Question

The figure given shows an angioplasty of the coronary blood vessel. Which one of the following statements correctly describes what is being done?

• A. It is the coronary artery which has a cancerous growth that is being removed.
• B. It is the coronary artery that is blocked by a plaque, and the same is being cracked.
• C. It is the coronary vein in which the defective valves are being opened.
• D. It is coronary vein blocked by a parasite (blood fluke) that is being removed.

Answer 1

The correct option is B It is the coronary artery that is blocked by a plaque, and the same is being cracked.

The figure refers to the procedure of angioplasty. Here atherosclerotic plaque, which builds up and clogs the coronary arteries, is compressed against the vessel wall by expanding a balloon-like device inserted through a catheter that has been threaded through the artery.

Therefore, the correct answer is option B.
