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.

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.

RECRUITINGAccuracy 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.
