Metastatic Wilms' tumor in the right atrium propagated through the inferior vena cava

A patient with a rare case of cardiac tumor in the right atrium secondary to Wilms' tumor of the right kidney, underwent open heart surgery and removal of the mass was presented. This is the 10th. case of intracardiac tumor secondary to renal malignancy. Careful auscultation of the heart is necessary in patients with malignancy in the kidney to detect the possible right heart metastases through the inferior vena cava. Cardiac symptoms precede the renal manifestations in most cases. Malignant renal metastases to the heart should always be in mind in space occupying masses of the right heart chambers.
