Normally, heart murmurs do not require treatment unless they are caused by another condition, states the National Heart, Lung, and Blood Institute. The majority of heart murmurs are harmless, however, conditions such as anemia and congenital heart defects can cause more serious heart murmurs.
According to the American Heart Association, innocent (harmless) heart murmurs are the sounds made by the blood circulating through the heart. In fact, heart murmurs in children are common and usually disappear when the child reaches adulthood.
Although most heart murmurs are innocent, those caused by anemia and congenital heart defects do require treatment, according to the National Heart, Lung, and Blood Institute. While iron and diet changes can often treat anemia, claims WebMD, congenital heart defects may need surgery and certain medication, states the National Heart, Lung, and Blood Institute.
Heart murmurs caused by congenital heart defects, such as infected heart valves, require antibiotics, while structurally damaged heart valves require surgery, claims MedicineNet. However, the majority of congenital heart defects, such as heart murmurs, can either be easily fixed or do not require any treatment, states the American Heart, Lung, and Blood Institute. Nevertheless, those with heart defects must monitor the condition regularly throughout their life.
