“…After informed written consent was obtained, an electrophysiological study was performed in the postabsorptive state under light sedation [5]. Trans-esophageal echocardiography was performed to exclude the possibility of LA thrombus just before ablation in all patients [6].…”

The success rate of catheter ablation of persistent atrial fibrillation (AF) is not satisfactory, for reasons that are unclear. The purpose of this study was to examine the relationship between left atrial reverse remodeling after ablation and recurrence of AF in patients with persistent AF. One hundred and thirty-two patients with persistent AF were enrolled. Extensive encircling pulmonary vein isolation plus ablation of complex fractionated atrial electrograms was performed. Bepridil or amiodarone was prescribed for 3 months after ablation. All patients were studied by serial echocardiography and 24-h ambulatory electrocardiogram at baseline, for the day after ablation, and at 1-, 3-, and 6-month intervals after ablation. Recurrence of AF was observed in 42 patients at 2-year follow-up. The duration of AF (median 12 (IQR 6-37) vs 8 (IQR 5-17) months, p < 0.05), and early recurrence of AF (69 vs 26%, p < 0.05) after ablation were significantly different between the patients with AF recurrence and those without. The left atrial dimensions at 3 months (40 ± 6 vs 44 ± 6 mm, p < 0.001) and 6 months (40 ± 6 vs 44 ± 6 mm, p < 0.001) were significantly smaller than those just after ablation in the patients without AF recurrence. A 5% reduction from baseline in the left atrial dimension at 6 months after ablation was associated with freedom from late AF recurrence (p < 0.05). Left atrial reverse remodeling after ablation of persistent AF was associated with freedom from late recurrence of AF.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…After constructing three-dimensional electroanatomical maps using a non-fluoroscopic navigation system (CARTO, Biosense Webster), circumferential ablation lines were created around the left-and right-sided ipsilateral PVs using a 4.0 mm tip temperature controlled non-irrigated catheter (Navistar, Biosense Webster) at a maximum power of 30 W and a maximum electrode-tissue interface temperature of 55 • C. The EEPVI end point was the creation of a bidirectional conduction block from the left atrium (LA) to PVs. An additional linear lesion connecting the superior aspects of the left and right upper PV isolation lesions was created for patients with nonparoxysmal AF [6]. If AF was still present after LA ablation, transthoracic cardioversion was performed to restore sinus rhythm.…”

“…Pulmonary vein isolation (PVI) is one of the most common strategies for ablation of paroxysmal AF, but the outcome of PVI alone for patients with persistent AF is poor [8][9][10]. Additional approaches, such as linear ablation after PVI have been reported [11][12][13][14][15].…”
