Tricuspid Atresia is a congenital heart defect in which the tricuspid valve does not form, preventing normal blood flow from the right atrium to the right ventricle. The right ventricle is often underdeveloped, and babies usually have an opening between the atria, such as an atrial septal defect, to allow blood to reach the left side of the heart. Other defects, including a ventricular septal defect or patent ductus arteriosus, may also help maintain blood flow to the lungs; symptoms and treatment depend on the amount of pulmonary blood flow and associated heart abnormalities.
Timely diagnosis and treatment are essential because tricuspid atresia can cause low oxygen levels, inadequate blood flow to the lungs, or excessive pulmonary blood flow that may damage the lung blood vessels. Early treatment helps support oxygen delivery, maintain appropriate blood flow, and reduce the risk of serious complications. Lifelong follow-up with a congenital heart specialist is necessary because complications may develop even after successful surgical treatment.
Causes
Risk Factors
Ductal Stenting: In selected babies, a stent may be placed in the ductus arteriosus to maintain pulmonary blood flow and reduce the need for an early surgical shunt.
Systemic-to-Pulmonary Artery Shunt: A surgical shunt may be created to increase blood flow to the lungs when the baby's anatomy requires additional pulmonary blood flow.
Balloon Atrial Septostomy (BAS) : A cardiologist performs a BAS (also known as a Rashkind procedure). They insert a thin, flexible tube called a catheter into a blood vessel, usually in the groin, and thread it up to the heart.

Pulmonary Artery Banding: If too much blood is reaching the lungs, pulmonary artery banding may be used in selected patients to control pulmonary blood flow and protect the pulmonary circulation.
Bidirectional Glenn Operation : In this staged procedure, the superior vena cava is connected directly to the pulmonary arteries, allowing blood from the upper body to flow to the lungs without passing through the right ventricle.
Fontan Procedure : The final major stage of palliation connects venous blood from the lower body to the pulmonary arteries, allowing blood to reach the lungs without ventricular pumping. Selected patients may undergo a fenestration.
Heart Transplantation : Rarely, transplantation may be considered when the heart becomes severely weakened or when the Fontan circulation fails, and other treatments are unsuitable.
