Coronary artery bypass surgery, or coronary artery bypass grafting, is an open-heart procedure. Patients with coronary artery disease should follow their physician’s advice and choose the appropriate surgical procedure according to their condition. Coronary artery bypass grafting under physical circulation requires open chest treatment under general anesthesia and requires cardiac arrest and extracorporeal circulation. However, it is not suitable for people with severe systemic diseases, chronic heart failure, or severe irreversible changes in cardiomyopathy. In contrast, non-corporeal bypass surgery can be performed under cardiac arrest, with an incision in the middle of the sternum, and is generally used for lesions caused by the left anterior descending and right coronary arteries. Minimally invasive direct visualization coronary artery bypass grafting can also be used in the treatment of coronary artery disease. Although the incision of this approach is smaller, it also requires open chest treatment, and the commonly used incisions are left anterolateral thoracic incision, left posterolateral thoracic incision, and subxiphoid incision. However, this type of surgery cannot be performed if it is associated with refractory arrhythmia, decompensated heart failure, or if the surgical instruments are inaccessible or the target vessel is small. Patients with coronary artery disease who require bypass surgery should be advised by their physician to undergo a preoperative examination and evaluation, and to follow the physician’s advice in choosing the most appropriate surgical procedure.
