Abstract Purpose Limited comparative data are available regarding catheter ablation (CA) of atrial fibrillation (AF) using second-generation cryoballoon (CB-2) vs. radiofrequency (RF) ablation in elderly patients (> 75 years old). The present study aimed to compare the costs and clinical outcomes in elderly patients using these two strategies. Methods Elderly patients with symptomatic drug-refractory paroxysmal/short-lasting persistent AF were included in the study. Pulmonary vein isolation (PVI) was performed in all patients. Results A total of 324 elderly patients were included (RF,176; CB-2,148) from September 2016 to April 2019. The CB-2 was associated with shorter procedure time and left atrial dwell time (112.9 ± 11.1 vs. 135.1 ± 9.9 min, P < 0.001; 53.7 ± 8.9 vs. 65.1.9 ± 9.0 min, P < 0.001) but marked fluoroscopy utilization (22.1 ± 3.3 vs. 18.5 ± 3.6 min, P < 0.001). Complications occurred in 3.3% (CB-2) and 6.2% (RF) of patients with no significant different (p = 0.307). The length of stay after ablation was shorter, but the costs were higher in the CB-2 group (1.94 vs. 2.53 days, P < 0.001 and 91,132.6 ± 3723.5 vs. 81,149.4 ± 6824.1 CNY, P < 0.001) compared to the RF group. Additionally, the rate of early recurrence of atrial arrhythmia (ERAA) was lower in the CB-2 group (14.2 vs. 23.3%, P = 0.047), but the long-term success rate was similar between two groups. Conclusions CB-2 is associated with shorter procedure time, left atrial dwell time, and length of stay after ablation, as well as lower ERAA, but its costs and fluoroscopy time are greater than the RF group. Moreover, the rate of complications and long-term success is similar between the two groups.

Backgroup: Limited comparative data exist regarding catheter ablation (CA) of atrial fibrillation (AF) using second-generation cryoballoon (CB-2) ablation versus radiofrequency (RF) ablation in elderly patients (>75 years ). This study aims to compare the costs and periprocedural outcomes in elderly patients using these two strategies. Methods: Elderly patients (>75years) with symptomatic drug-refractory AF were included in the study. Pulmonary vein isolation (PVI) was performed in all patients by CB or RF. The costs and periprocedural outcomes of the two strategies are compared using SPSS 22. Results: 324 elderly patients with symptomatic drug-refractory paroxysmal/short-lasting persistent AF received PVI using RF (n=176) and CB-2 (n=148) from September 2016 to April 2019. The CB-2 was associated with shorter procedure duration and left atrial dwell time (128.9±18.3 vs. 152.8±18.9 minutes, P<0.001; 89.4±18.4 vs. 101.9± 22.2minutes, P <0.001), but greater fluoroscopy utilization (24.3±10.9 vs. 19.2±7.5 minutes, P <0.001). Periprocedural complications occurred in 3.4% (CB-2) and 9.1% (RF) of patients (P=0.037). There was no significant difference between 2 groups for AF/atrial tachycardia (AT) recurrence until discharge (16.2 vs. 18.7%, P = 0.552). The length of stay after ablation was shorter, but the costs were greater in the CB-2 group ( P <0.001). Conclusions: Both CB-2 and RF ablation appear to be safe and effective for AF in elderly patients (>75 years). In addition, CB-2 is associated with shorter procedure time, left atrial dwell time, and length of stay after ablation, as well as lower complication rates, but its costs and fluoroscopy time are greater than those of the RF group.

Second-generation cryoballoon (CB2) - based pulmonary vein isolation (PVI) has demonstrated encouraging clinical results in the treatment of paroxysmal (PAF) and persistent atrial fibrillation (PersAF). Nevertheless, the acute efficacy, safety, and long-term clinical results of CB2-based PVI in patients with a left common pulmonary vein (LCPV) are still a matter of debate. Commented paper by Heeger ChH, et al. analyzes this issue with some practical conclusions.

Abstract Purpose Pulmonary vein isolation (PVI) is the most effective treatment strategy for atrial fibrillation (AF). This study evaluated Pulmonary Vein Isolation Outcome Degree (PVIOD) as a new semi-quantitative measure for PVI success after a 7-year follow-up and determined predictors associated with PVIOD.Methods We enrolled 117 patients with symptomatic AF who underwent PVI and after a 7-year follow-up applied PVIOD with 4 possible outcomes. PVIOD 1 group included patients with successful single PVI. PVIOD 2 group included patients with efficacy after ≥ 2 re-PV isolation and/or additional substrate modification (ASM). PVIOD 3 group contained subjects with clinical success after PVI±ASM. Patients with procedural and clinical failure were in PVIOD 4 group.Results In multivariate ordinal logistic regression analysis PVIOD was independently associated with longstanding persistent AF with paroxysmal AF as referent category: odds ratio (OR) 4.1, 95% confidence interval (95% CI) 1.3-12.8 (P=0.014), left atrial (LA) diameter: OR 1.2, 95% CI 1.1-1.3 (P<0.001) and CHA2DS2-VASc score: OR 1.5, 95% CI 1.0-2.2 (P=0.039). LA size, CHA2DS2-VASc score and AF type predicted 7-year probability for procedural and procedural with clinical failure. LA diameter >41mm (AUC 0.741, 95% CI 0.6-0.8, P<0.001) and CHA2DS2-VASc score ≥2 (AUC 0.718, 95% CI 0.6-0.8, P<0.001) predicted long-term procedural and clinical failure. Conclusion PVIOD is a new classification for PVI success. LA diameter, CHA2DS2-VASc score and AF type are independently associated with PVIOD and predict procedural and procedural with clinical failure after the 7-year follow-up. LA diameter >41mm and CHA2DS2-VASc score ≥2 predict long-term PVI failure.

Abstract Aims Pulmonary vein isolation (PVI) alone in persistent atrial fibrillation (AF) is not as successful as in paroxysmal AF, and recent data indicate the key role of non-PV triggers. We aimed to assess the long-term safety and efficacy of left atrial appendage isolation (LAAi) as an adjunct to PVI using cryoballoon (CB) in persistent AF. Methods and results We compared 144 persistent AF patients (59 ± 10 years, 51% females) who underwent PVI combined with LAAi with a propensity-score matched cohort of 138 persistent AF patients (59 ± 6 years, 52% female) in whom PVI-only was performed. Baseline and follow-up data including electrocardiography (ECG), 24-h Holter ECG’s, and echocardiography were recorded for all patients. Atrial tachyarrhythmia (ATa) recurrence was defined as detection of AF, atrial flutter, or atrial tachycardia (≥30 s) after a 3-month blanking period. At a mean of 30.5 ± 5.6 months follow-up, 85 (61.6%) patients in the PVI-only group and 109 (75.7%) patients in the PVI+LAAi group were free of ATa after the index procedure (P = 0.008). Ischaemic stroke/transient ischaemic attack was detected in 4 (2.9%) patients in PVI-only group and in 5 (3.5%) patients in the PVI+LAAi group (P = 0.784). Cox regression analysis revealed that the PVI-only strategy was found as a significant predictor for recurrence (hazard ratio 3.01, 95% confidence interval 1.81–5.03; P < 0.001). Conclusions Our findings indicated that CB-based LAAi+PVI was associated with a favourable efficacy compared to PVI-only strategy in patients with persistent AF. Although ischaemic event rates were similar between the groups, rigorous adherence to anticoagulation regime is paramount in order to prevent thrombo-embolic complications.
