Tricuspid valve abnormalities are problems with the structure of
the heart valve that is located between the upper right and lower right
chambers. The tricuspid valve may not form correctly or not form at all during
Tricuspid valve abnormalities can interfere with normal blood flow.
A normal tricuspid valve keeps the blood flowing in one direction to the lungs.
Blood needs to take up oxygen from the lungs before the left side of the heart
sends it throughout the body.
Examples of tricuspid valve abnormalities include tricuspid atresia
and Ebstein's anomaly. Some babies who are born with an abnormal tricuspid
valve have other heart defects that help him or her to survive. These other
defects help the heart get oxygen-rich blood to body tissues.
