On (b)(6), 2013, a 25mm amplatzer cribriform occluder (aco) was implanted to close two atrial septal defects (asd) approximately 5mm apart.On (b)(6), 2013, the patient presented to the implanting hospital with symptoms of congestive heart failure and ascites.A cardiac ct revealed the right atrial disc of the aco was partially occluding the ivc flow.The patient was transferred to a surgical hospital where the aco was surgically removed and the asds were surgically repaired.Review of the transesophageal echo showed that the left atrial disc apposed to the septum well but the right atrial disc appeared to be caught by the eustachian ridge.Fluoro imaging confirmed that there was a large separation between the two discs of the aco.
