In the Watchman trials, the risk of stroke after receiving a Watchman device is overall similar, or non-inferior in clinical trial terms, when it was compared to warfarin for stroke risk reduction. The Watchman device is used to close off the left atrial appendage. The device description/function or indication may have changed. Strategy Occlusion of the left atrial appendage can be achieved from an outside perspective (the #Lariat device) or an inside (endovascular) blood exposed device (#Watchman first in this endeavor). J Am Coll Cardiol 2013; 61:2551. While effective in preventing many embolic strokes, it also negates endocrine contribution of the LAA.

The good news is that with an extensive procedural checklist in place to ensure the device is stable, this complication hardly ever occurs. See Editorial by Turagam et al Over the last decade, left atrial appendage occlusion (LAAO) has become an attractive alternative to reduce the risk of stroke in patients with nonvalvular atrial fibrillation (AF), especially when long-term oral anticoagulation (OAC), either a vitamin K antagonist (VKA) or a novel agent (NOAC), is not suitable or hazardous. 2015-11-13T11:52:14Z Are at increased risk for stroke and systemic embolism based on CHADS2 or CHA2DS2-VASc scores and are recommended for anticoagulation therapy; Are deemed by their physicians to be suitable for anticoagulation therapy; and. INDICATIONS FOR USE The WATCHMAN™ Device is indicated to reduce the risk of thromboembolism from the LAA in patients with non-valvular atrial fibrillation who: Are at an increased risk for stroke and systemic embolism based on CHADS2 or CHA2DS2-VASc scores and are recommended for anticoagulation therapy, Are deemed to be suitable for short-term (at least 45 days), but not long-term, … The Watchman LAA Closure Device is indicated as a treatment alternative to patients with AF, either indicated or contraindicated to anticoagulation therapy, thus extending the benefits of the therapy to a wider population and especially to those at higher risk than others. For the Watchman device, this includes OACs for 6 weeks, dual antiplatelet therapy for 6 months, and aspirin for life according to the PROTECT AF trial protocol. This would typically require cardiac surgery to retrieve the device. With all medical procedures there are risks associated with the implant procedure and the use of the device.

The EP Wire survey has revealed that the most common indications for LAAO are stroke prevention in patients at high thrombo-embolic risk and absolute contraindications to oral anticoagulation (OAC) therapy or a history of bleeding. However, some patients at high thrombo-embolic risk cannot be treated with oral anticoagulants (OACs) due to major contraindications or intolerance.
