The Lead Episode 151: Heart Rhythm 2026 Late-Breaker Coverage: 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
<table> <tbody> <tr aria-describedby="author-review-submit-abstract-setion-0"> <td data-label="Value"><br /> This late-breaking sub-analysis from the CHAMPION-AF trial evaluated outcomes of left atrial appendage closure (LAAC) with the WATCHMAN FLX device versus oral anticoagulation in patients with atrial fibrillation who had previously undergone catheter ablation. Investigators found that LAAC provided similar protection against stroke, cardiovascular death, and systemic embolism compared with non-vitamin K oral anticoagulants (NOACs), while significantly reducing non-procedural bleeding events, regardless of prior ablation status. These findings suggest LAAC may be a viable alternative to long-term anticoagulation in select post-ablation AF patients through a shared decision-making approach.</td> </tr> </tbody> </table> <p><br /> <br /> Join Digital Education Committee member Sandeep A.

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)
<table> <tbody> <tr aria-describedby="author-review-submit-abstract-setion-0"> <td data-label="Value">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.</td> </tr> </tbody> </table> <p><br /> 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.
