Objectives:
The PRECISE multi-center study demonstrated the safety and feasibility of robotic-enhanced coronary intervention (PCI). We studied the learning curve associated with the robotic PCI approach.
Methods:
The CorPath 200 robotic system was used to perform clinically indicated PCI. The first 3 cases performed by each interventional cardiologist were considered early-experience cases and subsequent procedures were regarded as advanced-experience cases. We compared procedure efficiency, patient radiation exposure, and clinical outcomes in early and advanced-experience cases.
Results:
A total of 164 robotic-enhanced PCI procedures were performed, with 60 early-experience cases. Advanced-experience cases were associated with shorter procedure duration (51.3 ± 25.5 min vs. 42.2 ± 16.4 min, P = 0.008) and fluoroscopy time (12.9 ± 7.8 min vs. 10.1 ± 4.8 min, 0.009) as compared to early-experience cases.
Conclusions:
After performing 3 cases, interventionalists were able to complete robotic-enhanced PCI faster, with reduced radiation, and without compromising safety. The steep learning curve highlights the easy adoption of remote-control robotic technology for PCI.
