Interventional treatment of coronary heart disease is also called coronary angioplasty in clinic, which includes percutaneous balloon angioplasty of coronary artery, coronary stent implantation or coronary artery plaque blood membrane surgery, coronary artery thrombus aspiration and so on. This technique is mainly used to treat coronary artery stenosis or thrombosis in coronary artery. After interventional treatment, coronary artery stenosis can be relieved and myocardial ischemia can be improved. Generally, we will pass the radial artery through the wrist, or the femoral artery at the thigh, and send the catheter guide wire of this angiography through the direction of the vascular alignment to the opening of the coronary artery. Generally, we will carry out the coronary artery angiography first to determine the extent of coronary artery disease, and then decide whether to need intervention treatment. If interventional treatment is needed, generally speaking, this angiogram will be followed by this treatment. The stenosis of the coronary artery will be expanded first through the balloon, and then the stent will be implanted. Now there are also drug balloons. After ordinary balloon dilation, the drug balloon will be used to expand the lesion. The drug is placed at this part of the coronary lesion, and then the elastic retraction and restenosis of the coronary lesion will be prevented.
