The utility of transesophageal echocardiography in the management of renal cell carcinoma with intracardiac extension.

The accurate assessment of the distal extent of vena caval invasion of renal cell carcinoma into the hepatic veins, inferior vena cava, and right atrium is critical before surgical resection. We present two cases of renal carcinoma with vena caval extension in which preoperative transesophageal echocardiography accurately assessed tumor extent and guided surgical therapy. The role of transesophageal echocardiography in comparison to other diagnostic modalities is discussed.
