Robotic-assisted transradial diagnostic coronary angiography

Area of Science:

• Cardiovascular medicine
• Medical robotics
• Interventional cardiology

Background:

• Robotic-assisted percutaneous coronary interventions (PCI) are emerging in cardiac catheterization labs.
• Current systems offer enhanced precision in stent deployment and protect staff from radiation.
• First-generation systems lacked guide catheter control, limiting their functionality.

Observation:

• The second-generation CorPath GRX system introduces active guide management, allowing for precise movement of guide catheters.
• This advancement enables the potential expansion of robotics to diagnostic coronary angiography.
• The study details the first two cases utilizing the CorPath GRX for this purpose.

Findings:

• The CorPath GRX system successfully performed diagnostic coronary angiography.
• The active guide management feature facilitated catheter engagement in both right and left coronary arteries.
• This approach demonstrated feasibility, particularly with radial access, avoiding catheter exchanges.

Implications:

• Expanding robotic use to diagnostic angiography can significantly reduce operator radiation exposure and occupational hazards.
• The system's capabilities are particularly advantageous in radial access procedures.
• This represents a significant step towards safer and more efficient cardiac catheterization procedures.
