In-stent stenosis remains a major limitation of intracoronary stenting, with rates reaching up to 59% in high-risk lesions compared to 10-20% in selected patients.
O ver 1.5 million percutaneous coronary revascularisation procedures are performed annually world wide, most being intracoronary stenting. Despite enormous advances in devices, the major limitation is in-stent stenosis (ISS) (reviewed by Bennett and O'Sullivan 1 ). Although ISS rates are 10-20% in selected patients, we now stent total occlusions, saphenous vein bypass grafts, both angioplasty and ISS sites, diabetic patients, and small vessels. Thus, real ISS rates are much higher, up to 59% in some high risk lesions.
Martin R. Bennett (Tue,) conducted a review in In-stent stenosis. Intracoronary stenting was evaluated on In-stent stenosis. In-stent stenosis remains a major limitation of intracoronary stenting, with rates reaching up to 59% in high-risk lesions compared to 10-20% in selected patients.
