The objective of this study was to evaluate the long-term efficacy of FIRM ablation with PVAI vs PVAI plus posterior wall isolation (PWI) and non-PV trigger ablation in persistent (PeAF) and long-standing persistent AF (LSPAF) patients. The procedure time was recorded to be 180.6 ± 35.9 and 124.03 ± 45.4 minutes in the FIRM+PVI and PVI + PWI + non-PV trigger ablation group respectively. At 24-month follow-up, 24% (95% CI 8.7%–37.8%) in the FIRM-ablation group and 48% (95% CI 27.6–63.3%) in the non-PV trigger ablation group remained arrhythmia-free off-antiarrhythmic drugs after a single procedure. Clinical Trial Registration: ClinicalTrials.gov (Identifier: NCT02533843).
