restenosis
Quick Summary
Restenosis is the reoccurrence of stenosis, or narrowing, in a blood vessel or heart valve after it has been treated. This condition can arise after procedures like angioplasty, which is used to open blocked blood vessels, often by inflating a balloon to flatten plaques against the artery wall. While angioplasty is a less invasive alternative to surgery for conditions like coronary heart disease, there is a risk of restenosis because plaques can build up again. Drug-eluting stents are sometimes used in conjunction with angioplasty to help prevent the scar tissue growth that can lead to restenosis.12
