This New England Journal of Medicine study from the CHAMPION-AF trial compared left atrial appendage closure (LAAC) using the WATCHMAN FLX device with non–vitamin K oral anticoagulants (NOACs) in 3,000 patients with nonvalvular atrial fibrillation eligible for anticoagulation therapy. The trial found that LAAC was noninferior to NOACs for preventing stroke, cardiovascular death, and systemic embolism, while significantly reducing non-procedural bleeding over three years of follow-up. These findings suggest LAAC may emerge as a viable first-line alternative to long-term anticoagulation in…
