Abstract

The use of the radial artery (RA) as a conduit for coronary artery bypass grafting (CABG) was initially proposed by the Carpentier group, and subsequently it has been the subject of numerous observational studies and of several randomized controlled trials (RCTs) [1–6]. The RA is relatively easy to harvest, can reach all the coronary territories without significant size mismatch with the coronary vessel and leads to few, if any, site-related complications. However, the RA’s medial layer is largely muscular, in contrast to the elastic internal lamina of the internal thoracic artery (ITA), which makes the RA more prone to spasm and atherosclerosis as well as more sensitive to competitive flow (Fig. 1).
