1, no thoracotomy, less trauma. For children, interventional therapy can make the chest scar-free without affecting the appearance, avoid unnecessary troubles in further education, employment and even marriage, and is conducive to the cultivation of self-confidence of children with congenital heart disease.
2. Less complications and high safety. The complications such as residual leakage of atrioventricular septal defect and patent ductus arteriosus recanalization in some patients after traditional thoracotomy were completely avoided.
3. Short hospitalization time and quick postoperative recovery. Closure of patent ductus arteriosus, atrial septal defect and ventricular septal defect requires 1 ~ 2 hours. The next day, the patient can work in the fields and return to normal life. After observation for 3-7 days, normal study and work can be resumed. The average hospitalization time was 5 ~ 10 days. 4, the long-term treatment effect is good. After the occluder was implanted in the heart 1 month, the human body's own endothelial cells covered its surface, and after 3 months, the endothelial cells were completely embedded and fixed the occluder. After nearly 10 years of follow-up, the patients with congenital heart disease after interventional therapy have fully recovered, their growth and development have not been affected, and they can be as competent as healthy people in work, study and life; Marriage and childbirth are not affected.
