A-CPVA alone is preferable to M-CPVA for first-time symptomatic AF ablation; confirms complete circular lesion sets improve long-term success.
Does aggressive CPVA alone reduce the recurrence of atrial tachyarrhythmias compared to modified CPVA with segmental ostial ablation in patients undergoing first-time ablation for symptomatic AF?
In patients undergoing first-time ablation for symptomatic atrial fibrillation, achieving pulmonary vein isolation by closing gaps along circular lines (A-CPVA) significantly reduces arrhythmia recurrence compared to adding segmental ostial ablation.
