Coronary artery disease is a heart disease caused by relative or absolute ischemia and hypoxia of the myocardium due to coronary atherosclerosis and functional changes in the coronary arteries (e.g. spasm), also called ischemic heart disease. When the stenosis reaches 75%, it will significantly affect the blood flow and produce angina symptoms. In this case, interventional stenting or surgical bypass surgery is required. Coronary artery bypass grafting is the creation of a vascular pathway with a grafted vessel (often the internal mammary artery, radial artery, and saphenous vein) distal to the aorta and coronary artery download, allowing blood to bypass the stenosis and reach the distal end. For diffuse stenosis of multiple coronary arteries bypass surgery is required. In particular, surgical treatment should be considered for patients with multiple vascular lesions, a history of myocardial infarction, combined diabetes mellitus, and poor cardiac systolic function. Coronary artery disease combined with valvular disease, ventricular wall tumors, congenital heart disease or cardiac tumors should also be treated surgically. Traditional surgery is usually performed under general anesthesia, hypothermia, extracorporeal circulation, and cardiac arrest, and generally takes 3-4 hours. With the development of new technologies, more and more patients can be treated with non-extracorporeal circulation non-stop coronary artery bypass grafting, which significantly reduces the damage to the patient and results in faster postoperative recovery. In recent years, cardiologists and cardiac surgeons have been working together to implement “hybridization” for high-risk patients with multiple lesions. Hybridization means that the physician performs stenting of the diseased coronary artery through interventional techniques, while the surgeon performs a small incision bypass surgery on the most important left anterior descending vessel. It ensures the therapeutic effect while minimizing the trauma caused by the procedure and significantly shortening the hospital stay.
