Overview

Tricuspid atresia is defined as a congenital heart defect whereby there is a complete absence of the tricuspid valve. Therefore, there is an absence of right atrioventricular connection. This leads to a hypoplastic (undersized) or absent right ventricle. Irrespective of the gender, it occurs equally both in boys and girls. In a normal condition, the tricuspid valve is positioned on the right side of the heart, whereas in the babies affected with this disease, there is no tricuspid valve at all, and the right ventricle is small. The filtering away of blue blood is not any big problem until the baby with tricuspid atresia is inside the mother’s womb. The baby will find way to pass oxygen to the lungs, provided by the mother. But once the baby is born, the levels of oxygen are lower than usual, and the fingernails and lips of the baby begin to turn blue. It becomes quite difficult for the baby to create a pathway to carry oxygen to the lungs. The disease occurs in quite rare cases, affecting 3-5 in some 20,000 births.
