Trial summary

Atrial fibrillation (AF) is connected with an increased morbidity and mortality. In addition, quality of life is diminished due to palpitations, dyspnea, dizziness and syncope. AF is frequently associated with valvular and coronary disease. Read more about this study

About this study

Official title: A Prospective Randomised Multicentre Comparison on Health Related Quality of Life: the Value of Add-on Arrhythmia Surgery in Patients With Atrial Fibrillation Undergoing Valvular and/or Coronary Bypass Surgery

Atrial fibrillation (AF) is connected with an increased morbidity and mortality. In addition, quality of life is diminished due to palpitations, dyspnea, dizziness and syncope. AF is frequently associated with valvular and coronary disease. In the AF patients undergoing valvular or coronary surgery the arrhythmia almost always relapses. For symptom control anti-arrhythmic drugs and cardioversion are used but breakthrough arrhythmias and side effects of the drugs happen frequently. For more effective symptom control "add-on" arrhythmia surgery is being advocated. However, at present the investigators do not know whether add-on arrhythmia surgery indeed affects morbidity and quality of life.

The hypothesis being studied is that add-on arrhythmia surgery in patients with AF undergoing valvular or coronary surgery improves quality of life, establishes chronic sinus rhythm and reduces perioperative and long-term morbidity associated with AF.

Read the detailed description

Multicentre prospective parallel randomised controlled trial. In total 150 patients with documented atrial fibrillation (chronic and paroxysmal), were randomly assigned by a central computer system to undergo cardiac surgery with add-on surgery or without. This assignment was blinded to patients and all medical personnel except for the surgical team during total follow up. Patients completed quality of life questionnaires, comprising the RAND 36-item Health Survey 1.0 (SF-36), Multidimensional Fatigue Inventory-20 (MFI-20) and EuroQoL (EQ-5D and VAS) at baseline and 3, 6 and 12 months following operation.

What participants receive

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

  • Pulmonary vein isolation using microwave energyProcedure or surgery

    Also called PV-isolation

    The surgical ablation procedure is the first step during surgery and is performed before institution of cardiopulmonary bypass allowing off-pump beating heart ablation. The off-pump beating heart ablation procedure is performed according to a specific box lesion surrounding the pulmonary veins, using microwave energy. Afterwards cardiac surgery is performed as usual in both treatment arms.

Study groups in NCT00886080
Study groupRoleWhat they receive
Add-on arrhythmia surgeryExperimentalAdjuvant anti-arrhythmic surgery consists of a beating heart epicardial "box" isolation of all pulmonary veins using microwave energy (Flex 4 or Flex 10 ablation probes and Microwave generator by Guidant/Afix, Fremont, CA, USA). The surgical ablation procedure is the first step during surgery and is performed before institution of cardiopulmonary bypass allowing off-pump beating heart ablation. In addition excision or exclusion of the left atrial appendage is performed in both the treated as the control group.
Receives: Procedure: Pulmonary vein isolation using microwave energy

What is being measured

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

  1. Quality of life and maintenance of sinus rhythm at 1 year will be considered as primary end points.

    Measured: Baseline, 3, 6, and 12 months after operation

Secondary outcomes (1)
  1. In-hospital and out-of-hospital morbidity and mortality during one year follow-up

    Measured: Baseline, 1, 6 and 12 months after operation

Questions about this trial

What is this clinical trial studying?

A study testing Pulmonary vein isolation using microwave energy in people with Atrial Fibrillation, run by Maastricht University Medical Center at 1 site in Netherlands.

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 3 inclusion and 4 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 22 Apr 2009. 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 Netherlands. 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?

Quality of life and maintenance of sinus rhythm at 1 year will be considered as primary end points. (time frame: Baseline, 3, 6, and 12 months after operation). 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 NCT00886080, which also lists 1 linked publication.

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 22 Apr 2009.
