Bare metal stent Bioresorbable vascular scaffold Drug-eluting stent In-stent restenosis Left anterior descending Optical coherence tomography Percutaneous coronary intervention Bioresorbable vascular scaffolds (BVS) demonstrate favourable outcomes in patients with We present the first case of in-stent restenosis (ISR) successfully treated with an everolimus-eluting BVS (ABSORB; Abbott Vascular, Santa He had undergone PCI of the proximal left anterior descending everolimus... Prospective studies of BVS showed favourable outcomes in simple, de novo However, these studies specifically excluded ISR lesions... characterized by late lumen enlargement and replacement of the platform by proteoglycans, resulting in filling of the micro-aneurysms and exclusion of the nidus BVS are a promising addition to the PCI arsenal in managing complex coronary lesions... This case report demonstrates novel use of this technology to treat an ISR lesion of DES characterized by late acquired malapposition.

Baseline Angiogram and Optical Coherence Tomography(A) Baseline angiogram showing a severe restenotic lesion of the proximal leftanterior descending artery with 2 micro-aneurysms (asterisk), with contraststaining outside the previously implanted drug-eluting stent suggestinglate-acquired malapposition secondary to hypersensitivity vasculitis. (B) Opticalcoherence tomography performed after initial thrombectomy and balloon dilatationangioplasty showing typical late acquired malapposition features with “sunflower”appearance (top right panel) and 2 small pockets representing micro-aneurysms(asterisk; lower panel).

Mentions: The coronary angiogram showed a severe 95% ISR lesion of the proximal LAD with thrombusand multiple areas of contrast staining outside the stent contour, compatible withcoronary micro-aneurysms (Figure 1A).Thromboaspiration revealed white thrombus. Optical coherence tomography (OCT) wascompatible with a localized hypersensitivity reaction to first-generation DES (Figure 1B). After consensus with the referringphysician, an ABSORB everolimus-eluting BVS 3.0 x 18 mm was deployed (Figure 2A). Repeated OCT showed good scaffoldapposition and coverage of the micro-aneurysms (Figure2B). The patient was discharged the following day on dual antiplatelet therapywith aspirin and ticagrelor. The patient was asymptomatic at 6 months clinicalfollow-up.
