The many and various diseases of the heart valves generally lead to either or both stenosis and/or regurgitation. Stenosis is where an obstruction is caused, it can be by a number of things but when the valves are At Fault is is usually because they either go stiff and block blood flow or they seel up again blocking blood flow. Regurgitation is when there is s defect in the valve that allows blood to flow back into the previous chamber. This can be in the form of eother a hole in one of the leaflets of the valve or an area where they do not meat correctly. In either situation the blood flow in the correct direction is limited and so the heart must work harder to compensate.

∙ 10y agoThe Bicuspid valve of the heart helps in contraction and the Semi Lunar valve helps in relaxation. Basically, that creates the "Lub" and "Dub" sound. If the valves stop working the heart muscle will also stop working. Which can lead to death. Therefore, valves help in the contraction and relaxation of heart as well as it prevents the backflow of blood to the heart again.
