Intracardiac metastases, report of three cases.

Three patients with intracardiac metastases are described, diagnosed by means of physical examination, electrocardiography (ECG) and echocardiography. Cardiac involvement of the heart by malignant disease is not uncommon, but intracardiac metastases have only occasionally been reported. There are only a few case reports of metastases to the heart that were diagnosed antemortem, because these are rarely clinically significant. Two of the reported patients had clear physical evidence of cardiac involvement. A third case was diagnosed as the result of an abnormal ECG.
