Ventricular Septal Defect: After Your Child's Visit

Your Care Instructions

Picture of a normal heart and a heart with ventricular septal defect
The heart is a muscular pump that has four chambers. A ventricular septal defect is an opening in the wall between the lower chambers of the heart. It is a type of congenital heart defect, which means that your child was born with it.

When this defect is present, some of the blood may flow from one side of the heart through the opening to the other side. This can make the heart pump too much blood to the lungs and not enough to the rest of the body.

A very small opening may not cause problems. Small openings sometimes close on their own.

Larger openings can weaken the heart and lead to heart failure. Your doctor will determine if the opening should be closed with surgery.

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.

How can you care for your child at home?

  • Give your baby medicines exactly as prescribed. Call your doctor if you think your baby is having a problem with a medicine.
  • Help your baby eat well. This can be hard for some babies who have a heart defect. They may get tired when eating, so they may eat less and may not get enough calories.
    • Note your baby's first signs of hunger, such as fidgeting and sucking on a fist. Your baby will have more energy to eat well if he or she is not tired from crying.
    • Try to use a soft, special nipple made for babies born early. These nipples make it easier for your baby to get enough formula or breast milk if you bottle-feed.
    • Burp your baby a lot, especially when using a bottle. Babies who have trouble sucking take in large amounts of air when they eat. This can make them feel full before they get enough formula or breast milk.

When should you call for help?

Call 911 anytime you think your baby may need emergency care. For example, call if:

  • Your baby passes out (loses consciousness).

Call your doctor now or seek immediate medical care if:

  • Your baby has new or worse trouble breathing.
  • Your baby has a fever.

Watch closely for changes in your baby's health, and be sure to contact your doctor if:

  • Your baby has less energy or seems to be sleeping more than usual.
  • Your baby is not eating well.
  • Your baby does not get better as expected.
