Watchman outcomes comparing post-implantation anticoagulation with warfarin versus direct oral anticoagulants.

Purpose: As left atrial appendage occlusion devices (LAAO) implantation rates grow, continued evaluation on best patient practices is important. We report pooled Watchman outcomes at a multicenter Texas healthcare system with an emphasis on clinical outcomes and post-implantation anticoagulation with direct oral anticoagulants (DOACs) versus warfarin.

Methods: Data for 163 patients with atrial fibrillation (AF) undergoing Watchman implantation was collected via retrospective chart review between June 2016 and June 2018.
