Catheter Ablation for Paroxysmal Atrial Fibrillation — Have We Reached the Tipping Point?

This editorial discusses evidence from the EARLY-AF trial and its follow-up, comparing first-line cryoballoon ablation versus antiarrhythmic drugs in patients with symptomatic paroxysmal atrial fibrillation. Over 3 years, ablation reduced atrial fibrillation recurrence by ~50% and progression to persistent AF by 75%, improved quality of life, and lowered hospitalization rates. Although trial patients were relatively low-risk and had continuous implantable monitoring, results underscore the potential benefit of early rhythm control with ablation. The authors highlight limitations including generalizability to higher-risk populations and long-term morbidity/mortality effects, suggesting more randomized data are needed before expanding first-line ablation recommendations further.
