Coronary stent is a small expandable wire tube. Cardiovascular diseases can lead to partial or total blockage of coronary arteries. The most common kind of stent is made of metal.
A sizeable proportion of patients who undergo successful coronary artery stent implantation experiences chest pain immediately after the procedure andor in the following months in the absence of in-stent restenosis. Consequently angioplasty is performed to prevent the fatal consequences of a decrease in blood supply to. A balloon catheter is pushed over the guide wire and into the blockage.

Here you can see the artery in the middle of the image with blood flow reestablished. Stent thrombosis is uncommon after effect of stent placement but have serious complication if it occurs. The stent helps keep the artery open.
A small tube called a balloon catheter is inserted into the femoral artery leg or the radial artery arm and advanced toward the heart to the very top of the aorta. In general you can expect to return to work and normal activities in as few as three days. Compare to the first image.
