Evolution of a Papillary Fibroelastoma

Abstract Papillary fibroelastoma is a rare primary tumor of the heart usually found incidentally at autopsy. Little is known about the natural history of this tumor, but an aggressive surgical approach is recommended because of the high incidence of embolization. We describe a patient whose tumor was found during transthoracic echocardiography and who had had a normal echo 10 years previously. This finding suggests that papillary fibroelastoma may be an acquired rather than a congenital lesion. (J Am Soc Echocardiogr 1998;11:92-4.)
