What happens to precocious heart disease? What is the cause? Precocious heart disease is a heart malformation caused by a defective or partially arrested development of the fetal heart in the mother’s body, with an incidence of about 0.8%. The pathogenesis of precocious heart disease is not yet well understood, but it may be due to external disturbances to the mother during early pregnancy, especially in the first three months, especially viral infections, chemical factors, radiation, etc., resulting in abnormal development of the embryo and causing precocious heart disease. What are the symptoms that indicate the possibility of precocious heart disease? （A large percentage of children are found to have a heart murmur by the physician at the time of the visit. The following symptoms should be considered when a child is irritable, has a high pitched cry, weakness in sucking during feeding, shortness of breath, shortness of breath after crying or activity, and blue lips. In those children with cyanotic precordial disease, the fingernails, lips and cheeks may be dark purple, which is medically known as cyanosis or cyanosis. Some children may also have swollen lower extremities and pestle-like toes. In addition, children with precordial disease are usually prone to recurrent lower respiratory infections and growth retardation. Some children also have malformations of other parts of the body or delayed intellectual development. When parents notice the above symptoms in their children, they should think about the possibility of precardiac disease. If the child cries repeatedly after birth or is unable to eat well, consider the possibility of congenital heart disease. In general, children with severe precocious heart disease can show symptoms in infancy (up to 1 year old). Regardless of the type of congenital heart disease, a definitive diagnosis can only be made after a detailed examination by a specialized cardiologist, which will also include ancillary tests such as chest x-ray, electrocardiogram, and echocardiogram. What are the risks to my child if he or she has preeclampsia? Generally, the severity of the disease varies, but it can affect the child’s growth and development to varying degrees, reduce resistance, and also heart failure, infective endocarditis, and other serious conditions can be life-threatening. And part of the children with precocious heart disease is the development of the disease with age, if not timely treatment, pulmonary artery pressure increase or heart enlargement, to the late stage will lose the opportunity to treat. It is well documented that half of the children with untreated precardiac disease die at age 1 and 2/3 of them die at age 2. Some simple precocious heart diseases that do not have obvious physical effects may also cause psychological stress in school, employment, marriage and society if left untreated. When is the best time to operate for precocious heart disease? The principle of treatment for precocious heart disease is generally early detection, early diagnosis and early treatment, but the earlier the surgery, the greater the risk and the test of surgical level. Once the heart disease is clearly identified, the appropriate treatment is decided according to the type of heart disease, and some may require immediate corrective surgical procedures. Some common congenital heart diseases, such as atrial defect, ventricular defect, patent ductus arteriosus, pulmonary valve stenosis, cyanotic congenital heart such as Tetralogy of Fallot, etc. A small number of patients with relatively small defects can heal on their own even within one year of age. Surgery for congenital heart is divided into two types of surgery and interventional surgery, sometimes both types of surgery are needed. The majority of congenital heart disease can be cured and completely reach the normal level of life, and some congenital heart disease can approach the normal level of life after surgery. The treatment of congenital heart disease should follow the advice of a professional cardiologist. What should patients with congenital heart disease pay attention to in their daily life? Children who already have congenital heart disease, one is to avoid infections, because many congenital heart disease infections, such as after a cold, very easy to develop into lower respiratory tract infections, respiratory tract infections are serious, it will pose a threat to the life of the child. Secondly, children with congenital heart disease are not suitable for excessive sports or activities because it may increase the extra burden on the heart, and some children may suffer from panic or fainting as a result. General daily activities are fine, but not excessive exercise. Is it possible to cure congenital heart disease without surgery? Interventional treatment for congenital heart disease is the same as the interventional treatment for coronary heart disease, which you may be very familiar with. It uses a very thin catheter to deliver a split plug umbrella device to the heart through the child’s blood vessels to plug the gap for the purpose of curing congenital heart disease. Interventional treatment of congenital heart disease has been carried out in the world and in China for nearly 50 years. In the past 17 years, due to the development of blockers and other related interventional devices, most of the arteriovenous catheter failure can be treated with interventional therapy, and the success rate is up to 98% or more, and very few late complications occur; the success rate of interventional therapy for atrial septal defect with secondary holes and good marginal conditions is up to 97% or more; the success rate of interventional therapy for ventricular septal defect is up to 95 The success rate of interventional treatment for ventricular septal defect is more than 95%, and the serious complications are further reduced, especially the number of cases requiring permanent pacemaker implantation after surgery for third-degree AV block is significantly reduced; for typical pulmonary valve stenosis, PBPV has basically replaced surgery. According to conservative estimates, 66%-70% of precordial diseases can be cured by interventional therapy, the advantages of which are: 1. 2, no extracorporeal circulation, deep hypothermia anesthesia, can avoid the occurrence of extracorporeal circulation and anesthesia accidents, and will not affect the brain development of children. 3.Low bleeding, no blood transfusion, avoiding the possible adverse reactions caused by mathematics. 4.Short surgery and hospitalization time, quick recovery after surgery, general hospitalization time 4-7 days.
