Stenosis is defined as:

Stenosis is defined as:

• A. Abnormal Heart Sounds
• B. Dilation of Arteries
• C. Inflammation of the Pericardium
• D. Narrowing, Stricture

Answer: (D)

Stenosis means narrowing or constriction of a passage, such as a heart valve or a blood vessel. This narrowing makes it harder for blood to pass through, which can raise pressure before the narrowed point and reduce flow beyond it. It’s not dilation (enlargement) of an artery, which would be a different process, nor is it inflammation of the pericardium. Abnormal heart sounds can be heard with stenosis, but they’re signs of the condition rather than its definition. So the essence is a narrowing or stricture that impedes flow.
