Echocardiographic diagnosis of intraventricular clot.

The literature contains many reports of the echocardiographic findings in left atrial myxoma and clot; however, descriptions of left ventricular thrombus or tumor are rare. We discuss here the echocardiographic findings in a patient with a large apical left ventricular thrombus which was confirmed both angiographically and pathologically. The importance of echocardiographically examining the area below the mitral valve near the apex of the left ventricle, where most of the thrombi are located, is stressed.
