  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: Patients who underwent concomitant surgical ablation for atrial fibrillation between January 2011 and January 2017 at the University Hospital of Basel. The study population consisted of patients with paroxysmal, persistent, and long-standing persistent AF as defined by the 2020 ESC-Guidelines. Surgical ablation was performed concomitant to cardiac surgery addressing valvular or ischemic heart disease.

Who may be able to join

  • concomitant surgical ablation for atrial fibrillation
  • performed between January 2011 and January 2017 at University Hospital Basel

Who cannot join

  • stand-alone procedure
  • surgical ablation for atrial flutter

About this study

This retrospective single-centre study aims to examine the success rate of concomitant surgical ablation in patients with atrial fibrillation (AF) with an up to eight years follow-up period. Moreover, the focus of this study was to identify variables which predict freedom from AF, such as the type of AF, lesion set performed, energy source used and the patient's characteristics.

What participants receive

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

  • Surgical Ablation for Atrial FibrillationProcedure or surgery

    Surgical ablation in combination with other cardiac procedures through a median sternotomy or thoracotomy. Main procedures were valve surgery (i.e. repair, replacement) and/or coronary artery bypass grafting (CABG). Surgical ablation procedures for atrial fibrillation were divided into three different groups according to Heart Rhythm Society (HRS) expert consensus 2017: (1) Pulmonary vein isolation alone; (2) Pulmonary vein isolation combined with left atrial lesion sets; (3) and biatrial procedure.

What is being measured

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

  1. Freedom from AF one year after surgical ablation

    one-year success

    Measured: 12 months

Secondary outcomes (6)
  1. Freedom from atrial fibrillation (AF) and atrial flutter (AFL) after removal from antiarrhythmic drug therapy

    Measured: from surgical ablation until 10th October 2019

  2. Need of additional arrhythmia interventions

    repeat ablation procedures, electrical cardioversion, pacemaker implantation or implantable cardioverter-defibrillator (ICD) implantation

    Measured: from surgical ablation until 10th October 2019

  3. Use of oral anticoagulation

    Measured: from surgical ablation until 10th October 2019

  4. Perioperative morbidity

    Measured: from surgical ablation until 10th October 2019

  5. Mortality

    Measured: from surgical ablation until 10th October 2019

  6. Evolution of left atrial size

    Measured: from surgical ablation until 10th October 2019

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation and Maze Procedure, run by University Hospital, Basel, Switzerland at 1 site in Switzerland.

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 2 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 26 Sep 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 Switzerland. 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?

Freedom from AF one year after surgical ablation (time frame: 12 months). 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 NCT05542017, 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 26 Sep 2022.
