Abstract
Papillary fibroelastoma (PFE) is a rare, often benign, tumor originating typically in the endocardium and valves, with a preference for the left side of the heart. Although PFEs can appear asymptomatic, in the setting of embolization, they can lead to stroke, acute limb ischemia, and/or mesenteric ischemia. Rarely, PFEs can originate from the pulmonary valve, with the potential for embolic showering into the pulmonary artery, leading to potential right-sided heart outflow obstruction. Treatment has been open surgery in most cases, although treatment of right-sided heart masses with extracorporeal circulatory support extraction systems have been described. Recently, large bore suction thrombectomy devices have become available, typically used for cases of venous thromboembolism. In the present report, we describe a case of a symptomatic infected PFE treated by percutaneous suction thrombectomy using the Inari FlowTriever system (Inari Medical).
