Procedural and one-year outcomes of robotic-assisted versus manual percutaneous coronary intervention

BACKGROUND: Robotic-assisted percutaneous coronary intervention (rPCI) has proven to be feasible and safe. Comparative analyses of rPCI versus manual PCI (mPCI) are scarce. AIMS: We aimed to investigate procedural aspects and outcomes of rPCI using the second-generation CorPath GRX Vascular Robotic System compared with mPCI in patients with chronic coronary syndrome and non-ST-segment elevation myocardial infarction acute coronary syndrome. METHODS: From January to April 2021, 70 patients underwent rPCI at the University Heart p=0.78) was comparable between rPCI versus mPCI. During the PCI procedure, total contrast fluid volume did not differ, whilst longer fluoroscopy times (20.4 min 13.8-27.2 vs 14.4 min 10.4-24.3; p=0.001) were documented in the rPCI versus mPCI cohort. After 12 months of follow-up, neither all-cause mortality (p=0.22) nor MACE (p=0.25) differed between the groups. CONCLUSIONS: rPCI was associated with longer fluoroscopy times compared with mPCI, though without increased use of contrast medium. One-year follow-up revealed no differences in all-cause mortality or MACE, supporting the safety of a robotic-assisted approach.
