Any of the heart’s four valves can become damaged. It may happen because of conditions at birth or scarring from disease. A damaged valve can decrease the amount of blood that flows through it. This condition is called stenosis. Low blood flow can lead to heart failure and death. The valve will need to be opened to restore full blood flow.

Rheumatic fever and congenital birth defects are two main causes of stenosis. It can also happen due to aging and calcium deposits.

Depending on the overall condition of the valve, relief of symptoms can be expected to last at least 2 years. Some people have relief of symptoms much longer.
