Right‐Sided Free Wall Accessory Pathway Refractory to Conventional Catheter Ablation: Lessons From 3‐Dimensional Electroanatomic Mapping

Abstract

RFW APs resistant to conventional catheter ablation might be due to unique anatomic AP features such as more epicardial course at the annulus level with atrial insertion distant from the tricuspid annulus. Electroanatomic mapping is helpful to accurately localize the atrial insertion sites of these APs and facilitates catheter ablation.
