Transcatheter cryo-ablation of septal accessory pathways, multicenter observational study in Japan

Therapeutic strategy using radiofrequency ablation for para‐Hisian accessory pathway

“…Recent literature has favored cryoballoon ablation over conventional radiofrequency approaches due to its reduced invasiveness to the myocardium, although the therapeutic efficacy of cryoballoon ablation remains under debate. 2 Notably, atrioventricular block necessitates pacemaker implantation and escalates the risk of severe complications, such as device‐related infections. Most arrhythmias stemming from para‐Hisian accessory pathways, such as atrioventricular reentrant tachycardia, do not bear a significant association with mortality.…”
