A coronary stent implant is a therapeutic cardiac procedure that involves placing a stent, which is a small mesh-like wire tube in a narrowed artery.
This procedure is similar to angioplasty in many ways. However, the stent is left permanently in place in the artery to act as a scaffold to help keep the artery open. Usually, an angioplasty procedure is performed first.
The balloon inflations help open the artery to allow the stent to be placed easily.
The angioplasty catheter is removed.
A different angioplasty catheter with a stent crimped on the balloon is advanced into the artery and carefully positioned at the blockage.
The angioplasty balloon is inflated which opens the stent and presses it into the artery wall. The stent holds the artery open and helps reduce the rate of restenosis (a recurrence of the narrowing within the artery).
