Summary
A new remote catheter navigation system (RCNS) offers a safe and effective way to reduce radiation exposure for interventionalists during cardiac arrhythmia procedures. Navigation times were comparable to traditional methods.
Area of Science:
- Cardiovascular Interventions
- Medical Imaging
- Radiation Safety
Background:
- Interventionalists face significant radiation exposure during catheter-based cardiac arrhythmia procedures.
- A prototype Remote Catheter Navigation System (RCNS) was developed to mitigate occupational radiation dose.
- This study evaluates the safety and feasibility of the RCNS in vivo.
Purpose of the Study:
- To assess the safety and feasibility of a novel RCNS.
- To compare remote navigation with conventional techniques for cardiac catheterization.
- To evaluate the impact of RCNS on occupational radiation exposure.
Main Methods:
- Seven anatomical targets in porcine right hearts were used.
- An experienced electrophysiologist navigated a radiofrequency ablation catheter using both RCNS and conventional methods.
- Success rates, navigation times, radiation exposure, and procedure times were recorded.
Main Results:
- All targets were successfully reached with both navigation methods.
- The RCNS demonstrated no erratic catheter motion.
- Navigation method had minimal impact on navigation time and exposure metrics.
Conclusions:
- The RCNS appears to be a safe method for reducing occupational radiation dose.
- Remote navigation using the RCNS offers navigation times comparable to conventional bedside navigation.
- The RCNS shows promise for improving safety in electrophysiology interventions.
