Incidental finding of a large pulmonary valve fibroelastoma: a case report.

Papillary fibroelastoma (PFE) is an uncommon primary neoplasm of cardiac origin. They are solitary neoplasms that historically were an incidental finding at the time of autopsy. With the advent of two-dimensional echocardiography, symptomatic cases have been reported in current literature, thus causing a paradigm shift in the management of these tumors. Although the majority of PFE are benign, because of their potential risk for complication related to embolic and obstructive phenomena, they are now considered hazardous and require tumor excision even in asymptomatic patients. We report a case of an asymptomatic incidental large papillary fibroelastoma within the right ventricular outflow tract.
