Total Arterial vs. Mixed Grafting in Left Coronary CABG

Coronary artery bypass grafting using only arterial conduits in the left coronary artery system. The left internal thoracic artery (LITA) is grafted to the LAD, and the radial artery is anastomosed to the obtuse marginal or diagonal branches. This approach avoids the use of saphenous vein grafts for the left coronary system.

A standard coronary artery bypass grafting (CABG) procedure where the left internal thoracic artery (LITA) is grafted to the LAD, and saphenous vein grafts are used for the obtuse marginal or diagonal branches of the left coronary system. This approach represents the conventional mixed arterial-venous strategy.
