Summary: This study analyzed the changes in persistent atrial fibrillation (AF) induced by pulmonary vein isolation (PVI) and left atrium posterior wall isolation (LAPWI) using non-contact charge density (CD) mapping. The results showed that PVI + LAPWI led to changes in AF activation patterns, with a significant decrease in rotational activity in the roof and posterior regions.

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: Localized pulmonary vein scar only facilitates the inducibility of atrial fibrillation in combination with increased left atrial pressure. This is associated with changes in tissue excitability remote from the pulmonary vein scar.

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: Atrial fibrillation (AF) often requires invasive treatment in the form of ablation, but incomplete ablation of the pulmonary veins (PV) can still cure AF in some patients. This suggests that an antiarrhythmic effect other than electrical isolation plays a role in preventing AF. We propose that modifying the arrhythmogenic substrate in the PV can be a new therapeutic approach for a subgroup of patients with PV reentry.

Summary: This study retrospectively analyzed the clinical characteristics, treatment strategies, and long-term outcomes of 7 patients with PV stenosis after AF ablation. The results showed that stenting had better long-term PV patency compared to balloon angioplasty alone, suggesting that it should be considered as the first-line approach.

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: 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 utilized noncontact mapping to analyze global conduction patterns in paroxysmal and persistent atrial fibrillation (AF) and their modification during pulmonary vein (PV) ablation. The results showed different conduction patterns between persistent and paroxysmal AF, with PVs remaining a critical region. PV isolation was effective in eliminating PV-related functional phenotypes and affecting the recurrence of other patterns.

Summary: This article describes the catheter ablation procedure for an atrial tachycardia in a 77-year-old male patient after pulmonary vein isolation for atrial fibrillation. High-resolution mapping revealed a figure-of-eight reentrant atrial tachycardia with clockwise rotation in the right pulmonary vein carina and counterclockwise rotation via two conduction gaps along the previous isolation line.

Summary: This study aimed to investigate whether more extensive radiofrequency catheter ablation of the bi-atrial arrhythmogenic substrate instead of clinical arrhythmia ablation alone results in superior clinical outcomes in patients with pulmonary arterial hypertension (PH) and supraventricular arrhythmias. The results showed similar arrhythmia recurrence rates between the two treatment groups, and no excess of procedural complications or clinical events in the extensive ablation group.

Summary: This study aimed to investigate the characteristics of fractionated potentials (FPs) in non-macroreentrant atrial tachycardia (nAT) and introduce a new method of cross-mapping for clarifying their roles. The ratio of FP duration to AT cycle length was different among nAT groups, with a simple cross-mapping method employed to determine FPs responsible for particular patterns. Results showed that FPs could be found on target in most nAT cases following previous AF ablation, with potential implications for differentiation and ablation strategies.

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: This study compared the clinical outcomes between Japanese patients who underwent atrial fibrillation (AF) ablation and those who did not, finding that the ablation group had a lower death rate. However, there were no significant differences between the two groups in terms of stroke/TIA, major bleeding, and cardiovascular events.
