Triple branch lesions are lesions of the three main vessels of the coronary arteries. The blood vessels that supply oxygen and nutrients to the heart are called coronary arteries, which emanate from the left and right sinuses of the aorta at the site of the ascending aorta and include the left and right coronary arteries. The coronary arteries are divided into a number of branches in the course of walking, of which the anterior descending branch of the left coronary artery, the rotary branch of the left coronary artery and the right coronary artery, are the main branches of the coronary arteries. The so-called “three-branch lesion” in cardiology is a very serious coronary heart disease in which these three major branches are severely narrowed or even occluded at the same time. Coronary artery disease patients with serious lesions of the three branches of the blood vessels, such as the number of stents required for interventional therapy is relatively large, the long-term effect is not as good as surgical procedures, and therefore it is recommended that the first choice of surgical bypass grafting surgery, that is, coronary artery bypass grafting. However, surgical bypass surgery requires general anesthesia to open the chest and take suitable blood vessels from the body for transplantation, such as the internal thoracic artery, saphenous vein, radial artery, etc. The operation time is relatively long, and the recovery after the operation is relatively slow. It is recommended that the patient go to the cardiology department of the hospital and follow the doctor’s instructions for treatment.
