Heart Murmurs in Children: Is Every Sound in the Heart Dangerous

Many parents feel anxious when a doctor tells them that their child has a heart murmur, especially because they often associate the term with serious heart disease. However, the truth is that not all heart murmurs are dangerous — in fact, many are completely normal sounds that occur as blood flows through the heart.

In this article, the expert team at Alexandria Pediatric Center explains everything you need to know about heart murmurs in children: their types, causes, and how to manage them safely and professionally.

 What Is a Heart Murmur?

A heart murmur is an unusual sound heard during a heartbeat, typically detected using a stethoscope. These sounds occur when blood flows through the heart or nearby vessels in a way that causes turbulence or an audible swishing sound.

 What’s the Difference Between Innocent and Pathological Murmurs?

1. Innocent (Harmless) Murmurs:

• Very common in children, especially in early childhood.

• Not linked to any structural problem or heart disease.

• Often disappear with age.

• Require no treatment or surgery.

2. Pathological Murmurs:

• Caused by congenital defects or issues in the heart valves or blood flow.

• May indicate a heart defect such as a hole in the heart or valve abnormalities.

• Require careful diagnosis and possibly medical or surgical intervention.

 When Is a Heart Murmur a Warning Sign?

Doctors at Alexandria Pediatric Center assess murmurs thoroughly, considering the following:

• Presence of accompanying symptoms, such as:

  • Difficulty breathing

  • Bluish lips or fingertips

  • Delayed growth or weight gain

  • Fatigue during feeding or activity

• Family history of heart conditions

• The sound’s characteristics and intensity

 How Are Heart Murmurs Diagnosed?

Diagnosis usually involves several steps, all available at the Pediatric Cardiology and Echocardiography Unit at Alexandria Pediatric Center:

1. Comprehensive physical examination with a stethoscope

2. Electrocardiogram (ECG) to assess heart rhythm

3. Chest X-ray

4. Echocardiogram (ultrasound of the heart) to evaluate valves, chambers, and blood flow

5. In some cases, cardiac MRI or catheterization may be needed

 Do All Murmurs Require Treatment?

• Innocent murmurs do not require any treatment, just periodic follow-up.

• Pathological murmurs are treated based on the underlying condition, and treatment may include:

  • Medications to support heart function

  • Regular monitoring

  • Surgery or cardiac catheterization for congenital defects
