Tricuspid Valve Abnormalities
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 fetal growth.
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.
