Pulmonary Atresia

  • Pulmonary atresia

    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).

  • Pulmonary atresia

     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.

  • Pulmonary atresia

     In Hong Kong the statistical analysis of pulmonary atresia got result as seven patients died before interventions. Of the remaining 87 patients who underwent intervention at a median age of 9 days (from 1 day to 2 years), 12 had right ventricular outflow tract reconstruction (RVOTR), 42 had closed pulmonary valvotomy (CPV), and 15 had laser assisted valvotomy with balloon valvoplasty. A systemic-pulmonary shunt was inserted in 18 patients, six of whom had subsequent RVOTR (n = 4) or laser assisted valvotomy (n = 2). Since 1990, catheter intervention accounted for 38% (17 of 45) of the right ventricular outflow procedures.
