Multi-arterial Coronary Grafting

Arterial conduits, especially the internal thoracic arteries (ITAs), are rarely affected by intimal hyperplasia or atherosclerosis, major contributors to early and late vein graft failure. Improved survival and freedom from reintervention with multi-arterial grafting (MAG) are reported in large observational studies, particularly when they supply more than one anatomically important coronary territory.Several grafting configurations are possible depending on conduit and target characteristics, with the left ITA to the left anterior descending (LITA-LAD) typically being the cornerstone around which the rest of the conduits are constructed.
