About this study
Official title: European CURE-AF Study - Concomitant Utilization of Radiofrequency Energy for Atrial Fibrillation
A prospective, non-randomized, multi-center clinical trial. The patient population includes patients with permanent or persistent AF requiring valve replacements or repairs, ASD repairs, PFO closure or coronary artery bypass grafts (CABG) procedures. Patients are not allowed to have had previous atrial ablation, AV-nodal ablation, or surgical Maze procedure.
Read the detailed description
The Cardioblate Surgical Ablation System is cleared in Canada and Europe for ablation of cardiac tissue for the treatment of cardiac arrhythmias. In the United States, the Cardioblate bipolar is approved for soft tissue ablation, while the Cardioblate Pen is approved for cardiac tissue ablation. The purpose of the clinical study is to obtain a labeling claim for the US market that the Cardioblate Surgical Ablation System can be used for ablation of cardiac tissue in the treatment of cardiac arrhythmias such as atrial fibrillation among permanent and persistent AF patients.

Cardioblate surgical ablation systemDevice
This investigation is a prospective, non-randomized multicenter clinical trial evaluating the outcome of patients with AF requiring concomitant open heart surgery plus the Cardioblate Surgical Ablation System using the modified Maze III procedure. The trial population includes patients requiring valve replacements or repairs, atrial septal defect (ASD) repairs, patent foramen ovale (PFO) closure or coronary artery bypass grafts (CABG) procedures.
Surgical RF AblationProcedure or surgery
This investigation is a prospective, nonrandomized multicenter clinical trial evaluating the outcome of patients with AF requiring concomitant open heart surgery plus the Cardioblate Surgical Ablation System using the modified Maze III procedure. The trial population includes patients requiring valve replacements or repairs, atrial septal defect (ASD) repairs, patent foramen ovale (PFO) closure or coronary artery bypass grafts (CABG) procedures.

What is being measured
The primary outcome is the main question the study is designed to answer.
Permanent AF Arm
Primary efficacy endpoint- The percent of patients free of AF, off Class I or III antiarrhythmic drugs and not having received additional ablation therapy, as determined by a 24-hour Holter recording at 6 months follow-up.
Measured: 24-hour Holter recording at 6 months follow-up
Persistent AF Arm
The percent of patients free of AF, off Class I or III antiarrhythmic drugs and not having received additional ablation therapy, as determined by a 24-hour Holter recording at 9 months follow-up.
Measured: 24-hour Holter recording at 9 months follow-up.
Secondary outcomes (2)
Permanent AF Arm
Secondary efficacy endpoints - 24-hour Holter recording, b) improvement in left ventricular ejection fraction and c) left atrial transport function as evidenced by the presence of an A wave at 6 months follow-up.
Measured: 24 hours
Persistent AF Arm
Secondary efficacy endpoints - a) The percent of patients free of AF, regardless of Class I or III antiarrhythmic drug use and not having received additional ablation therapy, as determined by a 24-hour Holter recording, b) improvement in left ventricular ejection fraction and c) left atrial transport function as evidenced by the presence of an A wave at 9 months follow-up.
Measured: 24-hour Holter recording at 9 months follow-up.

Questions about this trial
What is this clinical trial studying?
A study testing Cardioblate surgical ablation system and Surgical RF Ablation in people with Atrial Fibrillation, run by Medtronic Cardiovascular at 5 sites in 3 countries.
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 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 27 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Germany, Norway, Poland. 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?
Permanent AF Arm (time frame: 24-hour Holter recording at 6 months follow-up). The study lists 2 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 27 Nov 2020; AzTrials last refreshed its copy on 31 Oct 2026.
