Question

Heart murmurs caused by a stenotic mitral valve ______.Choose the correct answer:A) are heard as a high pitched click when the valve should be—but is not—wide open during systole.B) are detected due to the turbulent blood flow that occurs as blood backflows into the left atrium C) are detected if the valve's cusps are thin and flexibleD) All of the listed responses are true.

Answer 1

Answer:

OptionA,   re heard as a high pitched click when the valve should be—but is not—wide open during systole.

Explanation:

Heart murmurs are sound that are heard when the blood flow into the left ventricle but the flow get reduced as compared to the normal flow. The flow reduction happens because of the stenotic valve which has a narrow opening as compared to the opening in valves of a normal heart. Due to reduced valve size, the blood flow becomes fast and turbulent thereby producing murmur sound.

Hence, option A is correct
