Abstract Despite good outcomes, the use of the radial artery as a coronary graft is not widespread. Concerns regarding its low versatility and the risk of hand ischaemia, as well as the lack of reliable information regarding the best storage solution of the graft, and regarding the treatment for preventing spasms have limited its use. In this manuscript, the (numerous) benefits and (few) drawbacks of the proximal inflow for the radial artery from the in situ right internal thoracic artery proximal stump are discussed. Outcomes are reported from a limited series of patients undergoing totally arterial myocardial revascularization using this composite graft and both internal thoracic arteries.

Abstract OBJECTIVES To compare different configurations of the bilateral internal thoracic arteries for the left coronary system and examine early and late outcomes, including mid-term graft patency. METHODS We reviewed 877 patients who underwent primary isolated coronary artery bypass grafting using in situ bilateral internal thoracic arteries [in situ right internal thoracic artery (RITA)-to-left anterior descending artery (LAD) grafting, n = 683; in situ left internal thoracic artery (LITA)-to-LAD grafting, n = 194]. We compared mid-term patency between the grafts. Propensity score matching was performed to investigate early and long-term outcomes. RESULTS The 2-year patency rate for RITA-to-LAD and LITA-to-LAD grafts were similar. Multivariate analysis revealed that RITA-to-non-LAD anastomosis (P = 0.029), postoperative length of stay (P = 0.003) and chronic obstructive pulmonary disease (P = 0.005) were associated with graft failure. After statistical adjustment, 176 propensity-matched pairs were available for comparison. RITA-to-LAD grafting enabled a more distal anastomosis. Kaplan–Meier analysis revealed that the incidences of death, repeat revascularization and myocardial infarction were significantly higher in the LITA-to-LAD group among both the unmatched and matched samples (P = 0.045 and 0.029, respectively). CONCLUSIONS The mid-term patency and outcomes of RITA-to-LAD grafting are good and reduces future cardiac event, in contrast to LITA-to-LAD grafting.
