Ebstein's anomaly
Ebstein's anomaly is a condition in which the valve between your right heart chambers (tricuspid valve) is malformed and sits lower than normal in the lower-right heart chamber (right ventricle). This condition is associated with right ventricle dysfunction, and commonly a hole in the upper chambers of the heart (atrial septal defect or patent foramen ovale). Because the tricuspid valve is malformed, it doesn't function properly. As a result, blood may leak backwards into the right atrium, leading to enlargement of the right heart chambers. The heart chambers weaken as they enlarge, leading to irregular heartbeats, fatigue, and possibly heart failure and stroke.
Ebstein's anomaly occurs in less than 1 percent of people who have congenital heart disease. Many people who have Ebstein's anomaly also have a hole in the heart (atrial septal defect or patent foramen ovale) or have irregular heart rhythms (Wolff-Parkinson-White syndrome or atrial fibrillation).
Mayo Clinic doctors with training in heart disease (cardiologists) treat people who have Ebstein's anomaly. Many cardiologists have experience in treating congenital heart disease (congenital cardiologists). Mayo Clinic doctors have treated thousands of people who have congenital heart diseases for more than 60 years. Cardiologists, surgeons and other specialists in the Center for Congenital Heart Disease work closely to care for you.
