Tricuspid Valve Abnormalities 

• Structural problem with 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.
• This can interfere with keeping 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: tricuspid atresia and Ebsten’s anomally.
• Sometimes the baby can stay alive by having other defects that get some oxygenated blood to the body tissues.
