Question

Which type of the following heart valves are generally damaged?

• A. Tricuspid valve
• B. Eustachian valve
• C. Bicuspid valve
• D. Aortic semilunar valves

Answer 1

Answer: (D)

Aortic semilunar valves

Valves are the membranous structure which helps to stop the backflow of the blood. These are very delicate and may get rupture in case of hypertension or irregular flow of blood inside the heart.

There are two prototypical processes that can affect the aortic valve - aortic stenosis in which the valve fails to open fully, thereby obstructing blood flow out from the heart, and aortic insufficiency, also called aortic regurgitation, in which the aortic valve is incompetent and blood flows passively back to the heart in the wrong direction. These two conditions frequently co-exist. Common causes of aortic regurgitation include vasodilation of the aorta, previous rheumatic fever, infection, i.e., infective endocarditis, degeneration of the aortic valve, and Marfan's syndrome. The most common congenital abnormality of the heart is the bicuspid aortic valve.

So, the correct answer is option D.
