By Mayo Clinic staffWhile there's not much you can do to prevent or treat a heart murmur, it is reassuring to know that heart murmurs are not a disease and are often harmless. For children, many murmurs go away on their own as they grow. For adults, murmurs may disappear as the underlying condition causing them improves.
If your heart murmur is cause for concern, the condition causing the murmur is often treatable. Your doctor or cardiologist can help you decide the best course of treatment to correct the problem.
