What Is a Coronary Bypass?
A coronary bypass is a venous graft which bypasses a clogged section of one of the coronary arteries to supply the heart with oxygenated blood. The process of creating the graft is known as a coronary bypass surgery, and it is a major surgery, performed by a cardiovascular surgeon. This surgery is recommended to patients when treatments for angina appear to be ineffective, or when there are other signs that a clogged coronary artery is posing a health risk.
