Traditionally, coronary artery bypass surgery is performed with extracorporeal circulation and the heart stopped beating, but extracorporeal circulation can stimulate a systemic inflammatory response to a certain extent, causing certain effects on the body’s tissues and organs. Minimally invasive coronary artery surgery can avoid these disadvantages and reduce the trauma of the surgery to the body. On the premise of ensuring the efficacy, minimally invasive coronary surgery, including non-stop bypass surgery, robotic bypass surgery and coronary hybrid surgery, which aims to minimize the trauma, has become the development direction. 1.Non-stop coronary artery bypass surgery does not use extracorporeal circulation, and the bypass is done under the beating heart. Since 2000, most of the coronary artery bypass surgery in PLA General Hospital adopts the minimally invasive non-extracorporeal circulation surgery method, and has completed 1500 cases continuously. The success rate of the procedure is almost 100%. 2. Robotic coronary artery bypass is the most advanced and minimally invasive coronary artery bypass technique in the world. It is performed by the Davincy robotic system to free the internal mammary artery and complete the anastomosis with the corresponding coronary artery under the condition of non-extracorporeal circulation without stopping. The greatest benefit is that the bypass surgery can be completed without opening the chest or by making a small intercostal incision in the chest wall, without the use of extracorporeal circulation, which greatly reduces the trauma of the surgery, and the surgical result is the same or even better than that of open-heart surgery. At present, the PLA General Hospital routinely carries out robotic coronary artery bypass surgery and has completed more than 100 cases. 3. Hybrid coronary artery surgery (Hybrid) is an internationally advanced concept and technology for the treatment of coronary heart disease. For patients with limited stenosis of the gyral branch or right coronary, robotic open-heart bypass surgery of the internal mammary artery and the anterior descending branch is completed, and then stent placement is performed in the right coronary or gyral branch. Hybrid surgery can achieve minimally invasive surgical treatment of multiple vascular lesions. It combines the respective advantages of minimally invasive surgery and stenting, and minimizes trauma while ensuring the treatment effect. Currently, the PLA General Hospital has completed more than 10 cases of coronary artery hybridization surgery with good results. In general, traditional coronary artery bypass surgery is well developed, and minimally invasive coronary artery bypass with the purpose of reducing trauma is the direction of development, but minimally invasive bypass requires high skills of the main surgeon and anesthesia technology, and is selective for cases, not all patients are suitable for non-stop surgery or robotic surgery, and treatment plans need to be selected according to individual conditions so that patients can be treated with the least trauma and the best efficacy.
