Heart valve problems are usually heard as clicks and murmurs that
your doctor distinguishes by listening to different parts of the chest.
Depending on the location of the clicks and murmurs, your doctor will be able
to determine the specific valve problem(s) and if necessary will confirm this
with an echocardiogram.
There are very few differences between some sounds. For example,
aortic valve stenosis and mitral valve regurgitation can sound very similar,
and they can also mask tricuspid stenosis. As a result, if your doctor hears
abnormalities in the heartbeat that sound like valve problems, he or she will
probably use a more precise test to identify the exact cause of the noise.
