Key result
Wiring and ballooning technique successfully retrieves an acutely dislodged WaveCrest LAA occluder.
Why the study?
Device embolization is a notable complication of percutaneous LAA closure requiring retrieval, but transcatheter retrieval options for an acutely dislodged WaveCrest occluder had not been reported.
Case Report (n=1)
A 'wiring and ballooning technique' is a viable transcatheter option for retrieving a dislodged WaveCrest LAA occluder, which lacks hooks or feet suitable for grasping.

May offer retrieval option for dislodged WaveCrest occluders; hypothesis-generating and should not yet change practice.
Percutaneous left atrial appendage (LAA) closure is an alternative therapy in patients with atrial fibrillation who are not suitable for anticoagulation. However, device embolization is one of the notable complications which inevitably requires catheter or surgical retrieval. In addition to previously reported Watchman® or AMULET® occluder embolization, here we report the first case of a WaveCrest® occluder dislodgement which was successfully removed by transcatheter technique. Instead of using the well-known snaring technique, we used a "wiring and ballooning technique" for retrieval. Considering its specific architecture without having hooks or feet where suitable for grasping, this technique is an option for retrieving WaveCrest® devices.

Okamoto et al. (2019) conducted a case report in Atrial fibrillation with dislodged WaveCrest left atrial appendage occluder (n=1). Wiring and ballooning technique for transcatheter retrieval was evaluated on Successful device retrieval. A wiring and ballooning technique successfully retrieved an acutely dislodged WaveCrest left atrial appendage occluder.
