Transient Atrioventricular Block With Focal Pulsed Field Ablation
1Department of Cardiac Electrophysiology, Royal Infirmary of Edinburgh, Edinburgh, UK.
Abstract:
Pulsed field ablation (PFA) is being adopted into widespread use worldwide for the treatment of a wide range of arrhythmias, with attractive tissue selectivity and safety profiles. While single-shot PFA remains the mainstay of atrial ablation at present, focal applications of PFA are emerging as a highly effective means of delivering effective ablation. The present case illustrates transient atrioventricular block following PFA, highlighting potential for conduction system damage with PFA and supporting a cautious approach in close proximity to conduction system structures.
