Optical coherence tomographic analysis of in-stent neoatherosclerosis after drug-eluting stent implantation.
BACKGROUND We report findings from optical coherence tomography (OCT) of in-stent neoatherosclerosis as a cause of drug-eluting stent (DES) failure. METHODS AND RESULTS Optical coherence tomography and grayscale and virtual histology intravascular ultrasound were performed in 50 patients (30 stable, 20 unstable angina) with 50 DES in-stent restenosis lesions and intimal hyperplasia >50% of st...
متن کاملOverview of Intracoronary Brachytherapy for in-Stent Restenosis of a Drug-Eluting Stent
Percutaneous coronary intervention with stenting is considered recently as the most common procedure for the treatment of symptomatic coronary. The article reviewed 41 studies published during 1997-2019 on intracoronary brachytherapy for in-stent restenosis of a drug-eluting stent. Intracoronary radiation therapy was finally confirmed in the setting of in-stent restenosis using as adjunctive th...
متن کاملOptical coherence tomographic observation of in-stent neoatherosclerosis in lesions with more than 50% neointimal area stenosis after second-generation drug-eluting stent implantation.
BACKGROUND Despite the enhanced properties of the second-generation drug-eluting stent (DES), its association with neoatherosclerosis has not been sufficiently evaluated. Therefore, we sought to evaluate and compare neoatherosclerosis in second-generation DESs to first-generation DESs. METHODS AND RESULTS A total of 212 DES-treated patients with >50% percent neointimal cross-sectional area st...
متن کاملNeoatherosclerosis after Drug-Eluting Stent Implantation: Roles and Mechanisms
In-stent neoatherosclerosis (NA), characterized by a relatively thin fibrous cap and large volume of yellow-lipid accumulation after drug-eluting stents (DES) implantation, has attracted much attention owing to its close relationship with late complications, such as revascularization and late stent thrombosis (ST). Accumulating evidence has demonstrated that more than one-third of patients with...
متن کاملAssociation of Localized Hypersensitivity and In-Stent Neoatherosclerosis with the Very Late Drug-Eluting Stent Thrombosis
BACKGROUND Localized hypersensitivity reaction, delayed arterial healing, and neoatherosclerosis inside the stent have been suggested as the underlying pathologic mechanisms of very late stent thrombosis (VLST) of drug-eluting stent (DES). The present study sought to explore the prevalence of inflammatory cell infiltrates and evidence for fragments of atherosclerotic plaques in the aspirated th...
