About this study

Official title: Surgical Ablation Versus No Surgical Ablation for Patients With Persistent or Longstanding Persistent Atrial Fibrillation (AF) Undergoing Mitral Valve Surgery

The purpose of the research is to determine whether treating atrial fibrillation with surgical ablation during scheduled mitral valve surgery is better than mitral valve surgery by itself without the surgical ablation. Surgical ablation of atrial fibrillation is a technique used by surgeons to deaden atrial heart tissue and block electrical signals that may be causing your heart to beat irregularly. There are no new procedures being tested in this study; both mitral valve surgery and surgical ablation are used regularly in patients who have mitral valve problems and atrial fibrillation, although no surgical ablation devices have been approved by the Food and Drug Administration for the treatment of atrial fibrillation. What is not known with certainty, is whether patients with atrial fibrillation who are having planned mitral valve surgery would do better if they also had surgical ablation rather than medication alone to treat their atrial fibrillation.

Read the detailed description

The purpose of this study is to determine whether the addition of surgical ablation to planned mitral valve surgery for patients with persistent or longstanding persistent AF (within 6 months prior to randomization) reduces the incidence of postoperative heart arrhythmia compared to mitral valve repair with medication therapy alone. This is a randomized, multi-center trial which will enroll 260 subjects who will be randomized in a 1:1 fashion to: (a) mitral valve surgery plus surgical ablation or (b) mitral valve surgery without ablation (control group). All patients will undergo ligation or excision of the left atrial appendage. Patients assigned to the ablation group will be further randomized (1:1) to one of two lesion sets: (1) pulmonary vein isolation only or (2) biatrial Maze lesions. The target population for this trial consists of adult patients with mitral valve disease requiring surgical intervention and persistent or longstanding persistent atrial fibrillation. All patients who meet the eligibility criteria may be included in the study regardless of gender, race or ethnicity. The primary efficacy endpoint is freedom from AF, which will be measured by 3-day continuous monitoring at 6 months and 12 months post-ablation. The primary safety endpoint is a composite of death, stroke, serious cardiac events (heart failure, myocardial infarction), cardiac re-hospitalizations, transient ischemic attack, pulmonary embolism, peripheral embolism, excessive bleeding, deep sternal wound infection/mediastinitis, damage to specialized conduction system requiring permanent pacemaker, damage to peripheral structures, such as the esophagus, within 30 days post-procedure or hospital discharge (whichever is later).

What participants receive

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

  • MVSProcedure or surgery

    Also called Mitral Valve Repair, Mitral Valve Replacement

    All participants will have their left atrial appendage excised or excluded. For mitral regurgitation, the procedures will be a valve repair in the majority of cases. For valves that are not amenable to repair, and for most cases of mitral stenosis, a valve replacement will be performed.

  • AblationDevice

    Also called Surgical Ablation

    For participants treated by pulmonary vein isolation, two separate encircling lesions will be made around the left and right pulmonary veins. For participants treated with biatrial maze lesion set, the left atrial lesions will include, the two encircling lesions, as well as connecting lesions between to the pulmonary veins, from the pulmonary veins to the mitral valve annulus, and from the pulmonary veins to the left atrial appendage. The right pulmonary veins will be isolated first. Isolation will be confirmed by pacing the pulmonary veins at the previously identified threshold for capture. If no atrial capture is noted, it will be inferred that the right pulmonary veins were isolated. If atrial capture is noted, additional ablations on the atrial cuff will be performed until isolation is confirmed. This will be repeated on the left pulmonary veins.

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 14 inclusion and 1 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 6 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 21 sites in United States, Canada. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Nov 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Freedom From Atrial Fibrillation (time frame: Measured at Month 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00903370, which also lists 2 linked publications.

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 6 Feb 2017; AzTrials last refreshed its copy on 7 Nov 2026.
