The most traditional, thorough and classic method of cardiac surgery to treat congenital heart disease is to adopt a median sternotomy incision, which is suitable for almost all types of congenital heart disease because the incision is made from the median sternum, exposing the whole heart to the view. However, the disadvantage of this congenital heart disease treatment method is that more blood is lost during the surgery and a long scar is left on the chest after the surgery, which not only affects the aesthetics but also traumatizes the patient after the surgery. For patients with simple congenital heart disease, such as patients with patent ductus arteriosus, atrial septal defect, ventricular septal defect and pulmonary valve stenosis, minimally invasive surgery for congenital heart disease, such as thoracoscopic-assisted small incision atrial defect repair and transthoracic minimally invasive atrial/ventricular defect closure, can be used to achieve benefits such as reduced trauma, cosmetic appearance and cost savings. Minimally invasive surgery for congenital heart disease has many advantages – four types of congenital heart disease can choose minimally invasive With the development of cardiac surgical treatment technology, at the same time, the patient’s demand for surgical results has gradually improved, and some minimally invasive heart surgery aimed at reducing damage and minimizing the appearance has emerged. Minimally invasive surgery is the future of cardiac care. Simple patent ductus arteriosus, atrial septal defect, ventricular septal defect and pulmonary stenosis can be treated minimally invasively, but not all congenital heart diseases can be treated minimally invasively, depending on their specific conditions. In the experience of cardiothoracic surgery, nearly half of congenital heart diseases can be treated minimally invasively. Minimally invasive surgery requires a certain age and weight of the child with congenital heart disease. Minimally invasive surgery of the heart generally requires the best approach to ensure the least trauma, the best internal environment, and the least psychological trauma for the patient, given the current level of technology. Minimally invasive transthoracic occlusion, which requires no extracorporeal circulation, is performed through a small incision in the right chest under general anesthesia and ultrasound guidance, resulting in rapid recovery and minimal injury to the patient; thoracoscopic assisted small incision atrial/ventricular defect repair, which is performed through a 3-5 cm incision in the right chest, with the thoracoscope entering through the incision and performing minimally invasive repair under thoracoscopic guidance. Minimally invasive heart surgery for congenital heart disease is demanding Minimally invasive surgery for congenital heart disease has several benefits: less damage, faster recovery, and only minimal scarring after surgery. Most patients with congenital heart disease are under the age of 18, which leaves long scars on their chests that can have a significant impact on their lives later in life. The key elements of minimally invasive surgery for congenital heart disease are equipment and technique. A median sternal incision exposes the entire view of the heart, while minimally invasive surgery only exposes part of the view of the heart, and the rest depends on the surgeon’s experience and the intervention of imaging equipment. Although there is no large scale statistical data to show what percentage of congenital heart disease can be treated with minimally invasive treatment, about half of the patients with congenital heart disease can be treated with minimally invasive treatment according to the patients operated by cardiothoracic surgery. Our department has successfully carried out minimally invasive surgery for congenital heart disease, and several children have achieved satisfactory results and have been discharged from the hospital, which has proven to be more effective than traditional open-heart surgery for patients.
