An event of pericardial effusion and migration was reported.A medical review of imaging received from the field was conducted and revealed that a "trace" quantity of pericardial fluid is observed posteriorly in sequences 3-5.No leaks are observed, and close criteria were met.The 40-degree view shows no change in the "trace" effusion noted at the initiation of the implant.The provided angiographic implant images show a chicken wing laa subsequently closed with a pseudo-sandwich implant.Offset and disc/lobe separation are noted consistent with the close criteria met in the tee images.Information from the field indicated that a pericardial effusion was detected after a follow up echocardiogram showed the amulet disc impinging upon the ts.However, those images are not available for review and no clinically significant pericardial effusion can be identified.A returned device assessment could not be performed as the device remains implanted and was not returned for analysis.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed, and the product met all specifications.Based on the information received, the cause of the reported incident could not be conclusively determined.
