Papillary fibroelastoma is a rare cardiac tumor usually discovered incidentally during autopsy or cardiac surgery. Severe aortic regurgitation and a papillary fibroelastoma on the right coronary cusp were found in a 54-year-old man who had been referred to this institution for further examination for heart murmur. A two-dimensional echocardiogram showed a fluttering, mobil, and pedunculated mass attached to the right coronary cusp of the aortic valve; moreover, a color Doppler echocardiogram revealed a severe aortic regurgitant flow inclined to the anterior leaflet of the mitral valve. A frond-like tumor (5 mm×5 mm) attached to the right coronary cusp of the aortic valve was discovered during surgery. This tumor had the typical hitologic characteristics of a papillary fibroelastoma.
