Does left atrial appendage closure reduce stroke rates as well as oral anticoagulants and antiplatelet meds in A-fib patients?
Abstract
Q: Does left atrial appendage closure reduce stroke rates as well as oral anticoagulants and antiplatelet meds in A-fib patients? EVIDENCE-BASED ANSWER: Yes. Left atrial appendage closure (LAAC) with the Watchman device is noninferior to vitamin K antagonists (VKAs) and non-VKA oral anticoagulants (NOACs) for adults with nonvalvular atrial fibrillation (NVAF) and 1 additional stroke risk factor (strength of recommendation [SOR]: A, multiple meta-analyses). LAAC has consistently been shown to be superior to antiplatelet therapy (SOR: A, single meta-analysis). One randomized controlled trial (RCT) demonstrated superiority of LAAC to VKA (SOR: B, single RCT).
