Study summary

The introduction of real-time MRI-guided cardiac ablation therapy, a significant advancement in interventional medicine, necessitates precise catheter tracking for accurate navigation within the complex cardiac anatomy. The introduction of the NorthStar software as an active tracking system holds promise for improving the precision and efficiency of catheter manipulation during these procedures. However, a rigorous evaluation of its accuracy and reliability in a clinical setting is crucial to validate its viability.

The objective of this study is to evaluate the accuracy of catheter localization using the NorthStar software during real-time MRI-guided cardiac ablation therapy.

    Northstar

    This is the study group

    Device: NorthStar

Interventions

  • DeviceNorthStar

    Throughout the real-time MRI-guided ablation procedure, the operator will assess the precision of the NorthStar 3D navigation software. Before commencing the actual ablation, the operator will confirm the alignment of the 3D anatomical shell, generated in NorthStar through specific electrical signals. Post the ablation procedure, a secondary alignment verification will be conducted to detect any potential drift or shift.

What researchers measure

Primary outcomes

  1. Accuracy of Catheter Localization

    The primary objective of this study is to evaluate the accuracy of catheter localization using the NorthStar software during realtime MRI-guided cardiac ablation therapy. At the start of the procedure, the catheters will be manoeuvred to the predefined areas within the right side of the heart based on the specific electrical signals in that area. These locations will be virtually marked within the NorthStar software. The extent to which these markers maintain their spatial coordinates after the ablation procedure, evaluated by obtained electrical signals, will serve as a quantitative measure of the system's accuracy.

    Time frame: during procedure

Secondary outcomes

  1. Influences of breathing pattern

    To investigate the influence of breathing pattern on the accuracy of catheter localization. The breathing pattern during the procedure will be monitored and any changes will be related to the accuracy of catheter localization

    Time frame: during procedure

  2. Influences of procedure duration

    To investigate the influence of procedure duration on the accuracy of catheter localization.

    Time frame: during procedure

  3. Influences of complications during ablation

    To investigate the influence of complications during ablation on the accuracy of catheter localization. Complications during the procedure will be registered and categorized.

    Time frame: during procedure

  4. Influences of patient characteristics

    To investigate the influence of patient characteristics on the accuracy of catheter localization. Standard patient characteristics will be noted such as BMI, cardiac output and heartrate to investigate if these characteristics will influence the catheter localization.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2024 (actual). Primary completion is estimated for Jan 2025, 12 months after the start.

Of 55 interventional studies with no phase under Atrial Flutter, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 63. This study's planned 12 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 11, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
