With the continuous improvement of living standards, people’s requirements for improving the quality of life, beauty and psychology are also getting higher and higher. Most of the traditional heart surgeries are mainly performed with a median incision, which requires sawing through the sternum and causes greater trauma to the patients. Due to the destruction of the integrity of the sternum, postoperative patients tend to have more pronounced pain and the whole recovery process is relatively long, and they still have hidden pain even after a period of time when they encounter rainy and humid weather. For some young patients, the psychological shadow caused by the obvious scar in the middle of the chest lingers for a long time and seriously affects their future life and social life. Since the 1990s, some minimally invasive procedures in cardiac surgery have been gradually carried out internationally. Especially in recent years, minimally invasive surgery has been accepted by more and more surgeons and welcomed by patients for its less invasive, resource-saving and cosmetic reasons. So what is minimally invasive? Minimally invasive is the use of smaller incisions to perform procedures that previously required greater trauma with less trauma. Minimally invasive surgery has been widely developed because of the reduction of trauma, which makes the whole treatment process significantly shorter and the patient’s recovery significantly better than before, so that both doctors and patients can benefit from it. Currently, we perform over 500 minimally invasive surgeries each year, including minimally invasive mitral valvuloplasty and replacement, minimally invasive aortic valve replacement and TAVI surgery, minimally invasive multivalve replacement, minimally invasive atrial and ventricular defect repair, minimally invasive atrial fibrillation ablation, as well as minimally invasive thoracoscopic surgery, robotic valve and coronary artery bypass surgery. The surgical incision has been shortened from 20-30 cm to 4-5 cm or even 1-2 cm, and the hospitalization time has been shortened from about two weeks to 4 or 5 days after surgery. It has been proved that the advantages of minimally invasive surgery have been fully demonstrated by the obvious reduction of surgical trauma and pain, the obvious reduction of blood transfusion rate and transfusion volume, the obvious shortening of recovery period, and the obvious cosmetic effect. With the increasing maturity of surgical methods and the increasing perfection of operating instruments, it is believed that minimally invasive surgery will develop more safely and vigorously.
