Parents ask: My child is 6 months old and has a congenital heart disease with ventricular septal defect, repeated pneumonia, feeding difficulties, and weight gain. There is also a non-invasive method is interventional therapy, but it is also very risky and subject to prolonged X-ray radiation, the interventional doctor said my child’s age and type of disease can not do interventional therapy, help whether there is a safe and effective way to solve our “heart disease”. The expert answer: this child belongs to the left-to-right shunt type of precordial disease, this type includes ventricular septal defect, atrial septal defect, arteriovenous ductus arteriosus three kinds of heart malformation, together accounting for 60% of precordial disease, the treatment currently has three kinds: traditional surgical open-heart surgery, medical intervention, surgical minimally invasive blocking, but the first two bring the patient side damage are very serious, so experts prefer to choose surgical minimally invasive blocking. What kind of damage is there? Below we introduce you in detail: Traditional cardiac surgery is undoubtedly a major surgery, patients have to “open the belly”, the incision is about 20cm long, sawing open the sternum, cardiac arrest incision, extracorporeal circulation and a large number of blood transfusions, many children with precordial disease cured deformity, the long scar in front of the chest and become a “heart disease”. Internal interventional therapy, on the surface, he has little damage to the human body and fast recovery, but in essence it is far more harm and impact on the human body than traditional surgical open-heart surgery, the greatest damage to the human body is X-ray damage, the patient is not any protection, completely exposed to the X-ray machine irradiation almost accompanied by the entire operation, pediatric sensitivity to X-rays 10 times greater than middle-aged people, on the gonads, thyroid and white blood cells and The effects on the gonads, thyroid and white blood cells and intelligence are very significant. The second is the damage to the blood vessels. The interventional catheter is delivered to the heart through the femoral artery at the root of the thigh, so it produces irreversible damage to the endothelium, and the blocker is easily dislodged during re-intervention, with a higher incidence of incomplete blocking, heart valve damage, and arrhythmia. Minimally invasive surgical umbilical occlusion is an international cutting-edge technology for the treatment of ventricular septal defect, atrial septal defect and patent ductus arteriosus, and is a new medical model – Hybrid therapy, which is the pursuit of medical humanization and has been commonly used and matured at home and abroad. The procedure is as follows: a small incision of 2cm is made in the hidden part of the chest to expose the local surface of the heart, a thin catheter is inserted, and through the guidance of real-time ultrasound, the catheter reaches the defect and a blocking umbrella is delivered to repair the affected area, thus achieving the purpose of treatment. The whole operation takes about 30 minutes, with little trauma, little bleeding, no extracorporeal circulation and blood transfusion, and the patient can eat and get out of bed in 6 hours, with a hospital stay of 3-5 days and a hospitalization cost of about 20,000; the delivery system is short and straight instead of the thin and curved sheath of internal intervention, which is suitable for more than 90% of left-to-right shunt precordial diseases and is more conducive to manipulation, thus improving the accuracy and safety of the operation; it is performed in the operating room. It facilitates the handling of emergencies and makes the procedure safer; it does not require X-ray radiation, does not use contrast agents, and has no vascular damage. The application of this technology has created a new era in the treatment of precardiac disease.
