Noninvasive diagnosis of pseudoaneurysm of the left ventricle.

The echocardiographic, scintigraphic, angiocardiographic and autopsy correlations in a patient with left ventricular pseudoaneurysm are presented. Interruption of the echo of the left ventricular wall and radioisotope image of pseudoaneurysm and its communication channel are demonstrated for the first time. The striking similarity of the radioisotope image to the angiographic image is noted. This study suggests that echocardiography has capability to visualize left ventricular wall defects, such as the perforation seen in this case and radioisotope ventriculography is equivalent to the invasive contrast technique. Both of the methods seem to be safe and specific for the diagnosis of left ventricular pseudoaneurysm.
