Ebstein anomaly is a rare heart defect in which the tricuspid valve — the valve between the upper right chamber right atrium and the lower right chamber right ventricle of the heart — isn't formed properly. As a result, blood leaks back through the valve and into the right atrium. Atrial septal defect is a hole between the two upper chambers of the heart. Ebstein anomaly is a rare heart defect that's present at birth congenital. In this condition, your tricuspid valve is in the wrong position and the valve's flaps leaflets are the incorrect shape.

Ebstein's anomaly is a malformation of the tricuspid valve. In this defect, there is a downward displacement of the tricuspid valve located between the upper and lower chambers on the right side of the heart into the right bottom chamber of the heart or right ventricle.

It is usually associated with an atrial septal defect. See a Stanford specialist to learn about your treatment options. Visit our clinic to make an appointment. Ebstein's Anomaly congenital heart defect ebsteins-anomaly. Adult Congenital Heart Program Causes Symptoms Diagnosis Treatments.

Ebstein's anomaly

Ebstein's anomaly is a congenital heart defect in which the septal and posterior leaflets of the tricuspid valve are displaced towards the apex of the right ventricle of the heart. The annulus of the valve is still in the normal position. The valve leaflets, however, are to a varying degree, attached to the walls and septum of the right ventricle. A subsequent "atrialization" of a portion of the morphologic right ventricle which is then contiguous with the right atrium is seen. This causes the right atrium to be large and the anatomic right ventricle to be small in size. While Ebstein's anomaly is defined as the congenital displacement of the tricuspid valve towards the apex of the right ventricle, it is often associated with other abnormalities. Typically, anatomic abnormalities of the tricuspid valve exist, with enlargement of the anterior leaflet of the valve.

There is no recognized gender predilection, and almost all cases seem to be sporadic, although an association with maternal lithium carbonate injection has been postulated 6. A few familial cases have been reported 6,7. In less severe cases, it may present at birth. Depending on the degree of atrial right-to-left shunting , the infant may or may not be cyanotic. The main abnormality is an abnormal tricuspid valve particularly septal and posterior leaflets , which is displaced apically into the right ventricle , resulting in atrialization of the parts of the ventricle above the valve. This results from the tricuspid valve leaflets inadequately separating from each other, or from the chorda tendinae from the inferior portion of the ventricle, during embryologic development. There can be concurrent tricuspid regurgitation with or without stenosis.
