Secondary neoplastic infiltration of the myocardium diagnosed by two-dimensional echocardiography in seven cases with anatomic confirmation.

ABSTRACT

In seven patients with different types of neoplasm, secondary myocardial infiltration was diagnosed in vivo by two-dimensional echocardiography and confirmed by direct inspection. In all patients, clinical and electrocardiographic findings were suggestive but nonspecific for myocardial involvement. Two patients had cardiac tamponade and three had pericardial effusion. In three patients, the echocardiographic diagnosis made it possible to plan specific therapy. Clinical, electrocardiographic and echocardiographic aspects are discussed. A two-dimensional echocardiographic examination should be performed in all patients when cardiac metastatic involvement is suspected from clinical electrocardiographic findings, because the in vivo diagnosis of such a condition may have important therapeutic implications for such patients.
