Trial summary

Previous evidence indicated that the outcomes of both video-assisted thoracoscopic surgical ablation and percutaneous radiofrequency ablation therapy for persistent atrial fibrillation (AF) were unsatisfied. Recently, hybrid ablation therapy for AF had encouraging outcomes. Read more about this study

About this study

Previous evidence indicated that the outcomes of both video-assisted thoracoscopic surgical ablation and percutaneous radiofrequency ablation therapy for persistent atrial fibrillation (AF) were unsatisfied. Recently, hybrid ablation therapy for AF had encouraging outcomes. However, there were no randomized, controlled clinical studies to prove the effectiveness of this new strategy. This study is aimed to compare the outcomes of hybrid ablation with video-assisted thoracoscopic surgical ablation for persistent AF with enlarged left atrium.

What participants receive

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

  • Hybrid ablationProcedure or surgery

    This intervention includes totally thoracoscopic surgical ablation and percutaneous catheter ablation simultaneously.

  • Thoracoscopic surgical ablationProcedure or surgery

    This intervention only includes totally thoracoscopic surgical ablation without percutaneous catheter ablation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Survival rate without any recurrence of AF

    Without detections of AF (episodes longer than 30 seconds)

    Measured: At 12-month after intervention

Secondary outcomes (6)
  1. Burden of AF

    Burden of AF according to Tele-ECG-Card lasting for one week

    Measured: At 12-month after intervention

  2. Quality of life score

    Measured with questionnaire of AF effect on Quality of Life

    Measured: preoperative and 12-month after intervention

  3. Adverse events

    Major adverse cardiovascular events; Major bleeding events; Major thromboembolic events.

    Measured: 12 months follow up

  4. Left atrial function

    left atrial ejection fraction and left atrial expansion index

    Measured: preoperative and postoperative

  5. postoperative complications

    perioperative complication of catheter ablation and thoracoscopic surgical abaltion

    Measured: 30 days after operation

  6. Survival rate without any recurrence of atrial tachyarrhythmia

    Survival rate without AF, atrial flutter or atrial tachycardia will be defined by absence of any of these electrocardiographically documented events lasting > 30 seconds.

    Measured: At 12-month after intervention

Questions about this trial

What is this clinical trial studying?

A study testing Hybrid ablation and Thoracoscopic surgical ablation in people with Persistent Atrial Fibrillation, run by China National Center for Cardiovascular Diseases at 1 site in China.

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 2 inclusion and 8 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: finished, as of the sponsor's last update on 27 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Survival rate without any recurrence of AF (time frame: At 12-month after intervention). 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 27 Apr 2023.
