Before coronary angioplasty is done, a Doctor tries to know which arteries are clogged, how many of them are blocked, and what is the severity of the blockages. For this purpose, an Angiography test is done. The X-Ray picture will show any blockages, how many, and where they’re located. Once your doctor gets this information, the angioplasty can proceed. Your doctor will blow up the balloon in the blockage and push the blockage outward against the artery wall. this opens the artery more and enhances blood flow.
After the artery is widened, a small mesh tube called a Stent generally made of metal is kept inside the artery to keep it widened. Some stents are coated with medicines that are continuously and slowly released into the artery. These medicines help prevent the artery from becoming blocked again. After the angioplasty is completed, the patient is in ICU for the next 24 hours and then discharged.
