Brief summary (registry, in English)
This study is a prospective, single-center, single-arm clinical trial planning to screen and enroll 200 subjects. It aims to evaluate the efficacy and safety of pulsed field ablation (PFA) using the FARAPULSE™ system for pulmonary vein isolation (PVI) and superior vena cava isolation (SVCI) in Chinese patients with paroxysmal atrial fibrillation (PAF). Baseline preoperative data, along with intraoperative and postoperative follow-up information, will be collected. The primary endpoint is the proportion of subjects achieving successful PVI and SVCI using solely the FARAPULSE™ PFA system. Secondary endpoints include long-term procedural success rates and various procedural parameters. Additionally, the incidence of adverse events will be recorded as safety endpoints. The study adopts a single-arm target value design hypothesis, and research data will also be compared with historical data from patients treated with radiofrequency ablation for PVI and SVCI to further evaluate the efficacy of PFA. Subgroup analysis will be conducted in patients with heart failure to assess the efficacy and safety of PFA in this population.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Contraindications to pulsed field ablation (e.g., left atrial appendage thrombus, post-atrial septal defect device closure, permanent metallic implants in the left atrium) or contraindications to anticoagulant therapy.
Other illness
- AF secondary to electrolyte imbalance, thyroid disorders, or other reversible/non-cardiac causes.
- Other conditions deemed inappropriate for inclusion by the investigator.
Other
- Persistent atrial fibrillation.
- Presence of persistent left superior vena cava.
- Unsuitable for deep sedation/anesthesia per operator assessment.
- Life expectancy less than 1 year.
Who the study is looking for
- Age between 18 and 75 years.
- Documented diagnosis of paroxysmal atrial fibrillation (PAF), defined as typical AF electrographic characteristics (absence of P waves with irregular fibrillatory waves) recorded on 12-lead ECG or symptomatic Holter monitoring, with each episode lasting less than 7 days.
- Symptomatic despite attempted antiarrhythmic drug therapy.
- Scheduled to undergo initial catheter ablation procedure.
- Voluntarily provided written informed consent.
