Internal mammary artery grafts demonstrate superior long-term patency and survival compared to saphenous vein grafts due to a striking resistance to atherosclerosis and unique endothelial properties.
Understanding the molecular and structural resistance of the internal mammary artery to atherosclerosis reinforces its use as the first-line conduit for coronary artery bypass grafting.

IMA use in CABG may improve outcomes; leaves open need for contemporary randomized confirmation.
Otsuka et al. (2013) conducted a review in Coronary artery disease. Internal mammary artery (IMA) graft vs. Saphenous vein graft (SVG) was evaluated. Internal mammary artery grafts demonstrate superior long-term patency and survival compared to saphenous vein grafts due to a striking resistance to atherosclerosis and unique endothelial properties.
