title: Papillary elastofibroma of the left ventricular septum.
abstract: Papillary elastofibromas of the heart are usually incidental findings at autopsy. They occur more commonly on the surfaces of the valves than on the mural endothelium and are characterized by a papillary configuration with fronds composed of a collagenous and elastic tissue core lined by hyperplastic endothelial cells. Echocardiography and cardiac catherization demonstrated the lesion preoperatively in this case.
