What is Pulmonary atresia

Pulmonary atresia is a congenital heart defect that affects the pulmonary valve, which is responsible for regulating blood flow from the heart to the lungs. In individuals with this condition, the pulmonary valve is either missing or abnormally developed, obstructing the blood flow to the lungs.

As a result, the right ventricle, the chamber of the heart that pumps blood to the lungs, may also be underdeveloped or have abnormalities. This can lead to inadequate oxygenation of the blood and cause symptoms such as cyanosis (bluish discoloration of the skin), difficulty breathing, fatigue, and poor weight gain.

Treatment for pulmonary atresia depends on the severity of the condition and may involve surgical interventions to improve blood flow to the lungs. These procedures can include creating a connection between the heart and lungs using a shunt, enlarging or reconstructing the pulmonary valve, or performing a heart bypass.

Regular medical follow-up is necessary for individuals with pulmonary atresia to monitor their heart function and address any potential complications. With appropriate medical care, many individuals with this condition can lead fulfilling lives.
