Cardiac valvular papillary fibroelastoma: a report of 2 cases.

Papillary fibroelastomas are rare cardiac valve tumors with potential for life-threatening complications such as stroke or sudden death. We report 2 cases of papillary fibroelastoma that were found by echocardiography. The 1st tumor arose from the mitral valve in a patient who presented after multiple transient neurologic events. The 2nd tumor arose from the aortic valve and was found incidentally during coronary artery bypass grafting. Both patients underwent successful surgical removal of the tumor.
