Cardiac tumor consecutive from the arteria renalis level was admitted by computed tomography (CT) and magnetic resonance imaging (MRI). It flows to the right ventricle at the diastolic phase. The emergency surgery was enforced for the prevention of pulmonary embolism and haemodynamic sustain. The atrial tumor was resected under cardiopulmonary bypass. However, it was difficult to resect completely tumor in the inferior vena cava (IVC), because of infiltration to the wall of IVC. The pathological findings was clear cell carcinoma, so-called renal cell carcinoma. Interferon (IFN) therapy was continued after the operation.
