[Diagnostic difficulties in secondary tumors of the heart].

The authors describe case reports of 2 patients who died from malignant pulmonary neoplasms. In one case, tumor metastasized to the left ventricle myocardium, in the other one, pulmonary tumor invaded the interatrial septum. Clinically, coronary heart disease symptoms with acute manifestations prevailed in both the cases. Based on an analysis of the authors' clinicomorphological findings and reported data a number of the clinical signs were distinguished, enabling one to suspect the presence of secondary heart tumors in cancer patients.
