Clinical Characteristics and Timing of Accessory Pathway Reconduction During Catheter Ablation of Accessory Pathways

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
Intra‐procedural accessory pathway reconduction occurred in 18% of patients, with 65.2% of events detected ≥ 15 min after initial pathway elimination. Reconduction was associated with a higher rate of late recurrence, supporting careful assessment for conduction recovery during the post‐ablation waiting period.

Ablation at the Coronary Sinus Diverticular Neck for a Posteroseptal Accessory Pathway With Coronary Sinus Ostial Atresia

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
After failed annular ablation for a posteroseptal accessory pathway with coronary sinus ostial atresia, direct coronary sinus angiography delineated a coronary sinus diverticulum with left atrial drainage. Targeted mapping localized the effective ablation site to the diverticular neck, where radiofrequency delivery eliminated accessory pathway ...

Hemoglobin Levels as a Marker of Arrhythmia Recurrence After Atrial Fibrillation Ablation

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
Lower hemoglobin levels are associated with increased arrhythmia recurrence after radiofrequency ablation but not cryoballoon ablation. The stronger association in patients with non‐paroxysmal AF suggests that low hemoglobin may reflect an adverse atrial substrate rather than a procedural effect.

Multimodality Imaging‐Guided Pulsed Field Ablation for Atrial Fibrillation in Cor Triatriatum Sinister

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
Multimodality imaging facilitated safe transseptal access and catheter navigation in a patient with cor triatriatum sinister. CARTO‐integrated VARIPULSE pulsed‐field ablation achieved pulmonary vein isolation without complications, demonstrating a feasible treatment strategy for atrial fibrillation in complex congenital left atrial anatomy.

Efficacy and Safety of 60 W Versus 90 W, 4‐s Radiofrequency Applications to the Esophagus‐Adjacent Left Atrial Posterior Wall During Pulmonary Vein Isolation: A Pilot Study

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
In this randomized pilot study, 60 W and 90 W QMODE+ RF applications for the periesophageal region achieved comparable acute block and low esophageal injury rates (4.2% each), with similar 1‐year arrhythmia‐free survival, although contact force was higher in the 60 W group.
