What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • STABLE-SRProcedure or surgery

    homogenization of the low voltage zones and elimination of the complex electrograms from the transitional zones during sinus rhythm

  • STABLE-AFProcedure or surgery

    homogenization of the low voltage zones and elimination of the complex electrograms from the transitional zones during Atrial Fibrillation

  • CPVIProcedure or surgery

    ablate around the pulmonary vein orifice

Questions about this trial

What is this clinical trial studying?

A study testing STABLE-SR, STABLE-AF and CPVI in people with Atrial Fibrillation, run by Yantai Yuhuangding Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 15 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Hongxia Chu, doctorate (15965165932, chuhx1972@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The incidence of no atrial arrhythmias greater than 30 seconds (time frame: at least 18 months follow up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jul 2024.
