Valve replacement replaces a failing valve with a healthy valve and is used for which diseases?

• A. It repairs a leaky valve
• B. It widens narrowed arteries
• C. It replaces the valve and is used for regurgitation or stenosis
• D. It removes the valve entirely

Answer: (C)

Valve replacement is used when a heart valve is diseased and can’t function properly, specifically when it becomes either stenotic (narrowed) or regurgitant (leaky). Replacing the valve with a healthy prosthetic one restores normal blood flow and reduces strain on the heart. This isn’t about repairing a valve that leaks—that would be valve repair—not about widening arteries, which is a different procedure, and it’s not about removing the valve without replacement. So the indication is regurgitation or stenosis.
