“…However, a meta-analysis showed PVI with limited linear ablation within the left atrium significantly reduced AF recurrence while more extensive linear lesion or biatrial ablation not. [ 17 ] Therefore, accurately localizing non-PV foci and limited additional ablation using different ablation strategies such as combined cryoballoon and radiofrequency ablation method [ 18 ] is necessary. In this study, except 2 empirical lines, we also ablate in other non-PV triggers based on the CARTO mapping results because ablation of these triggers maybe benefits.…”

Catheter ablation has been wildly used to treat atrial fibrillation (AF) and has achieved a better efficacy for paroxysmal AF (PAF) but not for persistent AF (PerAF). Furthermore, a few data on the efficacy and safety of catheter ablation for PerAF were reported. This study aimed to investigate long-term efficacy of radiofrequency catheter ablation (RFCA) for PerAF and explore predictors of late recurrence of atrial fibrillation (LRAF).A total of 92 consecutive patients with PerAF (64 males, aged 56.42 ± 11.24 years) were enrolled in this study and accepted circumferential pulmonary vein isolation (CPVI) alone or CPVI combined additional ablation.Maintenance rate of sinus rhythm (SR) was 40.2% after a single procedure with median follow-up of 15 months and 52.2% after mean 1.3 ± 0.6 procedures with median follow-up of 26 months. Long-term SR maintenance rate was no statistical difference between patients with CPVI alone and with CPVI combined additional ablation (48.6% vs 35.1%, log rank test, P = .152). Patients with AF duration < 24 months had a higher long-term SR maintenance rate than those with AF duration ≥ 24 months (55.6% vs 30.4%, log rank test, P = .022). AF duration (OR = 1.015, 95%CI 1.001–1.030, P = .015), and early recurrence of AF (ERAF) (OR = 10.654, 95%CI 3.853–29.460, P < .001) were predictors of LRAF after a single procedure.In conclusion, long-term maintenance SR rate was 52.2% in patients with PerAF after multiple procedures with a median over 2-year follow-up. Patients with AF duration < 24 months had better outcome. AF duration and ERAF were predictors of LRAF after a single procedure.

“…It is possible that if RF energy applications had been performed at those "silent" areas, the rate of the freedom from AF in Group CB could have been comparable to that of Group RF. In addition, Guler et al demonstrated that CB provided additional substrate modification owing to the balloon and PV mismatch and could provide a lesion formation at the posterior wall of the left atrium, which is the most affected part of left atrium [32] This may have some influence on the results of the present study.…”

Marshall (VOM-EI) has been proposed as a potentially synergistic adjunctive therapeutic strategy for AF [8,9] . The aim of this study is to investigate whether a VOM-EI translates into an improved rhythm control in paroxysmal AF, and whether the technique chosen for the PVI (RF or CB) has any influence when combined with a VOM-EI. Methods Patients PopulationPatients 44 to 82 years of age who had experienced multiple episodes of AF within the previous 6 months were consecutively enrolled in the study. Patients were excluded if their left atrium (LA) was >55 mm in diameter, or if there was evidence of any LA thrombus. Further exclusion criteria included unstable angina, myocardial infarctions within the previous 6 months, percutaneous transluminal coronary angioplasty within the previous 6 months, an ejection fraction of
