'''Coronary Artery Bypass Graft''', also known as '''CABG''', is a common cardiac surgery procedure in which vein or artery is used as a conduit and is either grafted from the aorta (or if using left internal mammary artery, used in situ) to a coronary artery beyond a blockage in the vessel, with goal of improving blood flow to the heart, i.e. surgical coronary re-vascularization. The left internal mammary artery (LIMA) is considered first choice of graft due to high patency rate of > 90% at 10 years, though saphenous vein grafts are often used as well. It is most often indicated for individuals with significant multi-vessel Coronary Artery Disease, in particular those with Diabetes Mellitus or left main coronary vessel disease; it can also be used on a more emergent basis for those with Acute Coronary Syndrome and ST-Elevation Myocardial Infarction cases that are refractory to PCI or maximal medical management. It can be described by the number of vessels to be bypassed (single, double, triple, quadruple) as well as the technique (traditional on-pump, off-pump or minimally invasive direct). | |||

Coronary Artery Bypass Graft, also known as CABG, is a common cardiac surgery procedure in which vein or artery is used as a conduit and is either grafted from the aorta (or if using left internal mammary artery, used in situ) to a coronary artery beyond a blockage in the vessel, with goal of improving blood flow to the heart, i.e. surgical coronary re-vascularization. The left internal mammary artery (LIMA) is considered first choice of graft due to high patency rate of > 90% at 10 years, though saphenous vein grafts are often used as well. It is most often indicated for individuals with significant multi-vessel Coronary Artery Disease, in particular those with Diabetes Mellitus or left main coronary vessel disease; it can also be used on a more emergent basis for those with Acute Coronary Syndrome and ST-Elevation Myocardial Infarction cases that are refractory to PCI or maximal medical management.
