Echocardiographic-cineangiographic correlation in detecting left ventricular aneurysm: a prospective study of 422...

Four hundred twenty-two consecutive patients with a documented myocardial infarction underwent cardiac catheterization and echocardiographic examination. Adequate two dimensional echocardiograms were obtained in 386 patients (91 percent). Left ventricular aneurysm was defined echocardiographically and cineangiographically as a well demarcated bulge in the contour of the left ventricular wall during both diastole and systole, demonstrating dyskinesia or akinesia. Cineangiography was considered as the standard for the diagnosis of left ventricular aneurysm. The site of aneurysm was mainly anteroapical. An aneurysm was judged present on cineangiography in 111 patients and on echocardiography in 118 patients. The presence and absence of an aneurysm echocardiographically correlated in 103 and 260 patients, respectively, with cineangiography. In 8 patients a cineangiographically identified aneurysm was not manifested echocardiographically, whereas in 15 patients an aneurysm identified on echocardiography was not evident on cineangiography. Thus two dimensional echocardiography can detect or exclude a left ventricular aneurysm with a high level of sensitivity (93 percent) and specificity (94 percent).
