According to the American Heart Association, 1,025,000 angioplasties were performed in the United States in 2000; of these, 561,000 were balloon angioplasties. There were 655,000 men and 370,000 women who had angioplasties in 2000. Stent placement...
is part of more than 70% of interventional procedures.

A physician describes how the heart works and two specific diseases of the heart, namely congestive heart failure and aortic aneurysms.
During coronary stenting, a catheter is fed into the femoral artery of the upper leg (A). The catheter is fed up to coronary arteries to an area of blockage (B). A dye is released, allowing visualization of the blockage (C). A stent is placed on the balloon-tipped catheter. The balloon is inflated, opening the artery (D). The stent holds the artery open after the catheter is removed (E). (Illustration by GGS Inc.)

Definition
A coronary stent is an artificial support device used in the coronary artery to keep the vessel open.
Description
Coronary stenting usually follows balloon angioplasty, which requires inserting a balloon catheter into the femoral artery in the upper thigh. When this catheter is positioned at the location of the blockage in the coronary artery, it is slowly inflated to widen that artery, and is then removed. The stent catheter is then threaded into the artery and the stent is placed around a deflated balloon. When this is correctly positioned in the coronary artery, the balloon is inflated, expanding the stent against the walls of the coronary artery. The balloon catheter is removed, leaving the stent in place to hold the coronary artery open. A cardiac angiography will follow to insure that the stent is keeping the artery open.
