Tricuspid Atresia

Tricuspid atresia is a rare heart defect where the tricuspid valve, which controls blood flow in the heart, doesn't form at all. This causes problems with blood flow from the right atrium to the right ventricle and out to the lungs. Babies born with tricuspid atresia may need surgery or other procedures soon after birth to help with blood flow. It's important for people with this condition to have regular checkups with a heart doctor to stay as healthy as possible.
