Interventional treatment of coronary heart disease is a treatment that has made great progress in cardiology in the last 20 years. For example, patients with coronary heart disease can be treated through a minimally invasive method by passing a catheter from the femoral artery at the root of the thigh through the radial artery in the arm, sending the catheter along the entry path of the vessel to the heart vessel and administering drugs to see how much of the vessel supplying the heart is blocked. If the vessel is more severely blocked, the stenosis can be lifted through this pathway, for example, with balloon dilation and stent implantation, and then the problem can be solved. Of course, the interventional treatment for coronary heart disease is not only stenting, but it is much more than that. For example, if some patients have a blockage after stenting, there are now better drug balloons, and even after the blockage is treated, the drug is sent through the balloon to relieve the stenosis problem, and often there is no need to implant a stent again. There are also some patients with small vascular lesions that do not require stent implantation and may have their stenosis relieved by balloon dilation. Other patients have more severe atherosclerosis and very severe calcification. Nowadays, there are advanced methods, such as spinning, which can go in and spin the calcified lesion to release the stenosis, and subsequent patients can also be stented.
