Fale IV is a common congenital heart disease, also known as cyanotic tetralogy of Fallot, which is a combined congenital cardiovascular malformation. The disease includes ventricular septal defect, pulmonary artery orifice stenosis, right aortic position (riding over the defective ventricular septum) and right ventricular hypertrophy, of which the first two malformations are the basic lesions, and the disease is a better common congenital cardiovascular disease of cyanosis. Patients with only ventricular septal defect, pulmonary artery orifice stenosis and right ventricular hypertrophy without aortic riding are referred to as atypical tetralogy of Fallot. The incidence is about 11-13% of precardiac disease, with similar proportions of men and women. So what is the outcome of treatment for adults with falciparum tetralogy? In recent years, with the development of medical science, the mortality rate of fatal tetralogy & surgery has decreased significantly, the mortality rate of infants and children is only 3-5%, and the mortality rate of adult fatal tetralogy surgery is 3-14%. Of course, the success rate of adult F4 surgery is closely related to the experience of the surgeon. In general, the causes of early postoperative death in adult F4 patients are usually low cardiac output syndrome, perfused lung or pulmonary edema, renal failure, pericardial tamponade, arrhythmias, and infection. The vast majority of patients recover well after surgery, cyanosis, hypoxemia, etc. can disappear immediately, pestle finger (toe) gradually return to normal, but most patients can still hear varying degrees of heart murmur. Patients can work and study normally, get married and have children, and do not need long-term medication. Indications for surgery in adults with French IV: 1, the diagnosis is clear, the general condition is fair, and non-surgical treatment cannot improve the symptoms; 2, no contraindications to surgery for French IV are found; If the indications for surgery are met, then the expert French IV is not treated in time as a child, and as the body’s developmental compensatory mechanisms take effect, more collateral vessels of the main pulmonary artery will appear after adulthood, and when the collateral branches are formed, in order to correct the cardiac vascular malformation. If reluctantly do surgical operation, may be more bleeding after adult French IV surgery, also prone to postoperative complications, and with the emergence of hybridization surgery, the above existing surgical risks can be basically solved by first interventional blocking of the collateral vessels before surgery, ensuring the safety and surgical results of French IV surgery. Compared with traditional surgical procedures, hybridization surgery becomes simpler for the surgeon, better for adult F4 patients, and reduces medical costs for F4 patients, alleviates patient pain, and results in faster postoperative recovery.
