Ebstein’s anomaly is a rare heart defect. In a normal heart, the blood flows in from the body to the right atrium. It then goes into the right ventricle. Next, the blood travels to the lungs through the pulmonary valve. Here, it picks up fresh oxygen. The blood returns to the left atrium and goes into the left ventricle. The blood moves out to the rest of the body.
This defect occurs when the tricuspid valve develops lower than normal in the right ventricle. Also, the valve does not open and close normally. This allows blood to leak in the wrong direction. Ebstein’s anomaly can be mild to severe.
Ebstein's anomaly is present at birth. It is not known exactly why the heart does not develop normally.
Specific risk factors for Ebstein’s anomaly are not clear. 2 possible risk factors include:
