Coronary artery bypass
Coronary Artery Bypass
Coronary artery bypass (pronounced: kuh-ROH-nuh-ree AR-teh-ree BYE-pass), also known as Coronary Artery Bypass Graft (CABG, pronounced: CAB-gee), is a surgical procedure to improve blood flow to the heart.
Etymology
The term "coronary" comes from the Latin corona, meaning crown, referring to the crown-like appearance of the arteries surrounding the heart. "Bypass" refers to the process of creating a new pathway for blood flow.
Procedure
In a coronary artery bypass, a healthy blood vessel is taken from another part of the body, such as the leg, arm, or chest, and connected to the coronary arteries above and below the narrowed area or blockage. This new pathway allows blood to bypass (go around) the blocked part of the coronary artery, hence the name "bypass."
