My doctor says I have a heart murmur, but I don't feel any different. What is a heart murmur?

A heart murmur is a sound made by the turbulent blood flow through your heart valves. It can be caused by a variety of conditions, including congenital heart defects, valve disease, and inflammation of the heart muscle. If you hear a murmur, it could mean that one of these conditions is present.
