Cardiac Catheterization

Our team of cardiac interventionists performs more than 600 procedures annually.

Learn more about our Cardiac Catheterization Lab.

Cardiac Imaging

We offer advanced imaging techniques to obtain highly detailed pictures of your child’s heart structure and function:

  • Echocardiography: This is an ultrasound of the heart. We perform more than 20,000 echocardiograms per year, including nearly 3,000 fetal echocardiograms, making us one of the busiest echocardiography laboratories in the country. 
  • Cardiac MRI: A noninvasive imaging technique, cardiac MRI provides comprehensive evaluations for complex heart conditions, such as tetralogy of Fallot and cardiomyopathies
  • Interventional Cardiac MRI: This unique program allows us to perform MRI procedures and cardiac catheterization procedures on the same day, reducing the need for sedation and multiple procedures. 


Our expert pediatric electrophysiologists provide comprehensive heart rhythm management of arrhythmias and syncope in children. We offer the latest and safest technologies, including cryoablation therapy, and 3-D mapping without X-ray radiation. Learn more about our Electrophysiology Program.

Kawasaki Disease Program

Our program, led by an internationally recognized Kawasaki disease expert treats children who are newly diagnosed with Kawasaki disease as well as children who have developed coronary artery aneurysms as a result of having Kawasaki disease. Learn more about the Kawasaki Disease Program.

Prenatal Cardiology Program

Through this innovative program, the unborn child is cared for as a separate and individual patient. Comprehensive care begins in utero and is coordinated in partnership with referring maternal prenatal pediatrics specialists and obstetricians with many subspecialties, including cardiology, cardiac surgery, genetics, and radiology. A unique feature of the program is while our team cares for the prenatal heart, we monitor brain function and other aspects of prenatal development to ensure the best outcomes. Learn more about the Prenatal Cardiology Program.

Preventive Cardiology Program 

This multidisciplinary program (the combination of different specialists) is working to improve the diets and lifestyles of our patients to reduce the risk of cardiovascular disease. These risk factors include abnormal cholesterol, hypertension, increased weight, and other adverse lifestyle choices, such as lack of exercise and tobacco use.

Washington Adult Congenital Heart Program

In order to ensure that our patients have appropriate heart care as adults, we established the Washington Adult Congenital Heart (WACH) Program, a collaborative care partnership with MedStar Washington Hospital Center. Our program is 1 of only 40 Adult Congenital Heart Association (ACHA)-accredited programs in 25 states.
