Figure 4 Kaplan-Meier curves comparing the occurrence of atrial fibrillation/atrial flutter/atrial tachycardia after the initial ablation procedure between the 2 groups in presence of low-voltage zones in the left atrium. Ablation strategy involving pulmonary vein isolation (PVI) alone is labeled “2C”, while PVI combined with mitral isthmus ablation is labeled “2C1L”.
