Papillary fibroelasoma of the tricuspid valve. A: Transesophageal echocardiography (TEE) depicted a nodular mobile structure at the anterior leaflet of the tricuspid valve. B: At higher magnification, TEE demonstrated a slight insufficient tricuspid valve and a tumor diameter of 10 × 11 mm. C: Intraoperative gross photograph of the tumor. D: Histological examination showed complex branching papillary fronds characteristic of papillary fibroelastoma.
