Death is very rare (1%) as a result of the stent placement procedure.
Sometimes a blockage returns to the treated coronary artery (restenosis). If restenosis occurs, it usually happens within the first six months after the procedure. If the patient...
has previously experienced restenosis, there is an increased risk that it will recur. Repeat blockages can be treated with other interventional procedures; coronary artery bypass graft surgery may be needed.
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.
How many open-heart surgeries are performed each year? In 2005 in the United States, these procedures were performed: Valve replacements 106,000 Bypass (cardiac revascularization) 469,000 Heart transplants (performed in 2006) 2,192 Total open-heart procedures 699,000.
