OutlookA heart murmur isn't a disease, and most murmurs are harmless. Innocent murmurs don't cause symptoms. Having one doesn't require you to limit your physical activity or do anything else special. Although you may have an innocent murmur throughout your life, you won't need treatment for it.
The outlook and treatment for abnormal heart murmurs depend on the type and severity of the heart problem causing them.
