Tricuspid Atresia Repair

Tricuspid Atresia Repair

Tricuspid atresia is a heart condition at birth. The tricuspid heart valve is missing or not developed properly. The condition obstructs blood flow from the right atrium to the right ventricle.

Children with tricuspid atresia usually require two or three surgeries to reroute blood flow so it is balanced between the lungs and body. The timing of the first surgery depends on the balance of blood from the lungs to the body. The baby will be evaluated after birth to determine what is required. If the blood flow is balanced, surgery can be delayed and possibly only two surgeries may be needed.

Some children need more blood going to their lungs. These children need a tube-shaped conduit, called a shunt, to carry more blood to the lungs. This tube is called a Blalock-Taussig (BT) shunt. If too much blood is going to the lungs, some children will require a pulmonary artery band (PAB) limiting the blood flow to the lungs.

As the child gets older, they will need to have a Bidirectional Glenn Procedure and a Fontan Procedure.
