Cardiac stent implantation surgery belongs to class IV surgery, which can be considered as a larger surgery, but the current procedure is mainly minimally invasive interventional surgery, which is less traumatic after surgery. Cardiac stent implantation is now an important clinical treatment for coronary artery stenosis and belongs to Class IV surgery, which can be considered a larger surgery, but the current procedure is mainly minimally invasive interventional surgery, and the surgical procedure mainly includes steps such as puncture, placement of a tube, establishment of a track, and placement of a stent. Most cardiac stenting procedures use local anesthesia to puncture the radial artery and use a guidewire to follow the artery in the arm all the way to the root of the ascending aorta, looking for a stenosis to place the stent using the guidewire in the stenosis to complete the procedure. The procedure is difficult but less invasive, and patients are usually able to get out of bed on their own within a few hours after the procedure is completed. It is important to follow your doctor’s instructions before and after the cardiac stenting procedure.
