Tricuspid atresia is a heart defect present at birth (congenital) in which one of the valves (tricuspid valve) between two of the heart's chambers â the upper right chamber (right atrium) and the lower right chamber (right ventricle) â isn't formed.
The tricuspid valve allows blood to flow from the right atrium to the right ventricle, and prevents backflow. The two semilunar valves allow blood to flow from the ventricles, either into the pulmonary arteries from the right side, or into the aorta from the left side, and prevent backflow.
