title: Late bacterial endocarditis of an amplatzer atrial septal defect occluder device.
abstract: A 66-year-old man with a large secundum atrial septal defect (ASD) that had been repaired percutaneously 30 months previously with an Amplatzer ASD occluder (ASO) presented with fevers and Staphylococcus aureus bacteremia. Transesophageal echocardiography revealed a 1.5 x 1.5 cm mobile mass on the left atrial side of his ASO consistent with a vegetation. When the ASO was explanted, the left atrial side of the device was poorly endothelialized. In conclusion, the present report is the first description of late infective endocarditis in an adult with an ASO.
