What is In-Stent Restenosis?
In-stent restenosis is the overgrowth of tissue within a stent that causes a significant blockage in the artery that requires a procedure to re-open the narrowing in the artery. This re-narrowing of the stent occurs due to a response by the artery to “heal” the stented area, and this usually occurs within 3-9 months after the stent is placed.
