Outcomes of total arterial revascularization vs conventional revascularization in patients undergoing coronary artery bypass graft surgery: A narrative review of major studies
Coronary artery bypass grafting (CABG) is a widely used surgical procedure which improves clinical outcomes in appropriately selected patients. Conventionally, the greater saphenous vein is often used in CABG. However, due to their higher long-term patency rates, arterial conduits are routinely used, with the left internal thoracic artery (LITA) on left anterior descending (LAD) being the gold standard in CABG. Our aim in the present work was to investigate the outcomes of a total arterial grafting (TAG) on the whole heart, with no use of venous grafts, compared to mixed conduits in real-world data. A literature search was conducted in the bibliographic databases PubMed and Web of Science. Only studies comparing TAG with conventional CABG (at least one venous graft plus one or more arterial grafts), with at least one hundred patients in each group were included in this review. After study selection, a total of 15 relevant studies were evaluated and discussed in the present review. Results indicated that TAG is a highly efficient technique, and multiple arterial grafts can be used to reliably revascularize all coronary artery territories. TAG was more beneficial in terms of both short and long-term outcomes and its use should be encouraged. Large randomized clinical trials are needed to confirm the superiority of total arterial grafting with regard to long-term outcomes.
