1.Is there any possibility of self-healing of congenital heart disease? Some congenital heart diseases have the possibility of self-healing, such as arteriovenous ductus arteriosus within 3 months (especially in premature babies), atrial septal defect has the possibility of self-healing within 2 years of age, some membrane and muscle septal defects can be followed up according to the situation, generally there is a chance of self-healing before 5-7 weeks of age, but most of them occur within 1 year of age, children need to be followed up under the guidance of a specialist to observe the condition, if there are If complications arise, early intervention is necessary. If the defect heals spontaneously, then surgery is not required, which is the best outcome. However, if the defect never closes, then surgery is required. 2.When is it better to operate for congenital heart disease? When is the best time to operate on a child with congenital heart disease is related to the type of disease in the child. For common congenital heart diseases such as atrial septal defect, membranous and muscular ventricular septal defect, and patent ductus arteriosus, if the child has no obvious symptoms and normal growth and development, then he or she can be followed up with regular ultrasound and under the guidance of a specialist, and if the defect remains unclosed, interventional or surgical treatment can be performed in preschool. However, if the child has slow growth, repeated pneumonia, uncontrollable congestive heart failure, persistent increase in pulmonary artery pressure, etc., then early surgery should be performed. 3.Is it better to treat congenital heart disease with interventional therapy or open-heart surgery? If the child’s condition allows, interventional treatment is less traumatic, faster recovery and more effective, and interventional treatment has been increasingly used to treat congenital heart disease. However, interventional treatment has certain indications. If the child’s condition does not allow, is not suitable for interventional treatment or is in serious condition, then open-heart surgery should be performed early. 4.How much does interventional treatment for conventional atrial septal defect, ventricular septal defect and patent ductus arteriosus cost? The cost of conventional atrial septal defect and ventricular septal defect is about 30,000 (including hospitalization, medicine, examination and interventional surgery); the cost of general arteriovenous catheterization is about 20,000 (including hospitalization, medicine, examination and interventional surgery). 5.What should children with congenital heart disease pay attention to on a regular basis? In children with congenital heart disease, such as the common congenital heart disease with multiple types of pulmonary blood such as arteriovenous ductus arteriosus, atrial septal defect and ventricular septal defect, blood is shunted from left to right in a large amount, the pressure of pulmonary artery increases, thus causing water to leak into the alveolar interstitium, water and blood in the lung increases, pulmonary compliance decreases, and labored breathing and choking occurs, and when the heart function is affected, it causes pulmonary stasis and edema. A slight upper respiratory infection can easily cause bronchitis or pneumonia; in addition to this, excessive sweating, feeding difficulties, and growth retardation may occur. Therefore, children should be careful to avoid colds and flu, to feed them reasonably, and to have their heart ultrasound checked regularly and to follow up with the pediatric cardiology clinic.
