Intracardiac Echocardiography-Guided Cavotricuspid Isthmus Ablation With a Circular-Shaped Pulsed Field Ablation Catheter

Recruiting now

Conditions studied: Atrial Fibrillation (AF), Atrial Flutter

In brief

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.
