To explain:
The heart murmur sound, which indicates aortic valve stenosis, and the heart murmur sound, which indicates aortic valve prolapse.
Given:
Heart valve stenosis impedes blood flow, whereas heart valve prolapse allows blood to flow backward (regurgitation). Both of these conditions can be detected as heart murmurs when a stethoscope is used to detect the proper heart sounds.
Introduction:
The heart is a muscular pump found in most of the animals. Its main function is to pump blood throughout the body. The heart has four chambers and these chambers are separated by valves. The blood flow is unidirectional through a normal heart because of the presence of these valves. If the valves work abnormally, then the blood flow becomes abnormal. It includes heart valve stenosis, which impedes blood flow, and heart valve prolapse, which results in backflow of blood. These conditions can be identified by abnormal heart sounds.
