Summary: This study evaluated the efficacy of CLOSE-guided pulmonary vein isolation (PVI) in the treatment of persistent atrial fibrillation (AF). The results showed that CLOSE-guided PVI achieved a high single-procedure arrhythmia-free survival rate of 80% at 1 year under intensive cardiac rhythm monitoring. However, larger-scale studies are still needed to further confirm these findings.

Summary: This study investigated the characteristics of patients undergoing redo AF ablation and the impact of different ablation strategies. The results showed that pulmonary vein reconnection was common among all techniques of AF ablation, and different ablation strategies did not improve long-term success.

Summary: This study investigated the extension of lesions on the posterior wall and roof of the left atrium after cryoballoon-based pulmonary vein isolation. The results showed that significant portions of the posterior wall and LA roof remained unablated after the procedure, potentially contributing to AF recurrence.

Summary: This study investigated the association of 2D and 3D left atrial strain with low-voltage area in relation to the recurrence of atrial fibrillation after pulmonary vein isolation. The results showed that 3D left atrial reservoir strain and pump strain were lower in patients with recurrent AF. Furthermore, the association of 3D left atrial strain with recurrence of AF was independent of other clinical and echocardiographic parameters, making it a potential predictor for outcomes in patients undergoing PVI.

Summary: This study evaluated the impact of the spatial relationship between LSPV and LAA on recurrence after catheter ablation for paroxysmal AF. The study found that an abutting LAA-LSPV was associated with a higher chance of AF recurrence.

Summary: This study investigated the occurrence of atrial fibrillation (AF) in octogenarians with dual-chamber permanent pacemakers (PPM) and its association with long-term mortality. The study found that diabetes, urea levels, albumin levels, paced QRS duration, and the frequency of atrial high-rate episodes (AHREs) were independently associated with a long-term risk of AF in these patients. Furthermore, left ventricular ejection fraction, left atrial anteroposterior diameter, and AHRE + AF were identified as independent risk factors for long-term mortality in octogenarians with dual-chamber PPM implants.

Summary: In the Swiss Atrial Fibrillation Cohort study, there was no consistent evidence of an association between pulmonary vein isolation (PVI) and neurocognitive function in atrial fibrillation patients.

Summary: This study aimed to evaluate the impact of age on the efficacy and safety of cryoballoon pulmonary vein isolation (cryoPVI) in elderly patients. The results showed that elderly patients (>=75 years) had an approximately threefold higher risk of symptomatic atrial fibrillation (AF) recurrence after cryoPVI compared to younger patients.

Summary: Adenosine-induced atrial fibrillation (AIAF) does not affect the long-term recurrence rate after pulmonary vein isolation (PVI). Additional ablation for the trigger site of AIAF does not improve clinical outcomes.

Summary: For patients undergoing radiofrequency pulmonary vein isolation, the necessity of pulmonary vein angiography was investigated after the use of high-resolution mapping catheters and high-power, short-duration ablation technique. The study found that omitting pulmonary vein angiography had no significant impact on the efficacy, efficiency, and complications of the ablation procedure. Therefore, avoiding pulmonary vein angiography may be useful, especially for young patients and those with chronic renal disease, when using this protocol.

Summary: The study aimed to personalize the ablation index (AI) based on left atrial wall thickness (LAWT) and investigate its effectiveness in PV antrum isolation for persistent atrial fibrillation (PeAF). The results showed that this personalized approach was effective and efficient, with low procedure, fluoroscopy, and RF time. The importance of this study lies in providing a new method for the treatment of PeAF.

Summary: This study investigated the acute and long-term outcomes of cryoballoon PVI vs PVI+PWI in patients with symptomatic PAF. The results showed that PVI+PWI treatment was associated with greater freedom from recurrent atrial arrhythmias and AF during long-term follow-up, compared to PVI alone.

Summary: The study compared cryoballoon pulmonary vein isolation (PVI) with standard radiofrequency cavotricuspid isthmus (CTI) ablation for the first-line treatment of typical atrial flutter (AFL). The results showed that cryoballoon PVI was equally effective as CTI ablation in preventing the recurrence of atrial arrhythmia and better at preventing new-onset atrial fibrillation (AF).

Summary: This study aimed to evaluate the safety, effectiveness, and acute outcomes of high-power short-duration radiofrequency ablation in patients with persistent atrial fibrillation. The results showed that high-power short-duration radiofrequency ablation had similar success rates and shorter procedural time compared to the control group.
