Efficacy of ablation lesion sets in addition to pulmonary vein isolation (PVI) in paroxysmal atrial fibrillation ablation studies. Multivariable meta‐regression results are reported. Point estimates represent absolute difference in success rate as compared with PVI only. PVI with any additional lesion sets analysis (PVI plus): residual I ²=88%; individual lesion set analysis: residual I ²=87%. CFAE indicates complex fractionated atrial electrogram; SVC, superior vena cava; SVC isolation, all: SVC isolation performed in all patients; SVC isolation, triggered: SVC isolation only in patients with SVC triggers.
