Abstract:
The LAmbre occluder (Lifetech Scientific, Shenzhen, China), a new device for left atrial appendage occlusion (LAAO), is increasingly used, but the retrieval procedure for dislodgements has rarely been reported in humans. We herein reported a case of safe retrieval of dislodged LAmbre occluder. The occluder dislodged to the left atrium (LA) at the end of the LAAO procedure. We failed to retrieve the device in the LA using a LASSO catheter and forceps through an 8.5F sheath. After it suddenly flowed into the aortic arch, we successfully retrieved it using the same forceps through a 14F flexible sheath. We also discuss the reasons for device dislodgment and experiences of device retrieval. We think that forceps can be used to retrieve an embolized LAmbre device in the aorta through a 14F flexible sheath.
