The Lead Episode 152: A Discussion of Outcomes of Left Atrial Appendage Closure versus Oral Anticoagulation in Patients with Atrial Fibrillation and Prior Ablation: A Sub-Analysis of the CHAMPION-AF Clinical Trial (New England Journal of Medicine)

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 appropriately selected AF patients. Digital Education Committee Member Danesh Kella, MBBS, FHRS discusses this article from the Heart Rhythm Journal that preceded the Heart Rhythm 2026 Late-Breaking Clinical Trial. He is joined in the conversation by Jason T. Jacobson, MD, FHRS, Ammar M. Killu, MBBS, and Gregory M. Marcus, MD, FHRS. Learning Objectives Describe the rationale for left atrial appendage closure as an alternative to chronic oral anticoagulation in patients with atrial fibrillation after catheter ablation. Review the efficacy and safety outcomes from the CHAMPION-AF sub-analysis comparing LAAC and NOAC therapy in post-ablation AF patients. Discuss patient selection considerations and the role of shared decision-making when choosing stroke prevention strategies following AF ablation.
