A. Treatment of congenital heart disease: small trauma and strict indications Participation blocking surgery is a new type of minimally invasive treatment developed in recent years, which relies on complete equipment, advanced catheterization laboratory and skilled specialists, and is mainly applied to children with unclosed arterioles, atrial septal defects and partial septal defect divergence and other malformations requiring surgical correction. Participation in blocking treatment is relatively less complications, less trauma, no need for open-heart surgery, fast recovery, less patient pain, hospitalization time of about 3 days, but it has more strict indications, the cost is relatively high compared to surgical procedures. The new technology of surgical minimally invasive blocking is also emerging in the last two years. It does not require opening the chest, but a 2-3 cm small opening in the right anterior sternum, placing a pusher, and under the guidance of cardiac ultrasound, opening the blocker to block the gap. This treatment for congenital heart disease takes less than 1 hour for an even operation, and the patient is able to go down on the same day of the operation and is hospitalized for 3-4 days. It is suitable for patients with partial atrial septal defect, ventricular septal defect and unclosed arterial duct. The traditional surgical open-heart surgery is the main treatment method, which is generally applicable to all simple and complex precardiac diseases (e.g., combined pulmonary hypertension, Tetralogy of Fallot and other heart diseases with cyanosis). Compared with other surgical methods, open-heart surgery is less expensive and the hospital stay is about 7-10 days, but the surgery is more traumatic than other methods and the postoperative recovery is slower. With the advancement of cardiac surgery technology and the demand of society, minimally invasive cardiac surgery with small incisions is progressing more rapidly. The advantages of this treatment for congenital heart disease are less painful, faster recovery, and better aesthetic results, which are easily accepted by patients and their families. The heart is one of the most important places in the human body, and a slight failure may bring great harm to a person. If you have symptoms similar to cardiothoracic disease, do not hesitate to go to a regular hospital for diagnosis. Our hospital has done a large number of patients, and after years of follow-up, the results are very good.
