Pulmonary atresia
Pulmonary atresia is a congenital birth defect of the pulmonary valve in which the valve does not develop. The valve is completely closed making it harder for blood to travel from the heart to the lungs.
The pulmonary valve is located on the right side of the heart between the right ventricle and pulmonary artery. In a normal functioning heart, the opening to the pulmonary valve has three flaps that open and close; however with this defect some of the flaps are not formed.[1]
The symptoms/signs of pulmonary atresia that will happen in babies would include fatigue and some shortness of breath.[2]
Pulmonary atresia can be fatal if no emergency surgery is done. If surgery is done, most children affected by this can live normal lives although problems such as strokes, heart disease and seizures are possible.[3]
