Your heart has four valves. Normally, these valves open to let blood flow through or out of your heart, and then shut to keep it from flowing backward. But sometimes they don't work properly. What can happen?
Valve problems can be present at birth or caused by infections, heart attacks, or heart disease or damage. Some valve problems are minor and do not need treatment. Others might require medicine, medical procedures or surgery to repair or replace the valve.
