Answer 2

Answer:

When things go wrong

In tricuspid atresia, the right side of the heart can't pump enough blood to the lungs because the tricuspid valve is missing. A sheet of tissue blocks the flow of blood from the right atrium to the right ventricle. As a result, the right ventricle is usually small and underdeveloped (hypoplastic).
