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 prevents back flow of blood from the right ventricle into the right atrium during ventricular systole when the valve closes and allows blood to flow from right atrium into right ventricle during ventricular diastole when it opens.
