What is the surgical bypass operation performed to shunt blood around an obstructed coronary artery called?

• A. Angioplasty
• B. Angiography
• C. Coronary Artery Bypass Graft
• D. Coronary Bypass

Answer: (D)

The main idea here is naming the operation that reroutes blood around a blocked coronary artery. This surgical bypass uses a graft from another vessel to create a new path for blood to reach the heart muscle, bypassing the obstructed segment. While the formal name is coronary artery bypass grafting, it is commonly referred to simply as a coronary bypass. This term directly conveys the idea of creating a bypass around the blockage.

Angioplasty is a catheter-based procedure to open a narrowed artery with a balloon or stent, not a bypass. Angiography is just an imaging test to visualize the arteries. Coronary Artery Bypass Graft is the formal name of the procedure, but the everyday shorthand used in many contexts is coronary bypass, which is why that option is the best fit.
