Abstract
A 70-year-old woman with acute myocardial infarction (AMI) had a narrow necked left ventricular (LV) aneurysm and pericardial effusion. Although there had been no obvious sign of pseudoaneurysm at the first operation on the 13th day after onset, LV volume increased so dramatically that dyspnea on mild exertion was induced only 2 months after the onset of AMI. She underwent Dor's operation for the expanded LV aneurysm. The histological findings of the resected tissue, which were fibrotic epicardial lesion with small myocyte islands, indicated a true aneurysm. The ultrasound manifestation of a narrow necked aneurysm with abrupt thinning of the myocardium at the hinge point may be a valuable predictor of free wall rupture in the early phase and severely progressive LV remodeling in the late phase. Such aneurysms need to be considered as high risk.
