Pulmonary atresia is a heart defect present at birth (congenital) that's normally diagnosed within the first few hours or days of life. In pulmonary atresia, the valve that lets blood out of the heart to go to your baby's lungs doesn't form correctly. Instead of opening and closing to allow blood to travel from your heart to your lungs, a solid sheet of tissue forms. Blood from the right side of your baby's heart can't go back to the lungs to pick up oxygen.Pulmonary atresia may occur with or without a ventricular septal defect (VSD).
Bluish colored skin (cyanosis), Fast breathing, Fatigue, Poor eating habits (babies may get tired while nursing or sweat during feedings), Shortness of breath.The temporary measure, which has to be taken in new-borns with pulmonary atresia, is usually given an intravenous drug (injected into a vein) called prostaglandin E1 to prevent the ductus arteriosus from closing. Blood can flow from the right side of the heart to the left side and pass through the left ventricle to the lungs to pick up oxygen by keeping the ductus arteriosus open.
In Italy statistical analysis of pulmonary atresia were given result as there were 21 cases of pulmonary atresia. Eleven were diagnosed before 24 weeks and nine of them (82%) underwent termination of pregnancy. The survival rate was 50% among the 12 fetuses born at term. None of the fetuses that survived had a large right ventricle, while this was a finding in 50% of those that died. Among the fetuses that died, 83% had a hypertrophic right ventricular wall compared to 33% of the survivors. There were 12 cases of pulmonary stenosis. All the fetuses with pulmonary stenosis were born at term and four died in the perinatal period.
