Congenital heart disease (congenital heart disease) has the following advantages over traditional open-heart surgery: Less traumatic: no incision is required on the back of the chest, only a 2 to 3 mm incision in the groin (usually no scarring). There is no need to open the chest cavity and pericardium, much less cut open the heart, and there is almost no damage to the heart. The wound does not need to be sutured, leaving no obvious scars, and the patient can take a shower 5 to 6 days after the procedure, which brings a lot of convenience to the patient. Short operation time: The operation time of interventional treatment is short, for example, it only takes about 30 minutes to seal an atrial septal defect, and the child can get up and move around 6 to 12 hours after the operation, and can be discharged from the hospital in 3 to 5 days. Fast postoperative recovery: the child can get up and move around on the 2nd day after surgery. Almost no rejection: Since the blockers currently used are made of nickel-titanium memory alloy, they are non-antigenic and do not cause rejection in the child’s body. No need for blood transfusion: Because of the low bleeding of the intervention, no blood transfusion is needed, avoiding infectious diseases that may be caused by blood transfusion, such as hepatitis and AIDS. Avoid arrhythmias caused by open-heart surgery: The scar left on the heart by open-heart surgery may lead to scar-related arrhythmias, and interventional procedures do not have this complication. No need for general anesthesia: only local anesthesia in the groin, avoiding the accident of general anesthesia and the toxic side effects of general anesthesia on the brain, liver, kidneys and other organs, especially avoiding the effects of anesthetic drugs on the intellectual development of children’s brains. The cost is basically comparable to surgical treatment: the interventional blocking technique for precordial disease is a revolutionary technique and a blessing for many patients with precordial disease. I hope that doctors and patients’ families will understand that this technique is not only a radical technique but also a cosmetic technique.
