Late migration of an 18 mm LAmbre left atrial appendage closure device to the iliac bifurcation occurred 105 days post-procedure and was successfully retrieved percutaneously using a novel technique.
Demonstrates a novel and successful percutaneous retrieval technique for a late-migrated left atrial appendage closure device using catheter-based endothelial detachment and bidirectional traction.
Absolute Event Rate: 0% vs 0%
Transcatheter left atrial appendage closure (LAAC) serves as a mechanical stroke prevention strategy for patients with non-valvular atrial fibrillation (NVAF) who are unsuitable for long-term oral anticoagulation. Although device dislodgement following LAAC is rare, it carries potentially life-threatening risks. This case report describes a 65-year-old male with permanent atrial fibrillation (CHA2DS2-VASc = 4, HAS-BLED = 3) who underwent LAAC with an 18 mm LAmbre occluder. Despite confirmed proper positioning at 1-month follow-up, device migration to the iliac bifurcation was detected at 105 days post-procedure, potentially associated with interim chest trauma. Percutaneous retrieval was performed via a novel approach: catheter-based endothelial detachment followed by bidirectional traction, avoiding large-bore sheaths. A Watchman FLX device was subsequently implanted successfully.
