Figure 3 Kaplan-Meier curves compare the occurrence of atrial fibrillation/atrial flutter/atrial tachycardia after the initial ablation procedure between the 2C1L group (red line) and the 2C group (blue line). Ablation strategy involving pulmonary vein isolation (PVI) alone is labeled “2C”, while PVI combined with mitral isthmus ablation is labeled “2C1L”.
