Prospective Study on the Effectiveness and Safety of Bi-polar Pulse-field Tip-catheter Ablation for Atrial Fibrillation in China（POTENTIAL-AF）
Source: ClinicalTrials.gov · Last updated 4 Jun 2026
Brief summary (registry, in English)
POTENTIAL-AF is a prospective, multicentre, observational registry study evaluating the real-world effectiveness and safety of bi-polar pulse-field tip-catheter ablation (PFA) for atrial fibrillation (AF) in China. The study will enrol 30,000 adult patients with symptomatic paroxysmal or persistent AF who have failed at least one antiarrhythmic drug (Class I or III) and are planned to undergo PFA using the Jinjiang LEAD-PFA system with PulsedFA catheter at participating centres across China. All procedural decisions, including energy settings, ablation targets, and peri-procedural management, are made by the treating physician per routine clinical practice. The study prospectively collects baseline clinical characteristics, intraoperative ablation parameters, and follow-up outcomes at 3 months, 6 months, 12 months, and every 6 months thereafter, for up to 10 years. The primary endpoint is all-cause mortality at 10 years. Secondary endpoints (observed over 5 years) include ischaemic stroke, haemorrhagic stroke, transient ischaemic attack (TIA), cardiovascular death, cardiovascular hospitalisation, systemic embolism, thromboembolic death, major bleeding, and clinically relevant non-major bleeding (CRNMB). By capturing large-scale, standardised, long-term data across diverse Chinese centres, POTENTIAL-AF aims to describe real-world procedural practice patterns, identify predictors of clinical outcomes, and provide evidence to support the safe and effective application of the Jinjiang bi-polar tip PFA catheter in Chinese AF patients.

Who the study is looking for
- Age ≥ 18 years
- Symptomatic paroxysmal AF or persistent AF:
- Paroxysmal AF: self-terminating within ≤ 7 days; ≥ 2 symptomatic episodes in the 6 months prior to enrolment; ≥ 1 ECG or Holter-documented AF episode in the 12 months prior to enrolment
- Persistent AF: duration \> 7 days and \< 1 year; ≥ 1 symptomatic episode in the 6 months prior; documented by Holter or 2 ECGs ≥ 7 days apart within 12 months prior
- Failure of AAD therapy: inadequate efficacy and/or intolerance to ≥ 1 Class I or Class III antiarrhythmic drug
