Abstrakt: Abstract: We are presenting a case of floating left and right atrial formations on an atrial septal defect occluder system (23mm StarFLEX®-Occluder) initially supposed to be thrombotic appositions in a 57-year-old man. The closure was performed on the background of left hemispheric stroke and atrial septal aneurysm (ASA) with patent foramen ovale (PFO). The suspect structures were detected in the 6-month follow-up by transesophageal echocardiography (TEE). The patient underwent a successful surgical explantation of the closure device and closure of the patent foramen ovale (PFO) using a pericardial patch. The pathological evaluation of the biatrial device associated appositions revealed hytrophic heart muscle tissue with perifocal scarring and purulent abscess-forming, granulating and foam-cell including inflammatory foreign body reaction instead of the expected thrombus formation.
