Despite a decrease in utilization rate during the last decade,1 more than 400 000 coronary artery bypass graft (CABG) surgery procedures were performed in 2009.2 It has been one of the most extensively studied major surgical procedures, with particular attention paid to mortality, morbidity, and quality of life. The majority of CABG surgeries use both arterial and saphenous vein grafts. The choice and quality of the conduit used for the bypass conduit plays a major role in short-term and long-term outcomes.3
