A rare association between mitral valve fibroelastoma and myxomatous disease with severe mitral regurgitation.

We report a rare case of association between mitral valve fibroelastoma and myxomatous disease in a patient with long history of asymptomatic myxomatous disease and progressive severe mitral regurgitation. The tumor was an intraoperative transesophageal echocardiographic finding and was confirmed during surgery. The differential diagnosis of the echocardiographic image was infective endocarditis.
