A right atrial in-growth of renal carcinoma occurs in 1% of cases. A traditional approach to removal of the tumor using cardiopulmonary bypass (CPB) and deep-hypothermic circulatory arrest (DHCA) has been challenged in favor of techniques that allow tumor removal without CPB and DHCA. To the best of the present authors' knowledge, no report has yet been made of an invasion by the tumor of the tricuspid valve leaflets and subvalvular apparatus. The details of such a case are reported herein, where CPB + DHCA was used to completely remove the neoplasm, and to preserve tricuspid valve competence.
