ICE-guided CTI ablation with PFA: Cavotricuspid isthmus ablation with a circular-shaped pulsed field ablation catheter guided by intracardiac echocardiography
Study summary
This observational study aims to evaluate the effectiveness and safety of a circular-shaped pulsed field ablation (PFA) catheter for CTI ablation under the guidance of intracardiac echocardiography (ICE). The main question it aims to answer is:
Is the circular-shaped PFA catheter an effective and safe tool for achieving acute success for CTI ablation? Patients undergoing CTI ablation with a circular-shaped PFA catheter will be prospectively enrolled.
