About this study

Official title: Image Fusion of Integrating Fluoroscopy Into 3D Computed Tomography in Guidance of Vein of Marshall Ethanol Infusion During Persistent Atrial Fibrillation Ablation

The study is a prospective, randomized, single-blind clinical trial aiming to compare two method in guidance of Vein of Marshall ethanol infusion (VOMEI), i.e., the conventional fluoroscopy-guided VOMEI and UNIVU-guided VOMEI.

Read the detailed description

A total of 100 participants with persistent or longstanding persistent AF who undergo radiofrequency catheter ablation will be randomized assigned to two groups at 1:1 ratio to receive Vein of Marshall ethanol infusion (VOMEI).

Group 1: VOMEI guided by fluroscopy alone Group 2: VOMEI guided by fluoroscopy and CARTO UNIVU The intraprocedural major endpoints are the change in low-voltage area led by VOMEI (efficacy endpoint) and procedural complications (safety endpoint). The longterm major endpoint is the recurrence of atrial tachyarrhythmia between 3 and 12 months.

What is being measured

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

  1. Changes of low-voltage or scar area before and after VOMEI

    Left atrial voltage mapping will be performed before and after VOMEI. The low-voltage area or scar area will be mesured and compared before and after VOMEI

    Measured: During the procedure

  2. Procedural complications

    Including cardiac tamponade, stroke, systemic embolism, major bleeding, acute coronary syndrome, acute heart failure, and death.

    Measured: within 72 hours

  3. Recurrence of atrial tachyarrhythmias

    Including recurrence of atrial fibrillation, atrial flutter, and atrial tachycardia

    Measured: 3 to 12 months

Secondary outcomes (10)
  1. Rates of mitral isthmus block

    bidirectional block of mitral isthmus

    Measured: During the procedure

  2. New low-voltage or scar area outside mitral isthmus and left pulmonary ridge

    New low-voltage or scar area after VOMEI outside the targeted regions

    Measured: During the procedure

  3. Rates of VOMEI incomplete

    Any reason leading to incomplete VOMEI

    Measured: During the procedure

  4. X ray exposure time

    Procedure-related temporal parameters

    Measured: During the procedure

  5. procedure time

    Procedure-related temporal parameters

    Measured: During the procedure

  6. radiofrequency ablation time

    Procedure-related temporal parameters

    Measured: During the procedure

  7. Rates of intraprocedural termination of atrial fibrillation (not achieved by cardioversion)

    Termination of atrial fibrillation without cardioversion

    Measured: During the procedure

  8. Burden of atrial tachyarrhythmia

    Evaluation by Holder monitoring at 12 months

    Measured: 12 months

  9. Recurrence of atrial flutter

    recurrence of atrial flutter > 30 second by ECG or Holder monitoring

    Measured: 3 to 12 months

  10. Volume of ethanol and contrast agent used

    ethanol volume, contrast agent volume used during the procedure

    Measured: During the procedure

Questions about this trial

What is this clinical trial studying?

A study testing Vein of Marshall ethanol infusion in people with Persistent Atrial Fibrillation and Longstanding Persistent Atrial Fibrillation, run by Xinhua Hospital, Shanghai Jiao Tong University School of Medicine 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 4 inclusion and 19 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: status not confirmed, as of the sponsor's last update on 15 Dec 2022. 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?

Results are not available in the source record.

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

Contact Mu Chen, MD (021-25077287, chenmu@xinhuamed.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes of low-voltage or scar area before and after VOMEI (time frame: During the procedure). The study lists 3 primary outcomes in all. 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 Dec 2022; AzTrials last refreshed its copy on 8 Nov 2026.
