[Papillary fibroelastoma of the tricuspid valve with mitral regurgitation].

We report a 64-year-old male patient with papillary fibroelastoma of the tricuspid valve associated with moderate mitral regurgitation. Echocardiography had revealed a 10 x 10 mm tumor attaching to the anterior tricuspid leaflet 3 years before. Because the tumor was enlarged to 19 x 15 mm, we excised it with a part of the anterior tricuspid leaflet, and performed tricuspid and mitral valvoplasty. The histological findings suggested papillary fibroelastoma. The postoperative course was uneventful.
