Conditions and Treatments

From the beginning of care, through treatment, and into recovery, we provide an experience that’s right for children and families. Children’s National Heart Institute provides a wide range of clinical services and specialties dedicated to improving children's cardiac health.

Aortic Coarctation

Coarctation of the aorta (COA) is a congenital (present at birth) heart defect involving a narrowing of the aorta.

Aortic Stenosis

Aortic stenosis is a heart defect that causes problems with the aortic valve that make it harder for the leaflets to open and permit blood to flow forward from the left ventricle to the aorta. Learn more about this condition.

Arrhythmia

An arrhythmia is an abnormal heart rhythm. Learn more about this condition.

Atrial Septal Defect (ASD)

An atrial septal defect is an opening in the atrial septum, or dividing wall between the two upper chambers of the heart, known as the right and left atria. Learn more about this condition.

Atrial Septal Defect (ASD) Closure Devices

Our heart specialists offer expert treatment for atrial septal defect (ASD) closure, including Amplatzer® and Gore® Helex® Septal Occluders. Learn more about these treatments.

Atrioventricular Canal (AV canal or AVC)

Atrioventricular canal defect (AV canal) is a congenital (present at birth) heart defect. Other terms used to describe this defect are endocardial cushion defect and atrioventricular septal defect (AVSD).

Cardiac Ablation

Our expert pediatric electrophysiology specialists have years of experience performing cardiac ablation procedures for children.

Cardiac Catheterization

Cardiac catheterization is a specialized procedure in which a long, flexible tube (catheter) is inserted into a blood vessel (usually in the leg) and guided into the heart, allowing a close look at the structures inside.

Cardiac First Trimester Imaging

With new ultrasound equipment that has very high resolution and techniques such as transvaginal ultrasound, the heart may be imaged as early as 11-12 weeks gestation.

Cardiac Imaging

Children's is a national leader in congenital heart disease imaging. The pediatric echocardiography laboratory performs approximately 14,000 studies annually.
