Abstract:
Differential diagnosis of a so-called false aneurysm of the left ventricle from the true type after a myocardial infarction is important because the risk of rupture of the false aneurysm is high. Two cases of ventricular aneurysms with false type-like shape underwent surgical repair. Preoperative left ventriculography in Case 1 (male, 77) showed an aneurysm of 40×40×35mm in size with a narrow neck at the postero-inferior wall. The aneurysm of Case 2 (male, 61) was 20×20×10mm in size with a narrow neck at the inferior wall. These ventriculographic findings suggested a false type of aneurysm, but operative findings and pathological examination revealed that these were“true”aneurysms in which wall myocardial cells were observed. Left ventriculography and echocardiography were not sufficient to differentiate false left ventricular aneurysm from true aneurysm, particularly at the posterior and inferior wall.
