The material used does not grow with the child so that the child could be larger tubes available. The tubes can be narrowed over time. If the tube does not have a valve in it, the blood is pumped out of the heart can leak backward, making the heart work harder than it should be. Patients with a form of congenital heart disease may require some form of open-heart surgery in which a tube is placed in this area to allow blood to pass freely into the lungs. Normal human heart has four valves that direct blood flow through the heart, ensuring that the blood travel in one direction. Many forms of congenital heart disease involving the pulmonary valve, which connects the heart to the blood vessels in the lungs.

Common symptoms of pulmonary valve stenosis in children include fatigue with exercise and swelling in the ankles and feet. To reduce the swelling, the doctor may prescribe a diuretic, a drug that causes an increase in passing urine. Usually, if one occurs, the child will need open heart surgery to replace the tube, usually with the larger tube has a valve in the works. Alternatively, some children may have a new valve placed using a long, flexible tube called a catheter, rather than through the more invasive open-heart surgery. Medications can help manage the symptoms caused by the leaky pulmonary valve.

But there is no specific drug proven to improve blood leaks from behind the pulmonary valve into the right ventricle pumping. Your doctor may recommend open-heart surgery to correct a heart valve leak when the heart is pumping chamber (right ventricle) become significantly enlarged due to work harder to manage excess blood received - from the second valve and the leaking of blood circulating throughout the body. Open heart surgery to replace a leaky valve lung and is usually very successful, with a low complication rate. Valves or other structures may also need improvement, and this is determined on an individual basis.
