Congenital heart disease Atrial septal defect is a common congenital heart disease. According to the clinical data in Beijing and Shanghai, atrial septal defect accounts for 24.6% and 265,438 0.7% in various congenital heart diseases, respectively. Congenital heart disease is more common in women, and the ratio of male to female is 2∶ 1 ~ 4∶ 1. Atrial septal defect (ASD) in congenital heart disease is caused by the hypoplasia of related tissues that constitute atrial septum in embryonic period. Some small cases of atrial septal defect with type 2 congenital heart disease may close automatically within 1 year after birth, and it is extremely unlikely to close automatically two years after birth. The ratio of pulmonary circulation blood flow to systemic circulation blood flow exceeds1.5:1.5, so surgical treatment should be considered. The most suitable age for surgery is 4 ~ 5 years old. Early surgical treatment can prevent the increase of pulmonary circulation resistance and right heart failure. Infants with congestive heart failure should be operated as soon as possible if the heart failure cannot be controlled by medical operation. As far as your little darling is concerned, it is possible to naturally close the 4MM atrial septal defect of congenital heart disease, and there is no need for treatment at present. It is recommended to have a cardiac ultrasound once a year. If the atrial septum tends to increase obviously, exceeding 5mm, it is recommended to have surgery (atrial septal defect repair) at the age of 4. Because of what children remember after they are four years old. The success rate of atrial septal defect repair is basically 100%. If surgery is recommended, it is recommended to repair atrial septal defect in the hospital where the right axillary cosmetic incision is performed.

In developed countries, interventional occlusion is limited to muscular ventricular septal defect and patent ductus arteriosus. In the past, developed countries also intervened to block atrial septal defect. Because of many problems, this method was eliminated. I hope the above reply is helpful to you.
