Abnormal heart sounds called murmurs are usually a result of faulty valves. For example, an incompetent valve fails to close tightly, so that blood leaks through the valve when it is closed. Another example, an incompetent bicuspid valve produces a swishing sound immediately after the first heart sound.

∙ 13y agoThere are two types of heart murmurs; innocent and abnormal.
Innocent murmurs are common and harmless. They can be caused by pregnancy, fever, or even physical activity.
Abnormal heart murmurs are much more serious. They are most commonly caused by congenital Heart disease, which may be something like a cardiac shunt or a hole in the heart. However, abnormal murmurs can also be caused by infections such as endocarditis.
