Coronary artery bypass graft surgery (CABG) is recommended for patients with obstructive coronary artery disease whose survival will be improved compared to medical therapy or percutaneous coronary intervention (PCI). In addition, patients with angina refractory to medical therapy may receive a recommendation for CABG if PCI cannot be performed. The procedure involves the construction of one or more grafts between the arterial and coronary circulations. Most patients receive both arterial and venous grafts during CABG and long-term graft patency is significantly better with the former. Potential consequences of graft failure (loss of patency) include the development of angina, myocardial infarction, or cardiac death.
This topic will briefly discuss the causes of graft failure and rates of patency for the various coronary bypass grafts. The following issues are discussed elsewhere:
●Operative mortality. (See "Operative mortality after coronary artery bypass graft surgery".)
●Early noncardiac complications. (See "Early noncardiac complications of coronary artery bypass graft surgery".)
●Early cardiac complications. (See "Early cardiac complications of coronary artery bypass graft surgery".)
