How is an atrioventricular canal defect diagnosed?

A healthcare provider can often diagnose an atrioventricular canal defect before birth with a few tests:

  • Prenatal ultrasound shows moving pictures of the fetus in the uterus, including its heart. A large septal defect may be visible on an ultrasound.
  • A fetal echocardiogram creates images of the heart that are more detailed than ultrasound. It can give a healthcare provider important information about the structure of the heart and how well it’s pumping blood.

After birth, a healthcare provider may use a stethoscope to listen to your baby’s heartbeat. An abnormal “whooshing” sound may indicate that blood is flowing through a hole in the septum. Other tests after birth might include:

  • Chest X-rays to show the size and shape of your baby’s heart.
  • Electrocardiogram (EKG) to track the electrical activity of your baby’s heart.

In some cases, a baby may have a small septal defect that doesn’t cause symptoms right after birth. It might be several years before a healthcare provider detects the condition.
