Cardiac papillary fibroelastomas, although generally small and asymptomatic, have been suspected of being responsible for cerebral accidents, angina, and sudden death. The diagnosis of tumor embolization, considered in a number of cases, has been based on circumstantial evidence in all instances except for one case of sudden death due to embolism to the left anterior descending coronary artery. In all other cases, angina and sudden death have been related to a ball valve-type obstruction of a coronary ostium by tumor. The present case documents tumor embolism to peripheral right coronary arteries with associated, clinically silent myocardial changes.
