The goal of minimally invasive surgery is to minimize the immediate and long-term trauma and disturbance to the local tissues and overall internal environment. The best results are obtained with minimal trauma. This is the goal we have been pursuing, and we have achieved good results, which we would like to share with those who need it. I divide minimally invasive cardiac surgery into two categories: the “visible” minimally invasive and the “invisible” minimally invasive. ”Visible” minimally invasive means that the incision is small, or even not visible. For cardiac surgery, the incision we commonly use is the median sternotomy. The length of the incision is as long as the sternum in front of the chest, so let me show you an image: the long incision, the trauma, and the tendency to develop a chicken chest are the disadvantages that have always bothered us. The same procedure is done with a 1.5cm or even smaller incision. Of course, the location of the incision may vary depending on the situation, but the length of the incision is very small. I call this “visible” minimally invasive. It has the advantages of minimal trauma, quick recovery, and no sternal deformity. This incision is ideal for blocking simple cardiac anomalies such as ventricular septal defects and atrial septal defects, and it avoids extracorporeal circulation, minimizing the damage to the child. For children who are not suitable for surgical occlusion, the following incisions can also be used: 1. Right axillary incision: small, concealed and without sternal deformity. 2.Small median sternal incision: about half the length of the conventional incision, and the uppermost edge of the incision is located at the level of the nipple line. It also has the advantages of small wound and concealment, and has wider indications. Most simple congenital heart diseases can be treated with the above-mentioned minimally invasive procedures. For complex cardiac anomalies, we still use conventional incisions, but at the same time follow a minimally invasive concept that minimizes the physiological trauma to the child, i.e., “invisible” minimally invasive. The “invisible” minimally invasive approach is more practical in that it is invisible from the outside, but does reduce the damage to the internal structure and physiology of the body. It is a more technically demanding procedure that is used by every surgeon in our practice! In fact it should be more “minimally invasive” than a small incision. This includes the selection of the timing of surgery, the design of the surgical plan and procedure, the surgical technique, and the multidisciplinary and multidisciplinary cooperation. However, there are certain limitations, which are guaranteed by a team of stable techniques and advanced equipment. For example, we maintain the lowest surgical mortality rate under the premise of very high surgical complexity; we use the most advanced extracorporeal circulation machine, membrane lung, blood recovery machine and myocardial protection fluid in the industry to minimize the injury of extracorporeal circulation in children; neonatal transposition of the great arteries can be discharged from the ventilator 1 day after surgery and discharged from the hospital in one week.
