What is the internal mammary artery bypass?
The internal mammary artery (IMA) is the preferred conduit for bypassing the left anterior descending (LAD) artery in patients undergoing coronary artery bypass grafting. Systematic evaluation of the frequency and predictors of IMA failure and long-term outcomes is lacking.
Why is internal thoracic artery used for bypass?
Introduction. The internal thoracic artery (ITA), namely, the left ITA (LITA), is arguably the most vital conduit for the conduct of coronary artery bypass grafting (CABG) due to its superior long-term patency and mortality benefit.
Which vein artery is commonly used for bypass surgery?

But when more than one bypass graft is needed, most surgeons use a saphenous vein from the leg.
