Tetralogy of Fallot

Tetralogy of Fallot is a combination of pulmonary stenosis, ventricular septal defect, aortic stride, and right ventricular hypertrophy. About 10% of congenital heart disease. Patients with bruising and clubbing fingers, breathing quickly during activities, squatting or purpuric episodes, that is, bruising aggravated, breathing faster, difficult, severe and even dizziness are the most obvious symptoms. There may be murmurs in the precardiac area, end-occlusion (5% -10%), pulmonary valve stenosis (5% -8%), etc., which account for about 60% of congenital heart disease. For the cardiovascular malformations listed above, the current surgical treatment is basically safe and reliable unless the operation is accidental, and the postoperative can live and work like normal people. Although surgical treatment of complex congenital heart disease is still being explored, tetralogy of Fallot's tetralogy, which accounts for 10% of congenital heart disease, currently has a success rate of more than 95%. Other complicated operations, such as endocardial cushion defect, pulmonary vein malformation drainage, double outlet of right ventricle, and single ventricle, have also achieved good results. Reduction surgery is a necessary operation to improve the condition of children with complex congenital heart disease before radical surgery can be completed. For example, in children with poorly developed pulmonary arteries, body arterial or pulmonary arterial bypass or body vein or pulmonary arterial bypass surgery can promote pulmonary artery development and increase the success rate of future radical surgery.
