Incidental finding of an asymptomatic pulmonary valve papillary fibroelastoma: A case report

Primary cardiac tumors are rare, but papillary fibroelastoma (PFE) is reportedly the most common form, which usually occurs on the left-side valves of the heart. However, PFE involving the tricuspid and pulmonary valves has also been documented. Although PFE is benign and seldom associated with valvular dysfunction, the associated embolic complications may lead to serious consequences. Most patients with PFE lack specific clinical symptoms and the diagnosis is incidental. Surgical resection is the mainstay treatment for PFE in order to prevent the occurrence of embolic complications. In this report, we present a case of a rare asymptomatic PFE of the pulmonary valve, which was incidentally noted during a routine examination with transthoracic echocardiography (TEE). There was neither valvular dysfunction nor hemodynamic change. The PFE was surgically removed, and the diagnosis was further confirmed with histopathology.
