A stenosed pulmonary semilunar valve slows the movement of blood into the artery that leads to the lung.

Question

Quizplus · Accepted Answer

Stenosis of the pulmonary semilunar valve leads to a narrowing of the valve opening, which decreases the amount of blood that can flow out of the right ventricle and into the pulmonary artery. This can cause the heart to work harder to pump blood and can lead to symptoms such as shortness of breath and fatigue.
