Which condition is characterized by inflammation and narrowing of the aortic valve?

• A. Aortic regurgitation
• B. Heart block
• C. Aortic valve stenosis
• D. Rheumatic fever

Answer: (C)

Aortic valve stenosis is characterized by the inflammation and narrowing of the aortic valve, which restricts blood flow from the heart into the aorta during systole. This condition can be caused by congenital defects, age-related calcification of the valve, or rheumatic fever, leading to a stiffened valve that does not open fully. As a result, the heart has to work harder to pump blood through the narrowed opening, which can lead to various symptoms such as shortness of breath, chest pain, and fatigue. Other conditions mentioned, like aortic regurgitation, involve the improper closure of the valve rather than its narrowing, leading to backflow of blood rather than obstructed forward flow. Heart block pertains to electrical conduction issues affecting the heart's rhythm rather than structural changes to the valves. While rheumatic fever can contribute to aortic valve stenosis through inflammation, it does not specifically define the narrowing of the valve itself. Thus, aortic valve stenosis is the most accurate and specific term for the condition described in the question.
