Heart Murmur

It is not unheard for children to be born with heart murmurs. In most cases, these murmurs cause no ill-effects and resolve on their own. To ensure your child’s health, doctors can perform in-depth testing and exams if they believe the issue stems from a more serious medical condition or cause.

What Are Heart Murmurs?

The heart has four chambers, and each chamber has a valve to ensure blood flows in the proper direction. Heartbeats occur as the valves close, but heart murmurs are caused by something else. Causes can include:

  • Narrowing or leakage of the valves
  • Malformed openings between the chambers
  • Problems with major blood vessels and their connection to the heart
  • Abnormal valve function

In the event of heart murmurs in a newborn, doctors will evaluate the child to determine if there is an underlying cause.

 

Are Heart Murmurs Always Dangerous?

Harmless heart murmurs are quite common in newborns. When detected, medical staff will consider the following:

  • The intensity of the heart murmur
  • How high- or low-pitched it is
  • The location of the murmur
  • Where it can be heard (i.e., the sides and back of the chest)
  • When the murmur happens (as compared to the first and second heartbeats)

Harmless heart murmurs often resolve as the baby’s heart grows and develops.

 

When Are Heart Murmurs Cause for Concern?

On their own, heart murmurs do not cause any major health problems. If your child has a heart murmur that is accompanied by one or more of the following, it could signal a more serious underlying issue:

  • Poor growth and development
  • Abnormal features
  • Existing circulatory issues

Doctors can also assign grades to heart murmurs, which range from 1 to 6 and indicate the loudness of the murmur.

 

What to Do If You are Concerned About a Childhood Heart Murmur

It is important for parents to monitor their child closely if they exhibit other physical effects. A problematic heart murmur can also cause the following symptoms:

  • Problems breathing
  • Recurring chest infections
  • Sweating while feeding
  • Bluish tint to the lips and skin

If any of these signs are evident in a baby or child, schedule an appointment with a pediatrician immediately or seek emergency medical attention if the child appears to be in serious distress.
