A novel robotic catheter control system (CCS) significantly improved navigation and precision targeting times in cardiac procedures. This robotic system shows promise for enhanced remote catheter manipulation in future cardiac surgeries.

Area of Science:

  • Cardiovascular Surgery
  • Medical Robotics
  • Catheter Ablation

Background:

  • Robotic-assisted surgery is increasingly used in cardiac procedures, offering potential benefits in instrument precision, stability, and remote control.
  • Early experience with a novel remote robotic catheter control system (CCS) is reported.

Purpose of the Study:

  • To evaluate the feasibility and performance of a novel computerized robotic catheter control system (CCS).
  • To assess the system's ability for precise, rapid, and repeatable catheter manipulation within the heart.
  • To compare the robotic system's navigation and precision capabilities against a standard catheter system.

Main Methods:

  • A computerized robotic catheter control system enabling precise 3D remote manipulation was used.

Related Experiment Videos

  • System performance was tested in 12 ex-vivo porcine hearts, assessing navigation and precision targeting.
  • Comparison was made with a standard quadripolar steerable ablation catheter in a deflectable sheath.

    • Main Results:

    • The robotic CCS significantly reduced navigation time (8.5 sec vs. 22.7 sec, p=0.002).
    • Precision targeting time was also significantly decreased with the CCS (10.1 sec vs. 29.6 sec, p<0.001).
    • These improvements were observed in specific right and left atrial sites in ex-vivo models.

    Conclusions:

    • A computerized robotic catheter control system is feasible for cardiac procedures.
    • The system demonstrates potential for rapid and precise catheter movement.
    • Further in-vivo studies are required to determine its role in patient-specific catheter ablation and mapping.
