BACKGROUND: Robotic percutaneous coronary intervention (R-PCI) has been shown to benefit the operator but has not shown any significant benefit to the patient. We sought to compare a large cohort of R-PCI to traditional percutaneous coronary intervention (PCI) procedures performed at a tertiary care center in the same time frame. METHODS: A total of 996 consecutive patients referred for PCI between December 2017 and March 2019 were studied, of which 310 (31.1%) patients were selected to undergo R-PCI and 686 (68.9%) patients underwent traditional PCI. The coprimary study outcome measures were air kerma, dose-area product, fluoroscopy time, volume of contrast, and total procedural time. Caliper propensity-matching technique was used (caliper, 0.05) to match each R-PCI patient to the nearest traditional PCI patient without replacement. RESULTS: Air kerma (mGy; median [interquartile range]; P; 884 [537-1398] versus 1110 [699-1498]; P=0.002) and dose-area product (cGycm2; 4734 [2695-7746] versus 5746 [3751-7833]; P=0.003) were significantly lower in the R-PCI group. There was no difference in fluoroscopy time (minutes; 5.51 [3.53-8.31] versus 5.48 [3.31-9.37]; P=0.936) and contrast volume (mL; 130 [103-170] versus 140 [100-180]; P=0.905). Total procedural time (minutes) was significantly higher in the R-PCI group (27 [21-40] versus 37 [27-50]; P<0.0005). CONCLUSIONS: R-PCI is associated with a significant decrease in radiation exposure to the patient with no increase in fluoroscopy time, as well as contrast utilization, and a minor increase in procedure duration compared with traditional PCI.
