About this study
Official title: Prospective Physician-Initiated Observational Study of The Contact Detection System (CDS) in Patients Undergoing Radiofrequency Ablation Using the Niobe™ Remote Magnetic Navigation System (STAR)
This observational study evaluates peri-procedural results of the Niobe™ Remote Magnetic Navigation (RMN) ES system using the contact detection system (CDS) in patients undergoing standard of care radiofrequency ablation of cardiac arrhythmias.
The objective of this observational study is to confirm system performance of the CDS and that it does not alter pacing, electrocardiograms, or mapping during RF ablation procedures.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CDS box connection of the Niobe™ Remote Magnetic Navigation SystemDevice
For all subjects included in the study, the ablation procedure will be started per standard of care. First mapping, pacing and electrocardiograms of the right atrium will be evaluated without the CDS box connected. Second the CDS box will be connected to the catheter and mapping, pacing and electrocardiograms will be recorded again. Next, ablation will be conducted per standard of care.
| Study group | Role | What they receive |
|---|---|---|
| Patients with cardiac arrhythmias undergoing RF ablation | Patients with cardiac arrhythmias will be undergoing RF ablation using the Niobe Remote Magnetic Navigation System with CDS as their standard of care. System performance data will only be collected during the RF ablation procedure. Outcome measures will be evaluated with the CDS connected and without the CDS connected within all patients. Receives: Device: CDS box connection of the Niobe™ Remote Magnetic Navigation System |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mapping quality
Physician's and technician's subjective score of the quality of mapping the right atrium without CDS box connected and with CDS box connected
Measured: One day - during ablation procedure
Pacing thresholds
Pacing thresholds of three separate areas of the right atrium without CDS box connected and pacing thresholds of the same three areas with CDS box connected
Measured: One day - during ablation procedure
Pacing capture
Pacing capture of three separate areas of the right atrium without CDS box connected and pacing capture of the same three areas with CDS box connected
Measured: One day - during ablation procedure
Electrocardiograms
Difference between and disturbance of the intracardiac electrocardiograms without the CDS box connected versus with the CDS box connected, evaluated by two independent and blinded electrophysiologists
Measured: 10 months - ECGs will be evaluated after inclusion is completed
Secondary outcomes (3)
Number of procedure related major adverse events, attributed to the CDS system
Major adverse events: death, acute myocardial infarction (AMI) or coronary artery damage, major bleeding - type III and V, abdominal bleeding, tamponade > 80cm3, late tamponade, ischemic cerebral event
Measured: 30 days
Number of procedure related minor adverse events, attributed to the CDS system
Minor adverse events: post procedural precordial pain, phrenic nerve injury, minor bleeding - type II
Measured: 30 days
Number of acute procedure succes
Number of procedures with successful electrical isolation of ablated area
Measured: 1 day - during ablation procedure

Questions about this trial
What is this clinical trial studying?

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 3 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 2017. 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?
Mapping quality (time frame: One day - during ablation procedure). The study lists 4 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 2017; AzTrials last refreshed its copy on 7 Nov 2026.
