Papillary fibroelastoma of mitral papillary chordae in a young patient

Our case is a 38-year-old man, admitted to Cardiology Department with shortness of breath. Echocardiography yields a hyperechogenic mass localized to papillary muscle with severe mitral regurgitation. Coronary angiography demonstrated radiopacity localized to the papillary muscle. The excision of the mass was consistent with elastic tumor, which was reported as papillary fibroelastoma attached to the papillary chordae of the mitral valve. A 29 no St-Jude bileaflet mechanical valve was implanted to mitral position. Papillary fibroelastoma (PF) can be found in young age and originate from the papillary muscle, which the radiopaque angiographic appearance of the mass supports the diagnosis.
