A heart murmur is an extra or abnormal sound that happens when the heart pumps blood. Your child's healthcare provider can hear the murmur when listening to your child's heart with a stethoscope. Heart murmurs are common in children, and are most often a normal part of their growth. At some point, just about every child will have a heart murmur. A heart murmur usually doesn't mean that your child has a serious health issue. But in rare cases, a heart murmur can be a sign of a serious condition. That's why it's important for your child to see a cardiologist. A cardiologist can find out if your child's murmur is caused by a problem in his or her heart, or if it's nothing to worry about.
Heart failure (CHF) is a condition in which the heart does not pump as well as it should. When this happens, fluid can build up in the lungs or body tissues (congestion). HF can cause lung problems, organ failure, and other serious problems in the body. Your child's healthcare provider will evaluate your child's heart and discuss treatment options with you.
