Stent Failure in Contemporary Practice.

Despite advances in stent platform technologies and procedural techniques, stent failure remains a critical clinical consideration, accounting for approximately 10% of invasive coronary procedures. Various mechanisms underlying stent failure can now be readily identified using intracoronary imaging modalities, including neointimal hyperplasia and neoatherosclerosis, stent thrombosis, stent fracture, and stent recoil. This review provides an overview of these etiologies in contemporary practice.
