Introduction：LAmbre occluder (Lifetech Scientific, Shenzhen, China), a new device for left atrial appendage (LAA) occlusion, is increasingly used, but the procedure for retrieval after dislodgement has rarely reported in human. Methods and Results：An 80-year-old male patient with permanent atrial fibrillation underwent the implantation of LAA occlusion device. The occluder dislodged to left atrium (LA) at the end of procedure. We failed to retrieve device in LA with a LASSO catheter and forceps with the 8.5F sheath. After it suddenly flowing into aortic arch, we successfully retrieved with a 14F flexible sheath and forceps. We also discussed reasons for the device dislodgment and reported experiences for device retrieval. Conclusion: Combination of the 14F flexible sheath and forceps could be used to retrieve the dislocation of LAA occlusion device.
