Extracting a Malpositioned Occluder Device Using Endovascular Forceps.

ABSTRACT:

Background

Transcatheter left atrial appendage occlusion (LAAO) is a low-risk procedure with a <1.0% risk of malposition.

Case summary

An 80-year-old man with atrial fibrillation intolerant to apixaban underwent implantation of a 24 mm Watchman FLX device (Boston Scientific), which immediately shifted, exposing uncovered metal in the left atrium. Four weeks later, an AngioVac F22¹⁸⁰ catheter (AngioDynamics) was advanced into the left atrium and a 10-mm Raptor grasping forceps (Steris) was introduced via the AngioVac catheter. Using the Raptor, the Watchman FLX was grasped and with cautious, sustained force extracted into the AngioVac (Video 1) and out of the body intact (Figure 1). A 28 mm Amulet device (Abbott) was then implanted.
