poor and the operative procedure is controversial. We experienced 3 consecutive patients with this unusual left ventricular aneurysm, and described the clinical presentation, operative procedure and its result in these patients. The interval from myocardial infarction to discovering aneurysmal formation is short. The term was within a month. In all patients, the papillary muscle was in the proximity of the orifice of the aneurysm. Patch repair of these unusual left ventricular aneurysms may be effective for improvement of left ventricular function without mitral regurgitation.
