There are two kinds of heart bypass surgery, one is beating heart bypass surgery. One is bypass surgery for cardiac arrest.

As the name implies, bypass surgery is to take the patient's own blood vessels (such as internal thoracic artery, great saphenous vein of lower limbs, etc.). ) or vascular substitutes connect the distal end of the narrow coronary artery with the aorta, so that the blood bypasses the narrow part and reaches the ischemic part, improving the blood supply to the myocardium, thereby achieving the purposes of relieving angina symptoms, improving cardiac function, improving the quality of life of patients and prolonging life.

This operation is called coronary artery bypass grafting, which establishes a smooth path between the aortic root filled with arterial blood and ischemic myocardium.

So some people call it a "bridge" in the mind, commonly known as "bridge".
