Stenosis refers to which of the following?

Explanation:
Stenosis means a valve opening is narrowed, so it can’t open fully and forward flow is restricted. That makes the description of valves unable to open completely the best way to capture the essence of stenosis. In contrast, a valve that leaks backward when it should be closed describes regurgitation or insufficiency, not stenosis. And saying a valve becomes calcified but remains open doesn’t reflect the core issue of stenosis, which is a reduced opening rather than a merely partly open valve due to calcification.
