An 11 year old boy came in with a 6 months history of intermittent chest pain and a cardiac murmur.An echocardiogram showed a mitral valve mass and mild insufficiency.He underwent an extensive resection of the mitral valve and its papillary muscles,since it was attached to them.A prosthetic mitral valve was implanted.The pathological report was mitral valve myxoma.This type of tumor is unusual during infancy,its location is seldom described,although benign in nature it is potentially fatal.
