Symptoms of Mitral Valve Abnormalities

Mitral valve abnormalities may cause no symptoms for many years.

Your child may have some of these symptoms, depending on the valve problem and how severe it is:

  • Feeling short of breath when active or lying down
  • Coughing
  • Feeling more tired than normal
  • Having palpitations  
  • Having an arrhythmia  
  • Fainting or feeling dizzy
  • Having chest pain

Mitral Valve Abnormalities Diagnosis

To diagnose a problem with the mitral valve, your doctor will examine your child. The doctor will use a stethoscope to listen for abnormal sounds in their heart (a murmur) or the sound of a valve not closing well. Sometimes doctors find valve problems after hearing a heart murmur in a child who appears well.

Your child will need an echocardiogram test so the doctor can see how their heart is working

They may need other tests that provide more information about their heart. These include chest X-rays or MRI (magnetic resonance imaging) of the heart, cardiac catheterization, electrocardiogram and exercise testing.
