What is the name of the procedure that bypasses blocked coronary vessels using a graft?

• A. Coronary Artery Bypass Graft
• B. Heart Valve Replacement
• C. Cardiac Pacemaker
• D. Angioplasty

Answer: (A)

Bypass surgery uses a graft to create a new route for blood around a blocked coronary artery, restoring blood flow to the heart muscle. A graft from another vessel, such as a leg vein or chest artery, is connected to the aorta and to the coronary artery beyond the blockage, forming a detour that bypasses the narrowed segment. This improves oxygen delivery to heart tissue and can relieve angina and improve outcomes when coronary arteries are severely blocked. This is different from angioplasty, which opens a vessel at its site with a balloon or stent; heart valve replacement, which fixes a faulty valve; and a cardiac pacemaker, which helps regulate heart rhythm. The name of the procedure is Coronary Artery Bypass Graft.
