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.

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.

Anaesthetic Techniques for Cardiac Ablation—A Scoping Review

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 9, October 2026.
ABSTRACT Background Cardiac arrhythmias, particularly atrial fibrillation, have rising prevalence and represent a growing global health burden. Catheter ablation is a commonly used treatment demanding sedation or anaesthesia for comfort, stability and safety. Anaesthetic techniques vary globally, and the optimal strategy has yet to be determined.

A Novel Drug‐Loaded Porous Parylene Electrode for Targeted Anti‐Inflammatory Therapy and Hearing Preservation in Cochlear Implantation

Advanced Healthcare Materials, Volume 15, Issue 35, 18 September 2026.
A porous parylene‐coated electrode loaded with dexamethasone was developed to reduce inflammation after cochlear implantation. In guinea pigs, the device provided sustained drug release, maintained biocompatibility, improved auditory brainstem response thresholds, and reduced inflammatory cell infiltration and TNF‐α expression.

Permanent form of junctional reciprocating tachycardia and tachycardia-induced cardiomyopathy treated by catheter ablation: a case report

The Turkish Journal of Pediatrics, 2003
The permanent form of junctional reciprocating tachycardia (PJRT) is usually refractory to drug therapy, and these patients are at risk of developing tachycardia-induced cardiomyopathy. The electrocardiogram insribes inverted P waves in leads 2, 3,
