Unusual Locations for Cardiac Papillary Fibroelastomas

Papillary fibroelastomas (PFEs) are rare and benign cardiac tumors which usually are localized on the valves (mostly on the aortic valve), though they may originate also from the ventricles or atrial walls. Whilst, in the large majority of cases, these lesions are asymptomatic they may cause serious complications such as thromboembolic events, or more rarely valvular dysfunctions. Surgical excision is necessary for a symptomatic lesion. The management of asymptomatic lesions is not defined. Herein are reported the details of a miniseries of six cases operated on at the authors' institution between 2005 and 2015. A review of the current literature suggests that PFE is a rare but potentially treatable cause of thromboembolic events, and must be borne in mind during the differential diagnosis of cardioembolic stroke. The surgical excision of PFEs is safe and definitive.
