Tricuspid atresia is a congenital problem of the tricuspid valve, the inflow valve to the right ventricle.
With this valve issue the right ventricle doesn't usually form normally.
In the first week of life it will be established if the lungs are getting an appropriate amount of flow. Kids usually have 2 or 3 surgeries to in the first four years of life.
Surgeries include the glenn and fontan.
