I've been diagnosed with a heart murmur. What does this mean?
assistant
A heart murmur is a sound heard during an echocardiogram or other medical test that indicates a problem with the heart's valves. It can be caused by a variety of conditions, including birth defects, infections, and damage to the heart muscle. If you have a murmur, your doctor will likely recommend further tests to determine its cause and how best to treat it.
