Four patients received a single RITA, in addition to venous graft(s) in the ‘single’ cohort.
CABG: coronary artery bypass grafting; LAD: left anterior descending artery; LITA: left internal thoracic artery; MAG: multiple arterial grafts; RITA: right internal thoracic artery; SAG: single arterial graft.
