Cardiac metastasis due to pulmonary metastasis from a transitional cell carcinoma.

We report a rare case of symptomatic cardiac metastasis from a transitional cell carcinoma of the renal pelvis diagnosed by echocardiography. A 75-year-old patient with a long history of neoplasm since 1999 and coronary artery disease with CABG in 2003, was admitted to our department. He underwent cardiac surgery using cardiopulmonary bypass with tumor excision. Histologically it was the same type of transitional cell neoplasm which was operated seven years before. We present all medical history, detailed 2D and 3D echocardiography, intraoperative pictures and discuss possible chain of changes from renal pelvis cancer to clinical manifestation of cardiac mass. There is proved a rapid progression of cardiac tumor with clinical manifestation few months after control TEE examination without any evidence of cardiac mass. It is important that this is a very rare case of left heart metastasis from right side of circulatory system through pulmonary stage of cancer progression.
