Total Arterial Revascularization (TAR) in Coronary Artery Bypass Grafting (CABG) is an advanced surgical technique that exclusively uses arterial grafts to restore blood flow to the heart. Unlike conventional CABG, which often utilizes a combination of arterial and venous grafts, TAR relies entirely on arteries, such as the left and right internal mammary arteries (LIMA and RIMA), the radial artery, and sometimes the gastroepiploic artery.
Arterial grafts are preferred over veins due to their superior long-term patency, resistance to atherosclerosis, and enhanced durability. Studies have shown that patients undergoing 100% Total Arterial Revascularization experience better long-term outcomes, including reduced risk of graft failure, fewer repeat interventions, and improved survival rates compared to those receiving venous grafts.
This approach is particularly beneficial for younger patients and those with multi-vessel coronary artery disease. However, it requires advanced surgical expertise and precise patient selection to ensure the best outcomes. Many leading cardiac centers and specialized surgeons now advocate for TAR as the gold standard in coronary bypass surgery, promoting better heart health and longevity for patients.
