Pulmonary Atresia and Tricuspid Atresia

Pulmonary Atresia

​​Pulmonary atresia is a congenital heart defect present at birth in which the valve that lets blood out of the heart to enter the lungs (pulmonary valve) isn't formed correctly. Generally, instead of opening and closing to allow the passage of blood, a solid sheet of tissue forms disallowing blood from the right side of the heart to return to the lungs to become oxygenated. This is a life-threatening situation and procedures and medication need to be implemented immediately following birth.

Tricuspid Atresia

Similar to pulmonary atresia, tricuspid atresia happens when the tricuspid valve isn't formed correctly and is instead a solid piece of tissue between the right atrium and right ventricle. This results in a lack of oxygenated blood flowing through the heart and returning to the body. Babies with tricuspid atresia tire easily, are often short of breath and generally have blue-tinged skin. Surgery is performed shortly after birth to correct the deformity.
