Cardiac papillary fibroelastoma can rarely originate from the mitral valve chordae and can be successfully managed with surgical excision without requiring valve repair.
Rare chordal papillary fibroelastoma may permit valve-sparing excision; extends sparse case literature on atypical valvular origins.
Cardiac papillary fibroelastoma (CPF) is a rare benign primary cardiac neoplasm. In particular, CPF originating from the mitral valve chordae is extremely rare. A 74-year-old man was hospitalized for the evaluation of a cardiac mass in the left ventricle. Echocardiography revealed a mobile, spherical, pedunculated 2.1×2.1 cm mass at the mitral valve chordae with no mitral regurgitation. The patient underwent excision of the mass without repairing the mitral valve. A histological examination confirmed the mass to be a papillary fibroelastoma.
