A Study on the Therapeutic Value of Additional Left Atrial Posterior Wall Isolation Guided by Voltage Mapping in Persistent Atrial Fibrillation.
China350 participantsStarted 2026-04-30
Plain-language summary
This prospective, multicenter, randomized controlled study was designed to investigate the feasibility, efficacy and safety of pulsed field ablation (PFA) strategies for persistent atrial fibrillation. For patients with persistent atrial fibrillation and normal left atrial substrate, pulmonary vein isolation combined with superior vena cava isolation will be performed. For those with abnormal left atrial substrate, two strategies will be adopted: pulmonary vein isolation plus superior vena cava isolation, and pulmonary vein isolation combined with superior vena cava isolation and left atrial posterior wall isolation. Long-term follow-up will be conducted to observe the long-term clinical outcomes.

Inclusion criteria
. Older than 18 years.
. Diagnosed as persistent atrial fibrillation (AF); Definition: At least one episode of persistent AF was recorded on dynamic electrocardiogram (ECG) data within 12 months prior to enrollment, or other clinical evidence supporting persistent AF episodes lasting more than 7 days.
. Subjects are able to understand the purpose of the study, voluntarily participate in the study and sign the informed consent, and are willing to complete the follow-up according to the requirements of the program.
Exclusion criteria
. Atrial fibrillation is secondary to thyroid disease or other reversible factors.
. Evidence of left atrial or left atrial appendage thrombus on imaging examination.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
