Pulmonary valve balloon dilation

Stenosis can occur in valves and blood vessels. The most common congenital valvular stenosis is the pulmonary valve and aortic valve. The mitral and mitral stenosis are rare, and the most common stenotic vessels are the main artery and pulmonary artery. Cardiac catheter treatment of pulmonary valve stenosis was first reported by Semb et al in 1979. In 1982, Kan et al. first successfully expanded a stenosis of a child with an eight-year-old pulmonary stenosis with a balloon catheter, and the pressure difference between the right ventricle and the pulmonary artery decreased from 48 mmHg to 14 mmHg. Since then, balloon catheter dilatation has been widely used in pulmonary stenosis, peripheral pulmonary stenosis, aortic stenosis, and aortic coarctation, and has become the standard treatment for these stenotic deformities. Treatment of diseases: pulmonary valve insufficiency Indication Pulmonary valve stenosis. Preoperative preparation Antibiotics are routinely used before surgery. Surgical procedure The expansion method is to send a balloon catheter through the femoral vein to the stenosis of the pulmonary valve, inject the developer, and then inflate the balloon with sputum to five atmospheres, and simultaneously expand the valve. The pressure difference between right ventricular pressure and valvular stenosis immediately after dilation is reduced. complication The expansion method is to send a balloon catheter through the femoral vein to the stenosis of the pulmonary valve, inject the developer, and then inflate the balloon with sputum to five atmospheres, and simultaneously expand the valve.
