Technical aspects of a successful transvascular retrieval of an acutely dislodged WaveCrest® left atrial appendage occluder.

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.
