Cardiac bypass surgery, also known as coronary artery bypass grafting, is performed only when arteriography, CT angiography, and other tests indicate the existence of indications for the surgery.
In cases of coronary artery disease and other cardiac arterial anomalies, timely surgery is required if there is a stenosis of more than 70% of the proximal lumen of one or more of the three main coronary arteries with a distal vessel diameter of more than 1.0mm, or if there is a stenosis of more than 50% in the lumens of three coronary arteries or in the lumen of the main trunk of the left coronary artery.
In addition to the above, whether the patient is physically able to tolerate the surgery and whether there are contraindications to surgery such as systemic infections should also be taken into consideration. Meanwhile, there are currently interventional procedures in addition to coronary artery bypass grafting to treat the above conditions, so it is not always necessary to carry out cardiac bypass grafting immediately when there are indications of the above.
It is recommended to go to the hospital in time if the above test results occur.
