Robotic percutaneous coronary interventions have recently been introduced in the cardiac catheterization laboratory. Robotics offers benefits of greater precision for stent placement and occupational hazard protection for operators and staff. First generation systems were able to advance and retract coronary wires, balloons, and stents, but did not have guide control functions. The second-generation robotic system (CorPath GRX) has an active guide management function offering the ability to move guide catheters. Expanding utilization of robotics to perform diagnostic coronary angiography would further reduce radiation scatter exposure and other occupational hazards to operators. This approach is particularly appealing in the setting of radial access, as universal radial diagnostic catheters can engage both the right and left coronary arteries without exchange. We describe here, the first two cases of such a procedure with the CorPath GRX robotic system.
