Papillary fibroelastoma arising from the pulmonary valve associated with pulmonary embolization.

Cardiac papillary fibroelastomas are rare, usuallybenign tumors that can be detected at autopsy, during open-heart surgery, or with echocardiography. They usually arise from the cardiac valves and more commonly are found on the left side of the heart. Embolization of left-sided and tricuspid valve tumors has been well documented. This is the 1st reported case of pulmonary embolization of a papillary fibroelastoma arising from the pulmonary valve.
