Abstract: Background: Radial arteries (RA) are often preferred over saphenous veins as coronary artery bypass graft (CABG) conduits due to better long-term outcomes. However, there is limited evidence on the mechanisms of RA graft failure or outcomes after RA graft PCI (RA-PCI). We aimed to review temporal trends, procedural variables, and outcomes to explore the feasibility and safety of RA-PCI and report the characteristics of RA graft failure. Methods: Consecutive patients who underwent PCI post CABG between 2005–2018 were included, with yearly comparisons for trends. RA-PCI was compared to SVG-PCI. Results: A total of 2,780 PCIs were performed on patients following CABG: 86 to the RA and 716 to the SVG. Over 12 years, RA and native vessel PCI increased, SVG-PCI declined, and internal mammary PCI rates were consistently low (p<0.001). Conclusions: Our study showed RA-PCI is safe and feasible, with a trend to better outcomes compared to SVG-PCI. Different clinical presentations and angiographic variables suggest unique mechanisms of RA graft failure. Further studies are needed to investigate the underlying pathophysiology, which may have therapeutic implications.
