Bioresorbable vascular scaffold for coronary in-stent restenosis: A novel concept

Abstract

The management of patients with significant in-stent restenosis (ISR) with drug-eluting stent is still not well defined. Various treatment modalities include plain old balloon angioplasty (POBA), metallic stent, cutting or scoring balloon and drug-eluting balloon (DEB). Bioresorbable vascular scaffold (BVS) is the latest technology for the treatment of de novo coronary artery lesions. The use of BVS in ISR is based on the rationale of local drug delivery as achieved by DEB without the permanent bi-layer of metal and also stabilizes dissection flaps and prevents acute recoil as provided by metallic stent. To the best of our knowledge this is the first case report of the use of BVS in patient with ISR.
