What a Pediatric Echocardiogram Can Catch That a Routine Checkup Might Miss

Your child's pediatrician listens to their heart during their regular wellness checks. If the doctor says that everything sounds normal, you probably feel reassured, but what does it mean if your child starts mentioning occasional chest discomfort or you notice they get unusually tired during physical activity?

The reality is that a stethoscope examination — while valuable — can sometimes miss heart problems. And if you or your child’s pediatrician suspects a heart condition, an echocardiogram can detect conditions that routine checkups completely miss.

Devyani Chowdhury, MD, MHA, and our team at Cardiology Care for Children in Gordonville, Lancaster, and Mifflinburg, Pennsylvania, and Shipshewana, Indiana, specialize in pediatric echocardiograms, which provide a detailed picture of your child's heart structure and function that a basic exam simply can’t provide. Here’s what you should know.

What to expect at a routine wellness checkup

Most children need to go to the doctor at least once a year for a wellness check. During your child’s physical exam, the pediatrician uses a stethoscope to listen to their heart. They're listening for obvious abnormalities like loud murmurs, irregular rhythms, or other gross abnormalities.

A normal checkup can identify some heart problems, particularly those causing significant murmurs or obvious symptoms. However, many heart conditions produce no audible murmur, irregular murmurs, or subtle murmurs that are easy to miss.

That means some conditions don't cause obvious symptoms that are noticeable during a routine checkup. A child might have normal vital signs, normal oxygen levels, and normal appearance, but still have heart issues that could benefit from additional testing and more specialized care.

How pediatric echocardiograms work

An echocardiogram, or echo, is a noninvasive heart test that uses ultrasound to visualize your child's heart in detail. Sound waves create detailed images of the heart's structure and function without radiation, and it’s the same safe ultrasound technology used in pregnancy.

During the test, your child lies on an exam table while our technician applies ultrasound gel and moves a probe across their chest. The probe sends sound waves that bounce off their heart's structures, creating real-time images displayed on a monitor. The entire test typically takes 20-30 minutes and is completely painless.

When your child might need an echocardiogram

Your pediatrician might recommend an echo if your child has a heart murmur, even if it's thought to be innocent. Any symptoms like chest pain, unusual shortness of breath, or excessive fatigue during normal activities warrant echo evaluation, too.

An echocardiogram might be appropriate if your child has a family history of heart disease or congenital heart conditions. Children with known heart conditions often need periodic echocardiograms to monitor how their condition is progressing and how treatment is working.

What a pediatric echocardiogram can detect

An echo visualizes the chambers of your child's heart, including the right and left atria and ventricles. It shows how thick the heart walls are and whether they're functioning properly. It displays all four heart valves and how well they're opening and closing. It measures blood flow through the heart and identifies any abnormal flow patterns.

Because it’s a visual test, an echocardiogram can catch problems that stethoscopes simply can’t detect. Structural abnormalities like septal defects (holes between chambers), valve abnormalities, and chamber enlargement become immediately visible. Functional problems like reduced heart pumping strength or abnormal blood flow patterns can also be identified.

An echocardiogram is one of the best ways to identify congenital heart disease that might have subtle or no murmur. We also use it to detect cardiomyopathy, pericardial fluid accumulation or inflammation, rhythm abnormalities, and valve problems that might not yet be causing symptoms.

Many heart conditions in children are manageable or treatable when caught early. Some require monitoring but no treatment, some need medication or intervention, and some resolve on their own. The key is knowing what you're dealing with so you can make informed decisions about your child's care and activity level.

If you or your child’s pediatrician have concerns about their heart health, an echocardiogram can help provide definitive answers. Contact Cardiology Care for Children online or call us at 717-925-8300 to discuss whether an echocardiogram could provide the detailed heart evaluation your child needs.
