[Radionuclide ventriculography in the diagnosis of a postinfarct aneurysm and the evaluation of its impact on left ventricular function].

This is a report on thirty-four patients subjected to radionuclide ventriculography because of suspected post-infarction aneurysm. To discover eventual kinetic disorders, apart from visual assessment of the wall kinetics, amplitude-phase analysis is also employed. The sensitivity of the method is compared with that of bi-dimensional echocardiography. The assessment of post-infarction left ventricular function by either of the methods is also compared. A correlation is established between left ventricular area involved by kinetic disorders, and reduction of the radionuclide total ejection fraction. The values of the latter, estimated echocardiographically, are consistently elevated.
