Tricuspid Atresia | MedStar Health

Expert, lifelong care for a defect that blocks blood flow in the heart

Tricuspid atresia is a heart defect present at birth in which solid tissue forms between the right atrium and right ventricle instead of the valve that should be there. Babies with the disease need heart surgery within the first few years of life.

If you had tricuspid atresia when you were born, you’ll need lifelong care to monitor your heart health. Our Adult Congenital Heart Center specializes in caring for adults with these types of conditions.

What are the complications of tricuspid atresia?

If you were treated for tricuspid atresia as a child, you may get tired easily during exercise or other physical activities. You also may be at higher risk for developing a pulmonary embolism, or a blood clot that blocks an artery in the lungs, as well as an abnormal heartbeat.


Your doctor will need to check your heart on a regular basis to make sure you don’t need treatment for any additional conditions that may have developed.

Cardiac Catheterization

Cardiac catheterization is a minimally invasive way to diagnose and treat a variety of heart and vascular conditions by guiding thin, flexible tubes called catheters through blood vessels to problem areas.

Chest X-ray

Chest X-rays use a small dose of radiation to create pictures of the structures inside the chest, including the lungs, heart, and chest wall.

Computerized Tomography (CT) Scan

The cardiac computed tomography scan, or cardiac CT, uses X-rays to create three-dimensional images of your heart and blood vessels.


An echocardiogram uses high-frequency sound waves to create images of your heart.

Electrocardiogram (ECG)

An electrocardiogram, also known as an ECG, measures the heart’s electrical activity.

Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging, better known as cardiac MRI, is a combination of radio waves, magnets, and computer technology to create images of your heart and blood vessels.

Stress Tests

Stress tests are used to assess how your heart works during physical activity. There are several types of stress tests, including treadmill or bike stress tests, nuclear stress tests, stress echocardiograms, and chemically induced stress tests.

Transesophageal Echocardiogram (TEE)

Transesophageal echocardiogram allows us to take very detailed images of your heart structure from a probe in your esophagus.


If you develop another heart condition, your doctor may recommend treatment options specific to your needs. These treatments could include lifestyle modifications, medication, or more advanced options.

Congenital Heart Disease Treatments

Treatments for congenital heart conditions range from atrial septal defect and patent foramen ovale closures to cardiac ablations and heart valve replacements to heart transplants.

Structural Heart and Valve Disease Treatments

Structural heart and valve disease treatments address defects or abnormalities with the heart’s muscle or valves with or without surgery.

Tricuspid Valve Surgery

Tricuspid valve surgery includes repair or replacement of a damaged valve using traditional or minimally invasive methods.

Valve Disease Treatments

Valve disease treatments include monitoring, medication, or surgery to repair or replace a damaged valve.
