1.Pediatric congenital heart disease Congenital heart disease refers to congenital heart malformations caused by abnormal development of heart vessels during fetal period. Common congenital heart diseases include: ventricular septal defect, atrial septal defect, patent ductus arteriosus, pulmonary stenosis, tetralogy of Fallot, etc. 2.What is related to pediatric precocious heart disease? It is generally believed that it is related to the mother’s viral infection in early pregnancy, the use of certain drugs, exposure to toxic substances, radiation and other harmful factors, so that the development of the fetal heart is affected. 3.What are the common manifestations? Children with precocious heart disease are more prone to colds and pneumonia, and their symptoms are more severe after the disease. Children with cyanotic precocious heart disease show cyanosis around the mouth, pestle-like fingers (toes), and squatting when walking. In addition, such as shortness of breath, easy sweating, poor mobility, feeding difficulties, growth retardation is common. 4.How to confirm the diagnosis? If a child is found to have upper surgery, he/she should go to a regular hospital for cardiac surgery in time for early diagnosis and treatment. Cardiac ultrasound and chest X-ray are the main means of diagnosing pediatric precocious heart disease, for some complex or unclear precocious heart disease, it is necessary to perform cardiac catheterization or spiral CT and other tests. 5, the timing of treatment of pediatric precocious heart disease Different types of precocious heart disease have different optimal treatment timing, in short, the earlier the treatment, the smaller the impact on the growth, development and function of the child’s systems. Because of the strong specialization of cardiac surgery, so when you know your child is suffering from precocious heart disease, you must go to a regular hospital that can carry out cardiac surgery to guide the treatment, so as not to miss the best time for surgery, increase the cost of treatment, and affect the results of surgery. 6.What is the effect of treatment of pediatric precocious heart disease? Most of the children with precocious heart disease can be cured by surgery or interventional treatment, and can grow up healthy and happy as normal children.
