Patients who are 4 months old or older can be considered for interventional treatment, and it is a one-time radical treatment with little pain, no surgical scar, safe interventional treatment and reliable efficacy. At present, open-heart surgery is generally not necessary for this type of precordial disease. Of course, an experienced surgeon should be consulted for interventional occlusion. After the interventional blocking of the arterial ductus arteriosus, the body tissue will be covered with the blocker after a few months, and the original unclosed arterial duct will be closed and the precordial disease will be completely cured. No matter how the child grows up, the blocker is already firmly bonded to the patient’s tissue, so how can it be reopened with age? Let’s use an analogy: If someone has an unfortunate hand injury when they are a child, the wound is long and deep, and after treatment the wound heals completely. Years later, when the child grows up and the hand slowly grows, will the wound that has healed open on its own? Whether it is the case of arteriovenous catheterization, other precordial diseases such as atrial septal defect, ventricular septal defect, coronary artery fistula, etc., after the successful blocking of the patient is healed, no matter how the child grows up, the blocker is already firmly combined with the patient’s tissue to form one, and it is impossible for the blocker to fall off as the patient grows older and the organ grows up, and it is completely cured.
