About this episode

This episode discusses the outcomes of left atrial appendage closure versus oral anticoagulation in patients with atrial fibrillation based on a sub-analysis of the CHAMPION-AF trial.

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. Join Digital Education Committee member Sandeep A. Saha, MD, MS, FHRS and his colleagues Scott C. Brancato, MD, FHRS and Rakesh Gopinathannair, MBA, MD, FHRS for this late-breaking coverage from Heart Rhythm 2026 in Chicago! Learning Objectives Review the rationale for left atrial appendage closure as an alternative to long-term oral anticoagulation in patients with atrial fibrillation following catheter ablation. Analyze the CHAMPION-AF sub-analysis outcomes comparing LAAC and NOAC therapy with…
