A heart murmur isn’t always serious. However, if your child’s heartbeat sounds unusual, it’s important to see a cardiologist to be sure. If your child does need treatment at all, the specialists at Children’s Health can help. Physicians at Children’s Health are world-class subspecialists from UT Southwestern with years of experience caring for children with heart murmurs.
Heart murmurs are extra or unusual sounds made by blood circulating through the heart or nearby blood vessels. In many cases murmurs are not serious and do not affect a child’s health, but they can be part of a more serious condition.
Many times, what sounds like a murmur is actually the sound of blood moving through the heart normally. Also known as “innocent murmurs,” these sounds come and go, such as when a child has a cold or the flu.
Heart murmurs become more worrisome when a child also has structural heart problems or certain infections known to cause heart damage, such as endocarditis and Rheumatic fever. In these cases, an abnormal heart murmur is often the first noticeable symptom of a more serious heart condition.
If your child has innocent heart murmurs, he or she will not experience any symptoms. The extra sounds may come and go, but your child will eventually outgrow them.
Abnormal heart murmurs also have no symptoms other than unusual sounds your doctor hears when listening to your heart. When children with an abnormal heart murmur start showing other symptoms, it’s time to see a cardiologist.
An abnormal murmur itself is not a disease. More importantly, it’s a sign that your child may need additional tests to diagnose the condition that may be causing it. We start with a comprehensive exam, which may include one or more diagnostic tests.
Sometimes a heart murmur is a sign that your child has a congenital heart defect.
