(A and B) Kaplan–Meier curves depicting time to first atrial fibrillation (AF) recurrence (A) and time to first AF, atrial flutter (AFL), or atrial tachycardia (AT) recurrence (B) after one procedure

in the pulmonary vein isolation (PVI) strategy, the complex fractionated electrogram (CFE) strategy, and the combined strategy of PVI followed by CFE ablation (PVI + CFE).
