Cardiac catheterization

Cardiologists at Norton Children’s Heart Institute use cardiac (heart) catheterizations to give them more information about the heart, produce videos of the  blood flow through and away from the heart and to perform other procedures to fix heart conditions and defects.

The catheter is a long, thin tube that the cardiologist inserts into the body through a vein or artery.Most commonly, this is done through a small cut in the skin close to the groin, but sometimes other large vessels are used including veins in the neck.

During a cardiac catheterization:

  • Your child may need to be sedated (asleep) for some procedures. A specially trained pediatric cardiac anesthesiologist will administer the general anesthesia .
  • The cardiologist then threads a small, long, flexible tube (catheter) through a blood vessel until it reaches the heart and major vessels around the heart.
  • The cardiologist may inject X-ray dye through the catheter to help them see the structures in and around the heart more clearly. This can help them find and diagnose heart defects as well as heart function.
  • The cardiologist can take pressure measurements and get blood samples from the different chambers and blood vessels around the heart. These readings give detailed information about how your child’s heart is working.
  • Sometimes, the cardiologist can find and diagnose heart conditions during the catheterization and treat it right away.
  • A heart catheterization usually takes two to five hours to complete.
  • Recovery time can vary from six hours to an overnight stay. You and your child should come to the hospital prepared to stay overnight.
  • Why have a cardiac catheterization?

Cardiac catheterization can be used to diagnose heart conditions in children and provide more information if known heart conditions exist. During a catheterization, cardiologists can:

  • Measure blood pressure and oxygen levels in the heart and lungs
  • See how well the heart pumps
  • Take pictures of the heart
  • View the heart’s structure
  • View the heart’s electrical system

Cardiac catheterization complications and follow-up care

After the procedure, your child will be taken to a recovery room for observation. Depending on your child’s condition, observation may take a couple of hours or longer. Your child’s care team will talk with you about specific after-care instructions.

These procedures generally are low risk. Minor complications happen in fewer than 5 percent of all cases. Each type of heart catheterization procedure has its own unique risks and complications. You will be able to ask the cardiologist performing the procedure questions about your upcoming catheterization.
