Intracardiac Echocardiography-Guided Cavotricuspid Isthmus Ablation With a Circular-Shaped Pulsed Field Ablation Catheter: A Prospective Study on Effectiveness and Safety
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.
Inclusion: Paroxysmal or persistent atrial fibrillation; Aged 18 years or older; Scheduled for CTI ablation; Able and willing to provide written informed consent.
Exclusion: Previous CTI ablation; Significant congenital heart disease or structural anomaly affecting the CTI; Severe renal/hepatic insufficiency; Active systemic infection or sepsis; Active intracardiac thrombus; Pregnancy or lactation; Life expectancy of less than 12 months; Unable to provide written informed consent.
