About

The Echocardiography Laboratory in the Labatt Family Heart Centre provides diagnostic cardiac ultrasound for children with suspected or known heart disease. We evaluate patients ranging from the fetus to childhood to adolescence. Using state-of-the-art equipment, ultrasounds are performed by highly skilled pediatric sonographers and interpreted by a world-class team of diagnostic physicians. We perform pediatric transthoracic echocardiograms (TTE), transesophageal echocardiograms (TEE), exercise stress echocardiograms, contrast echocardiograms, and fetal echocardiograms. 

Non-sedation echo is located on 4B in the Atrium (Cardiology clinic) and the sedation* Echo (for children under three years old) is located on the 4th floor Burton Wing (CDIU/PACU unit).  You will be told by telephone which area you must go to for your test.  

*Sedation is medicine to make your child sleepy or more comfortable during a hospital test or treatment. 

Non-sedation echocardiograms

A child lies on a hospital bed with chest sensors while an adult uses an ultrasound probe to scan the chest. A heart image appears on a medical monitor.
A nurse performs a non-sedation echo.

What to bring

  • Bring your child’s favorite blanket, toy, or stuffed animal to help them feel more comfortable during the exam.
  • Bring snacks or drinks to help distract them during the procedure.
  • Bring a bottle of milk for bottle-fed babies to use during the exam if needed.

Parents will be allowed to accompany their child into the exam room. It may be helpful to make other arrangements for siblings. Child Life specialists are available to help prepare and support your child during the scan. A Child Life specialist can be present at your child's appointment to explain the process to your child and help them adjust to the hospital experience.

After the test

There’s no downtime required after a non-sedation echo, so you can resume normal activities right away.

Types of non-sedation echocardiograms

There are no special preparations to follow: wear comfortable clothing, no special fasting required, also continue taking your regular medications unless your doctor tells you otherwise.

  • Your child should have breakfast on the day of the exercise test, and lunch for the appointments scheduled in the afternoon. The patient must have nothing to eat 1 hour prior to their appointment (juice and water is fine).
  • No caffeine products the day before and the day of the test.
  • Please refrain from using lotions/oils on your child’s skin the night before their appointment.
  • Your child should take their medication as usual, unless otherwise instructed by their physician.
  • Ensure you bring the following items: comfortable clothing and running shoes (shorts, loose fitting T-shirt)

No specific preparation for this scan.

A contrast agent (microbubbles) will be injected into a vein, usually in your arm. The microbubbles will then travel through your bloodstream and help improve the visibility of the heart structures on ultrasound images.

Sedation echocardiograms

  • A nurse will call you at home to determine if your child is a good candidate for sedation and discuss the sedation process with you.
  • Your child's stomach must be empty during and after sedation. If your child's stomach is not empty, your child could vomit while asleep and damage their lungs.
  • Follow the NPO Guidelines for important instructions on when to stop eating and drinking before sedation.
  • If you are driving to the appointment, please bring another adult with you to sit beside your child on the way home.
  • If your child takes prescription medicine, the nurse will discuss with you during preparation phone call when and how to give the medicine.

A nurse will give your child sedation

A nurse at the hospital will give your child sedation. The nurse will also watch your child closely while they are sedated.

There are different ways your child can get sedation

The nurse will decide and discuss with you which type of sedation is best for your child for the procedure:

  • as a drink
  • as a nasal spray

The nurse will watch your child closely during sedation

Before your child gets the sedation, the nurse will ask you and your child some important questions. They will do a physical exam to make sure that it is okay for your child to get sedation.

While your child is sedated, the nurse will monitor your child's blood pressure, heartbeat and breathing often. The nurse may use several different machines, called monitors, to check on your child.

After the sedation, the nurse will watch your child closely until they are ready to go home.

Sedation may cause minor side effects

Your child may have side effects after the sedation is given. Usually, these side effects are minor. They may include:

  • Dizziness or instability
  • Upset mood, feeling grumpy or tearful
  • Feeling sleepy

Sometimes, instead of making your child sleepy, sedation may make your child overly active and upset. If this happens, the nurse will stay with your child until they calm down, but the test or treatment may have to be arranged for another day.

The nurse will let you know when you can be with your child

For the sedation echo, you and a second adult will be allowed to be with your child. Once your child is asleep, only one person can be at the bedside as the nurses will need quick access to the emergency equipment if needed. Your child's nurse will let you know more about this.

Your child will be ready to go home when they are awake

Your child will be ready to go home when they are awake and able to drink clear fluids. This appointment may take one or two hours.

Taking your child home from the hospital

  • Bring another adult with you when you take your child home from the hospital.
  • If you are driving home, a second adult must be available to sit beside and watch your child in the car. Please make sure your child wears their seat belt.
  • If your child uses a stroller, bring it with you to the hospital. Your child may be dizzy and unable to walk on their own.
  • You will get written instructions from your nurse before leaving the hospital. These notes will tell you what you need to know once you are at home.

Echo images are interpreted on the same day and a report will be sent to your physician's office.

Research

We have an integrated Cardiovascular Ultrasound Research Program  which develops and explores the clinical utility of newer echocardiographic techniques for the diagnosis and management of paediatric cardiovascular disease. Established in 2005, we offer a unique environment for cardiovascular imaging research where researchers, engineers, and research sonographers collaborate to study vascular and cardiac function in children.

Fetal Cardiac Program

The Fetal Cardiac Program provides diagnosis, counseling, and treatment for potential heart problems in the developing baby during pregnancy.

An echocardiogram (or ‘echo’) is a special test that uses ultrasound (sound waves) to take pictures of the heart. Learn about how they are done, and how to help your child prepare for one.
