CHAMPION-AF reads out in Munich: Outcomes In Patients With Atrial Fibrillation Randomized To Receive Left Atrial Appendage Closure Or Oral Anticoagulation. What result would change your practice — and what's your prediction?
Key result
PFA linked to ~58% fewer acute complications and reduced readmissions for repeat procedures vs cryoballoon.
Why the trial?
Does pulsed field ablation reduce acute complications and readmission for repeat procedures compared to cryoballoon ablation in patients undergoing first-time pulmonary vein isolation?
Population
1,961 patients undergoing first-time pulmonary vein isolation for atrial fibrillation at a German…
Comparison
Pulsed field ablation using the penta-spline… vs Cryo-balloon (CB) ablation (n=1,369)
Design
Cohort
Authors
PFA-associated lower redo rates should not yet change practice; leaves open need for RCTs to confirm durability.
Does pulsed field ablation reduce acute complications and readmission for repeat procedures compared to cryoballoon ablation in patients undergoing first-time pulmonary vein isolation?
Absolute Event Rate: 3.7% vs 8.9%
p-value: p=<0.001
In a large real-world cohort, pulsed field ablation for first-time pulmonary vein isolation was associated with fewer minor complications and a reduced need for repeat procedures compared to cryoballoon ablation.
Wahedi et al. (2026) conducted a cohort in Atrial fibrillation (n=1,961). Pulsed field ablation vs. Cryoballoon ablation was evaluated on Acute overall complications (p=<0.001). Pulsed field ablation was associated with fewer acute overall complications (3.7% vs. 8.9%, P<0.001) and reduced readmissions for repeat procedures (5.9% vs. 12.3%, P<0.001) compared to cryoballoon.
