In stent restenosis remains a clinically relevant problem

摘要

Percutaneous coronary intervention (PCI) is an effective technique for coronary revascularization but is sometimes limited by restenosis and stent thrombosis. Optimal management of in-stent restenosis (ISR) remains inadequately defined. Prior to the introduction of drug eluting stents, brachytherapy was often used to limit recurrent ISR. In this issue of Catheterization and Cardiovascular Interventions, Jensen et al. present a retrospective cohort study of 270 patients with 302 lesions treated with drug-eluting stents (DES) for clinically driven ISR within 12 months after index PCI with either bare-metal stent (BMS) or DES in the population based Western Denmark Heart Registry [1].
