A 60-year old male with paroxysmal atrial fibrillation underwent a combined procedure of left atrial appendage occlusion and pulmonary vein isolation. However, an acute intraprocedural 24-mm Watchman device dislodgement occurred, and thus a decision for urgent surgery was made. However, it was noted during the surgery that the device had migrated further to the descending aorta, just distal to the left subclavian artery. Since a right sternotomy access for retrieval was not feasible, a percutaneous approach was justified. A homemade snare was created using a combination of a long sheath, J-wire, and a regular snare, and the device was successfully retrieved without significant difficulty.

一名患有阵发性房颤的 60 岁男性接受了左心耳封堵和肺静脉隔离的联合手术。然而，手术中发生了急性 24 毫米 Watchman 装置移位，因此决定进行紧急手术。然而，在手术过程中注意到该装置进一步迁移到降主动脉，就在左锁骨下动脉的远端。由于正确的胸骨切开术取回是不可行的，经皮方法是合理的。使用长护套、J 线和普通圈套的组合制作了一个自制圈套，并且该装置在没有太大困难的情况下成功取回。
