For over a decade there has been accumulating evidence that the use of more than a single arterial graft during coronary artery bypass grafting can improve clinical outcomes. However the vast majority of patients in most developed countries still only receive a single arterial conduit even in the presence of multivessel coronary artery disease. This review summarizes the current evidence for the use of a second internal mammary artery and/or radial artery graft. While in comparison to vein grafts the superior patency of internal mammary artery grafts is well established, there now exists strong and consistent evidence of the superior patency of radial arteries over the longer term. Likewise, there is a rapidly growing body of evidence that the superior patency of both these arteries in comparison to vein grafts translates into improved clinical outcomes.
