Background: Benefits of PCI using the CorPath robotic system configured for transfemoral arterial access (TFA) have been demonstrated. The prevalence of transradial arterial access (TRA) in the U.S. is increasing but the feasibility and the success of robot-assisted PCI configured for TRA has not been investigated. Methods: Robotic PCI was utilized at a single center in consecutive, unmatched non-emergent PCI procedures. Technical success was completion of the robotic PCI without conversion to manual operation. Procedural success was PCI to <30% residual stenosis with no postprocedure MACE. Results: Robotic PCI was performed using TFA (32 procedures, 36 lesions) and TRA (36 procedures, 50 lesions). Patient and lesion characteristics were similar for TFA and TRA groups Table I. Multi-vessel PCI was performed in 13.9% of TRA group compared to 3% of TFA group (p=NS). No difference in technical (100% vs. 96%; p=NS) or procedural (100% vs. 96%; p=NS) success were seen. When corrected for number of lesions treated, TRA procedures continued to demonstrate longer total fluoroscopy time (14.24 vs. 10.13 min.; p=0.003) and procedure time (45.14 vs. 36.67 min.; p=0.009). No difference in contrast use was seen. No MACE events were reported in either group. Conclusion: Robotic-assisted PCI via TRA is feasible, safe and effective. Total fluoroscopy and procedure times were greater with TRA. Post-procedure MACE did not occur in either group. (Table Presented).
