Left atrial appendage closure (LAAC) devices can be inadvertently released into unfavorable locations, which may allow them to migrate to a different position within the left atrial appendage or embolize from the heart into the aorta. In such instances, it can be challenging to remove the LAAC device. Here, we present two cases in which patients with atrial fibrillation experienced LAAC device exposure at an inappropriate site because of interventional operator error and device mismatch: (a) the LAAC device was dislodged into the aortic arch and retrieved percutaneously from the femoral artery route, and (b) in the left atrium, which was dislodged into the left atrium and retrieved atrial transseptal puncture of the femoral vein.
左心耳封堵（LAAC）装置可能会意外释放到不理想的位置，这可能使其在左心耳内迁移到不同位置或从心脏栓塞至主动脉。在这种情况下，取出LAAC装置可能具有挑战性。在此，我们介绍两例因介入操作者失误和装置不匹配导致房颤患者的LAAC装置在不适当部位暴露的病例：（a）LAAC装置移位至主动脉弓并经皮从股动脉途径取出，以及（b）在左心房内，该装置移位至左心房并经股静脉房间隔穿刺取出。
