A heart murmur is an extra or unusual sound heard during a heartbeat.
Treatment: Innocent murmurs do not need treatment. Treatment of other types of murmurs depends on your symptoms; the risk of heart damage over time if the abnormality is not corrected; and the risk of sudden complications, such as stroke or cardiac arrest. Treatment also depends on the cause of the murmur. If the murmur is caused by high blood pressure, you may be given medicines; if it is caused by a valve problem, you may need surgery.
