What is lung stenosis?
The pulmonary valve is attached to the right chamber of the heart. It is a passage through which blood flows to get into the lungs for oxygenation. Pulmonary stenosis, congenital heart defect, is to narrow the leaflets of this valve or the valve itself. Leaflets open when the right chamber pulls and pushes blood into the lungs, but when they are stenotic, the leaflets can stick or remain partially closed. Pulmonary stenosis is the most common of the flap defects. Peripheral pulmonary stenosis narrows the valve itself, but is generally mild. Such mild cases usually never require treatment, although doctors can hear the murmur of the heart when a stethoscope is applied to the newborn's chest. Risk with more serious forms of lung stenosis is to back up the fluid to the heart and vein and the need for the right ventricle to draw harder to shift blood into the lungs. Moreover, over time, the work that the heart can do lead to heart failure.
The most common intervention for the treatment of pulmonary stenosis is non -surgical. During cardiac catheterization is a small balloon attached to the catheter throughDrived by heart to the lung valve and then inflated to reduce the narrowing. This treatment, balloon valvuloplastics, has a high degree of success. It also has the advantage that the outpatient procedure is when it is successful.
Sometimes balloon valvuloplastics is not enough. The procedure may try to solve lung stenosis, but may not be successful. If there is still lung stenosis, several surgical options are available. The most common option is to consume the valve and replace it with either a pig valve or by a human corpse valve. Unlike other transplants, rejection in thi factories is not a surgery.
Children with this type of surgery are generally very good, but the valve does not grow with them, so at some point it is necessary to replace the valve. For most children, this can be done about ten years after the initial valve placement. The replacement of the valve, although it sounds serious, is usually cardIotoracal surgeons considered a relatively routine procedure.
survival is excellent for valve replacement. Due to the artificial valve, cardiologists recommend antibiotics before dental procedures. In addition, the child can be placed on long -term aspirin to prevent the formation of clots in the new valve. The child will have to see a cardiologist annually. This doctor will assess to what extent the new valve works, and also determines when the valve may require replacement.
A child with pulmonary stenosis rarely needs immediate intervention immediately after birth. Pulmonary stenosis affects the heart over time and changes the effect according to the degree of stenosis. Often, however, lung stenosis with other defects is present, as in Fallot tetralogy or the hypoplastic true heart of the syndrome . In these cases, surgery may need to be performed shortly after birth to resolve these further defects.
