What is Tricuspid Atresia?

In the heart, the tricuspid valve is the passageway that controls the flow of blood between the right atrium (where the blood enters the heart) and the right ventricle (where the blood leaves for the lungs). Tricuspid atresia is a problem with this valve that blocks the flow of blood. The result is that the body receives blood with less oxygen than it needs.

Tricuspid atresia is a defect that babies are born with (congenital birth defect). It is often present with other heart problems. The exact cause is not known.

Babies with tricuspid atresia will be extremely fatigued, have rapid breathing, exhibit poor feeding and growth and have a bluish color due to lack of oxygen.
