Medical Therapy
- Medical therapy in newborns with Pulmonary atresia serves only as a bridge to surgical treatment. It is temporarily and definitive treatment is only surgical.
- It is targeted to keep the ductus arteriosus open that otherwise will close in 48 hr. An IV medication called prostaglandin E1 is used to keep the ductus arteriosus open and gives time while the newborn will be prepared for the definitive treatment. Blood circulates from the aorta to the pulmonary artery via this ductus and gets oxygenated in the lungs.
- Another short term strategy is keeping the opening between the right and left atrium patent ( foramen ovale ). This process is called "Balloon atrial septostomy" done via Cardiac Catheterization. A guided wire with the tip of the balloon on it is inserted via vein and advanced to the right side of the heart. reaching the foramen ovale. The balloon tip is inflated and adjusted at the opening and the wire is removed This opening will shunt the blood from the right atrium to the left, to the aorta, and via ductus arterosus to the pulmonary artery and then to the lungs for proper oxygenation.
- It should be kept in mind these procedures ONLY are the short term management and eventually newborn will need surgery. [1] [2] [3]
