The heart is one of the most important organs in the human body, and its delicate and complex structure, once damaged, is often difficult to repair on its own and often requires surgical reconstruction. However, because the heart is closely protected by the sternum, ribs and spine, traditional heart surgery requires a median sternal incision of about 30 cm, which is very traumatic, bleeding and slow to recover, and may bring the risk of poor sternal healing, reduced stability of the thorax and even mediastinal infection. In addition, for young patients, the median thoracic incision affects the aesthetics and brings a certain negative impact on their future life and psychology. How to minimize the physiological and psychological trauma of cardiac surgery patients has always been a problem for cardiac surgeons to ponder and study. In the past two years, with the rapid development of minimally invasive surgical instruments and equipment, minimally invasive cardiac surgery methods in developed countries in Europe and America have been finalized and matured, and minimally invasive cardiac surgery has been routinely carried out in a few hospitals with strong technical strength in China. In addition to mastering all the skills of conventional cardiac surgery, the surgeon in charge of minimally invasive cardiac surgery needs long training to adapt to the different views provided by small incisions or thoracoscopic cameras, and to be able to operate various special minimally invasive instruments and equipment, another requirement for the surgeon is to be more careful and patient, and to be able to deal with various special situations in a timely manner. The most advanced and reliable minimally invasive technology in the world today, the “da Vinci” robotic system for total endoscopic cardiac surgery, is also routinely performed in Zhongshan Hospital. With the help of the da Vinci robot, the three-dimensional magnified image of the patient’s heart is displayed in real time and clearly in front of the doctor’s eyes, and the surgeon in charge of the operation can manipulate the robot outside the patient’s body to complete complex operations such as heart valve repair, coronary artery anastomosis, atrial septal defect repair and heart tumor removal with flexibility and precision. All these operations can be completed through only a few small holes in the patient’s chest wall, making it a true open-heart heart surgery. What cardiac surgeries can be performed with “minimally invasive” techniques? Simple mitral valve replacement or repair, tricuspid valve replacement or repair, aortic valve replacement, atrial defect repair, and mucosal aneurysm removal can all be performed through a minimally invasive right thoracic incision. Coronary artery bypass grafting (severe stenosis of the anterior descending or diagonal branches) can be done through a minimally invasive left thoracic incision using the da Vinci robotic system. The history of “mega-invasive” surgery is gone, and good “minimally invasive” technology enables patients to obtain the best results with minimal trauma. She continues to change the mindset of surgeons and our lives.
