Background:
The left atrial appendage occlusion (LAAO) device is a noninferior alternative to anticoagulation therapy in patients with atrial fibrillation. Device embolization is a rare but possible complication, often requiring surgical intervention specifically for left ventricular retrieval.
Case Summary:
An 80-year-old woman underwent LAAO device placement according to standard protocol, but the device embolized within a few hours. The embolized LAAO device was successfully retrieved percutaneously with a triple-loop snare using a combined transseptal and transarterial approach.
Discussion:
The percutaneous approach highlighted in the case offers a unique, minimally invasive method for retrieving the embolized LAAO device, thereby avoiding the need for open heart surgery.
Conclusions:
LAAO device embolization is a rare potential complication that requires monitoring after the procedure. Percutaneous retrieval using a triple-loop snare is a viable option.
