Arterial grafting, particularly with the radial artery, is associated with improved long-term clinical outcomes and patency compared to saphenous vein grafts in CABG.
Radial artery use lowers long-term MACE and boosts patency versus SVG; reinforces arterial conduit preference in multivessel CABG.
Coronary artery bypass grafting (CABG) is foundational to managing multivessel coronary artery disease. The internal thoracic artery (ITA) remains the gold standard for left anterior descending artery (LAD) grafting. Although saphenous vein grafts (SVGs) may be considered for non-LAD targets, the right ITA (RITA) and radial artery (RA) are associated with improved outcomes1 and thus are more commonly used for CABG. A recent systematic review and a network meta-analysis of 150,000 patients2,3 highlighted that the use of RA was associated with a lower risk of major adverse cardiovascular events (MACE) at 5 and 10 years and with a higher rate of patency at 5 years.
