Ablation of Accessory Pathways with Challenging Anatomy

Jacopo Marazzato et al. Card Electrophysiol Clin. 2020 Dec.

Abstract

Although catheter ablation of accessory pathways is deemed highly safe and effective, peculiar location of these pathways might lead to complex and potentially hazardous procedures requiring ablation in anatomic regions such as para-Hisian area, coronary sinus, and epicardial surface. The electrophysiologist should know these possible scenarios to plan the best strategy for safe and effective ablation of these uncommon accessory pathways.

Keywords: Atrioventricular accessory pathways; Atrioventricular node; Catheter ablation; Coronary sinus diverticulum; Dilated cardiomyopathy; Epicardial ablation; His bundle; Hypertrophic cardiomyopathy.
