A coronary stent is an artificial support device placed in the coronary artery to keep the vessel open after treatment for coronary artery disease. Also called atherosclerosis, coronary artery disease is a build-up of fatty matter and debris on the...
walls of the arteries. Over time, this buildup narrows the arteries and reduces blood supply to the heart.
The stent is usually a stainless steel mesh tube that is available in various sizes to match the size of the artery and hold it open after the blockage in the artery has been treated.
A physician describes how the heart works and two specific diseases of the heart, namely congestive heart failure and aortic aneurysms.
A coronary stent is an artificial support device used in the coronary artery to keep the vessel open.
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.
In 2006, 2,192 heart transplantations were performed in the United States. There are 257 transplant hospitals in the United States, 135 of which perform heart transplantations. (http://www.unos.org/)
