Area of Science:

Interventional Cardiology
Medical Device Technology

Background:

Transcatheter left atrial appendage occlusion (LAAO) is a minimally invasive procedure.
Device malposition is a rare but significant complication.

Purpose of the Study:

To report a novel technique for retrieving a malpositioned LAAO device.
To demonstrate successful LAAO after device retrieval.

Main Methods:

A Watchman FLX device shifted after implantation.
An AngioVac catheter and Raptor forceps were used to grasp and extract the Watchman FLX.
A second LAAO procedure was performed with an Amulet device.

Main Results:

The malpositioned Watchman FLX device was successfully retrieved intact using the AngioVac system.
Successful LAAO was achieved with a replacement Amulet device.

Conclusions:

The AngioVac catheter provides a viable option for LAAO device retrieval.
Proceduralists must be prepared to manage high-risk complications like device malposition.
