Ebstein's Anomaly

Diagnosis

Mayo Clinic doctors trained in heart diseases (cardiologists) work with other specialists to accurately evaluate and manage Ebstein's anomaly and other congenital heart diseases.

Tests to diagnose Ebstein's anomaly may include:

• Cardiac catheterization. In this test, your doctor inserts a long, thin tube (catheter) into an artery in your groin and guides the catheter to your heart using X-ray imaging. Your doctor injects a special dye into an artery in the heart, making the arteries visible under X-ray. This test shows how your heart is functioning. During catheterization, your doctor may conduct tests to check your heart's electrical system for heart rhythm problems.
• Chest X-ray. Your doctor may order a chest X-ray to look for heart enlargement.
• Echocardiogram. During an echocardiogram, sound waves create detailed images of your heart. This test assesses the structure of your heart and blood flow through your heart. Doctors will usually diagnose you with Ebstein's anomaly using an echocardiogram (ultrasound of the heart).
• Electrocardiogram (ECG). In an electrocardiogram, sensor patches with wires attached (electrodes) measure the electrical impulses given off by your heart. An ECG shows enlargement of the upper right heart chamber (atria) and detects any abnormal heart rhythm.
• Stress test. This test assesses your heart rate, blood pressure, and tissue oxygenation at rest and at various level of exercise. This test allows your doctor to accurately assess how your heart condition such as Ebstein's anomaly is affecting you and helps in timing of surgery if needed.
