Pulmonary valve papillary fibroelastoma: Management of an unusual, tricky pathology

Abstract

Papillary fibroelastomas are rare benign tumours of the endocardium, accounting for the most common primary valvular tumours of the heart. They typically originate from left-sided heart valves, whereas pulmonary valve involvement is anecdotal. They rarely cause valvular dysfunction, but they can cause turbulent flow and thrombus formation with consequent cerebral, retinal, coronary and pulmonary embolic disease and obstruction. We present here the case of a 56-year old man who was referred to our institution with an accidental finding, at transthoracic echocardiogram, of a mobile, pedunculated mass on the pulmonary valve, confirmed at cardiac magnetic resonance. He underwent surgical removal of the mass through median sternotomy with complete sparing of the valve. The postoperative course was unremarkable. Histopathological examination confirmed that the mass was a papillary fibroelastoma. © 2012 The Author.
