False left-ventricular aneurysm: Diagnosis by noninvasive means

With the advent of noninvasive diagnostic tests, there has been an increase in the number of reports of false left ventricle (LV) aneurysm. This suggests that this type of aneurysm, which may result in cardiac rupture, may be more common than is generally appreciated. Earlier recognition will undoubtedly lead more frequently to prompt surgical repair. At the present time, radiographic and radiotracer criteria clearly distinguish true from false LV aneurysm. With a diagnosis of false LV aneurysm, there is a clear indication for cardiac catheterization. Coronary angiography is especially important to identify lesions requiring bypass grafting. Precise anatomic definition of the false LV aneurysm is also achieved. With this information, surgical planning can be done before rupture of the false aneurysm. In centers with expertise in echocardiography, a pre-angiographic diagnosis of false LV aneurysm is possible. However, the radionuclide study appears to provide more information. From observations, it appears at the present time that chest radiographs and radionuclide procedures reliable reveal true LV aneurysm and allow prompt diagnosis of false LV aneurysm.
