“…Interestingly, Aryana et al included ablation‐naive patients undergoing PVI+ LAPWI as an index procedure for persistent AF, while the current study focused on patients undergoing LAPWI as a repeat procedure for persAF recurrence after an initial PVI with the CB. In index procedure, also our group has already reported the feasibility and safety of CB‐A for the LAPWI during persistent AF ablation, with similar results and, again, superior to linear RFCA lesion 10 …”

“…Whenever PV reconnection was identified, repeat PVI was performed using CB‐A as previously described. Our approach to LAPWI with CB‐A was described in detail elsewhere 9,10 . Briefly, after PVI, in order to achieve LAPWI, the Achieve®catheter was placed deeply in the LSPV to stabilize the CB‐A that was positioned with the distal freezing surface oriented towards the LAPW.…”

“…Our standard preprocedural management and ablation have been previously described in detail. 9 , 10 After a single transseptal puncture LA access was gained, through a steerable 15 Fr sheath (FlexCath Advance ® , Medtronic©) and an inner lumen mapping catheter (MC; Achieve ® , Medtronic©) was advanced and positioned in each PV ostium. A 28 mm CB‐A (Arctic Front Advance™, Medtronic©) was advanced inflated and positioned at PV ostium.…”

Aims To evaluate the clinical outcome in patients undergoing repeat procedures for recurrent persistent atrial fibrillation following an index cryoballoon (CB‐A) pulmonary vein isolation ablation on a mid‐term follow‐up of 12 months. Methods In this propensity score‐matched comparison, 50 patients undergoing left atrial posterior wall isolation (LAPWI) with the CB‐A were matched to 50 patients treated with additional linear ablation using radiofrequency catheter ablation (RFCA). Results Meantime to repeat the procedure was 9.74 ± 4.36 months. At 12 months follow‐up freedom from atrial tachyarrhythmias (ATas) was achieved in 82% of patients in the LAPWI group and in 62% of patients in the linear ablation group (P = .03). Regression analysis demonstrated that relapses during the blanking period and LA dimensions were independent predictors of ATas recurrences following the repeat procedure. Conclusion LAPWI using CB‐A is associated with a significantly higher freedom from atrial arrhythmias when compared with the RFCA mediated left atrial linear lesions on a mid‐term follow‐up of 12 months in patients with persAF undergoing a redo procedure.
