Article Synopsis
  • Catheter ablation for parahisian accessory pathways (PHAP) is challenging due to their close proximity to the heart's normal conduction system, with cryoablation showing a better safety profile but higher recurrence rates than radiofrequency ablation (RFCA).
  • This study involved 30 patients and compared the effectiveness of RFCA and cryoablation, finding similar acute success rates (93% for RFCA vs. 87% for CRYO) and no significant differences in short-term or long-term recurrence rates.
  • The researchers concluded that both RFCA and CRYO have comparable efficacy and safety profiles when performed by experienced electrophysiologists, with no cases of permanent AV block reported in either method.

Background: The subxiphoid pericardial access is technically difficult and has a considerable rate of complications, thus transatrial access may be an alternative.

Objectives: This study sought to assess the feasibility and safety of this strategy regarding periprocedural period and after 1-week follow-up.

Methods: The investigators performed epicardial mapping through transatrial puncture in 20 swine.

Article Synopsis
  • Atrial tachycardia (AT) ablation near the His-Bundle is risky due to potential AV block, leading researchers to explore catheter positioning on the non-coronary cusp (NCC) as a safer alternative for treatment.
  • This study reviewed ten patients with confirmed para-Hisian focal AT, finding that RF delivery at NCC effectively interrupted tachycardia without causing complications or recurrence during a follow-up period of 30 months.
  • The results suggest that using the NCC for catheter-based treatment of para-Hisian AT is both safe and effective, providing a promising strategy for managing this complex type of arrhythmia.

Introduction: Catheter ablation of the parahisian accessory pathways (PHAP) has been established as the definitive therapy for this type of arrhythmia. However, the PHAP proximity to the normal atrioventricular conduction system makes the procedure technically challenging. Here, we have reported a case series of 20 patients with PHAP who underwent aortic access ablation to evaluate the safety and efficacy of this approach in the PHAP ablation.
