Clinical significance: Coronary artery bypass grafting (CABG) remains the gold standard treatment for patients with multi-vessel coronary artery disease. Despite the proposed benefits of multiple arterial grafts, autologous saphenous vein grafts (SVGs) are still the most frequently used bypass conduits in CABG. Progressive SVG failure after CABG remains a key limitation to the long-term success of surgery. Objective: Coronary artery bypass grafting (CABG) remains the gold standard treatment for patients with multi-vessel coronary artery disease. Despite the proposed benefits of multiple arterial grafts, autologous saphenous vein grafts (SVGs) are still the most frequently used bypass conduits in CABG. Progressive SVG failure after CABG remains a key limitation to the long-term success of surgery. Study design: Prospective, multi-center, randomized, within-subject-controlled , trial, enrolling patients with multi vessel atherosclerotic coronary artery disease, scheduled to undergo SVG CABG with arterial grafting of IMA to LAD and two or more saphenous vein grafts. In each patient, one SVG bypass will be randomized to be supported by the VEST, while another will not be supported and serve as control. Thus, the full cohort will provide a basis for comparison between two sets of SVGs: A VEST supported set; and an unsupported set.
