Successful Left Atrial Appendage Closure with Watchman Device Implantation in Two Patients with Inferior Vena Cava Filters

Abstract

Percutaneous procedures through femoral access in patients with inferior vena cava (IVC) filter may be at risk of complications. We evaluated the feasibility and safety of left atrial appendage closure (LAAC) through femoral access in patients previously implanted with IVC filter. We described the WatchmanTM device implantation in two patients with formal contraindication for oral anticoagulation. First patient had a GreenfieldTM filter and the second one an OpteaseTM filter, and in this patient an attempt to withdrawal the filter immediately before the LAAC procedure failed. A femoral approach was performed in both patients using a 14 Fr sheath. Before crossing IVC filters, venographies did not detect any thrombus. All steps of IVC filter crossing were performed under fluoroscopic guidance. No immediate or intrahospital complications related to the procedure occurred. Herein, we presented two cases of successful LAAC closure with Watchman device in patients with two different kinds of IVC filters.
