Over time, ruptured plaque also hardens and narrows the coronary arteries. CABG is one treatment for CHD. During CABG, a healthy artery or vein from the body is connected, or grafted, to the blocked coronary artery. The grafted artery or vein bypasses (that is, goes around) the blocked portion of the coronary artery. This creates a new path for oxygen-rich blood to flow to the heart muscle. Surgeons can bypass multiple coronary arteries http://www.nhlbi.nih.gov/health/health-topics/topics/cabg during one surgery.

[14] Percutaneous (per-ku-TA-ne-us) coronary intervention (PCI), commonly known as coronary angioplasty (AN-jee-oh-plas-tee) or simply angioplasty, is a non-surgical procedure used to open narrow or blocked coronary (heart) arteries. Percutaneous means "through the skin." The procedure is done by inserting a thin flexible tube (catheter) through the skin in the upper thigh or arm in the artery. The procedure restores blood flow to the heart muscle. xxxx PCI can restore blood flow to the heart. During the procedure, a thin, flexible catheter (tube) with a balloon at its tip is threaded through a blood vessel to the affected artery. Once in place, the balloon is inflated to compress the plaque against the artery wall. This restores blood flow through the artery. Doctors may use the procedure to improve symptoms of CHD, such as angina. The procedure also can reduce heart muscle damage caused by a heart attack. http://www.nhlbi.nih.gov/health/health-topics/lopics/angioplasty Accessed July 22, 2015 from the National Heart, Lung, and Blood Institute (NHLBI), National Institute of Health (NTH), Department of Health and Human Services of the Government of the United States of America.
