What does CABG refer to in the field of cardiac surgery?

CABG stands for Coronary Artery Bypass Graft, which is a surgical procedure used to treat coronary artery disease. In this operation, a surgeon takes a blood vessel from another part of the body and uses it to create a new pathway for blood to flow to the heart. This bypasses the blocked or narrowed segments of the coronary arteries, leading to improved blood flow and oxygen delivery to the heart muscle.

The other options presented—such as the angioplasty balloon graft or coronary artery biopsy guide—do not accurately reflect this well-established surgical procedure and instead represent either a different method of treatment or an unrelated medical term. Understanding CABG is crucial for grasping cardiac care and the management of coronary artery disease, highlighting its significance in improving patient outcomes in cardiac surgery.
