shu-508 and Aneurysm--False

The diagnosis of left ventricular pseudoaneurysm after acute myocardial infarction is usually based on echocardiography. However, this technique may have limitations in some patients, especially in cases with suboptimal acoustic window. The objective of this study was to evaluate the usefulness of contrast echocardiography in the diagnosis of left ventricular pseudoaneurysm after myocardial infarction.. The study population comprises six patients in whom a two-dimensional echocardiography showed an image consistent with left ventricular pseudoaneurysm. Levovist (Schering) 4gr was administered i.v. to more clearly visualize the blood flow from the left ventricle to the left ventricular pseudoaneurysm cavity in all patients. Infarct location was anterior in five patients, and posterolateral in one. No patient had received thrombolysis or primary angioplasty during the acute phase. The transthoracic echocardiographic study showed an echo-free space adjacent to left ventricle in all patients. In four cases, the diagnosis of left ventricular pseudoaneurysm was made before contrast administration. In the remaining two patients, the definite diagnosis was made only after Levovist administration.. In the diagnosis of postinfarction left ventricular pseudoaneurysm, the administration of contrast agents may be of help in the correct visualization of the blood flow from the left ventricle to the left ventricular pseudoaneurysm cavity, and may allow a definite diagnosis to be obtained in some patients.
