The cost of heart bypass surgery is around$100,000. Heart bypass surgery, also known as coronary artery bypass grafting, involves taking a blood vessel from the root of the aorta to the distal end of the coronary artery stenosis, bypassing the stenotic area and improving myocardial ischemia. The bridge vessel is usually taken from the patient’s own vessels, such as the internal mammary artery and saphenous vein. Coronary artery bypass surgery is an effective treatment for coronary artery disease, which can improve the blood supply to the myocardium and achieve the purpose of relieving angina symptoms, improving the quality of life and prolonging life expectancy. Indications for coronary artery bypass surgery include left main stem lesions; three-branch lesions or diffuse lesions in multiple vessels; lesions in more than two vessels, especially with proximal stenosis of the anterior descending branch. It can also be used for cardiac emergencies, such as failed interventions or patients with acute complications.
