Ebstein's anomaly is a rare heart defect that's present at birth (congenital). In Ebstein's anomaly, your tricuspid valve — the valve between the chambers on the right side of your heart — doesn't work properly. Blood leaks back through the valve, making your heart work less efficiently. Ebstein's anomaly may also lead to enlargement of the heart or heart failure.
bstein's anomaly is a heart defect that you have at birth (congenital). Why it occurs is still unknown. To understand how Ebstein's anomaly affects your heart, it helps to know a little about how the heart works to supply your body with blood.
Mild forms of Ebstein's anomaly may not cause symptoms until later in adulthood. If signs and symptoms are present, they may include:
Shortness of breath, especially with exertion, Fatigue, Heart palpitations or abnormal heart rhythms (arrhythmias), A bluish discoloration of the lips and skin caused by low oxygen (cyanosis)
Treatment of Ebstein's anomaly depends on the severity of the defect and your signs and symptoms. The goal of treatment is to reduce your symptoms and avoid future complications, such as heart failure and arrhythmias. Treatments may include:
If you have no signs or symptoms or abnormal heart rhythms, your doctor may recommend only careful monitoring of your heart condition with regular checkups. Checkups typically include a physical exam, electrocardiogram, chest X-ray, echocardiogram and, if necessary, a Holter monitor test. Your doctor may also ask you to undergo an exercise test, such as walking on a treadmill. This test checks your heart's response to physical activity.
If you have heart rhythm disturbances, medications may help control heart rate and maintain normal heart rhythm.
Your doctor may also prescribe medications for signs and symptoms of heart failure, if you need them. These may include drugs that prevent water retention (diuretics) and other medications.
