Stent-in-Stent Technique for the Treatment of Proximal Bronchial Restenosis after Insertion of Metallic Stents: A Report of Two Cases

Case Reports in Pulmonology, 2016
Endoscopic treatment of a bronchial restenosis previously treated by insertion of a partially covered self-expandable metallic stent (SEMS) can be difficult.

Calcified Plaque Detachment: Alternative Calcified Plaque Modification After Coronary Intravascular Lithotripsy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified plaque (CP) detachment (CD) and calcium fracture (CF) can occur following coronary intravascular lithotripsy (IVL). The extent to which CF alone facilitates stent expansion during CP modification with IVL remains unclear. Aims This study aimed to investigate the clinical implications of IVL‐induced CD.

A Smart Stent for Monitoring Eventual Restenosis: Computational Fluid Dynamic and Finite Element Analysis in Descending Thoracic Aorta

Machines, 2020
Even though scientific studies of smart stents are extensive, current smart stents focus on pressure sensors. This paper presents a novel implantable biocompatible smart stent for monitoring eventual restenosis.

Evaluation of Treatment Response of Calcified Nodules and Nodular Calcified Lesions Using Mean Density on Coronary Computed Tomography Angiography

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified nodules (CN) and nodular calcifications (NC) present significant challenges during percutaneous coronary intervention (PCI) because of their protruding morphology and high rigidity, which often result in inadequate stent expansion and suboptimal procedural outcomes.

Coating stent materials with polyhedral oligomeric silsesquioxane-poly(carbonateurea)urethane nanocomposites [PDF]

, 2009
The long-term efficacy of coronary or peripheral stenting is limited by in-stent restenosis (ISR), which occurs in 15 to 30% of patients and is attributed primarily to neointimal hyperplasia.

PROSPECTS FOR THE USE OF BIOMARKERS (ADIPONECTIN, P-SELECTIN, INTEGRIN Ββ3) AS BIOCHEMICAL PREDICTORS OF RESTENOSIS IN PATIENTS WITH ISCHEMIC HEART DISEASE AFTER CORONARY STENTING

Žurnal Grodnenskogo Gosudarstvennogo Medicinskogo Universiteta, 2018
Aim.To analyze the literature data about the role of adiponectin, P-selectin and integrin β3 in the pathogenesis of the development of in-stent restenosis in patients with coronary heart disease after coronary stenting, as well as the possibility of ...

Final 2‐Year Results of the REFORM Study: A Randomized Trial of Biolimus DCB Versus Paclitaxel DCB for In‐Stent Restenosis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In the REFORM trial, treatment of coronary in‐stent restenosis with a Biolimus A9™ drug‐coated balloon (BCB) was found to be inferior with respect to in‐segment percentage stenosis at 6‐months in comparison to treatment with a standard paclitaxel coated paclitaxel‐coated balloon (PCB). Aims In this manuscript, the final prespecified

Buddy Wire–Augmented Intravascular Lithotripsy in Refractory Calcified Coronary Lesions: A Five‐Case Series

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Heavily calcified coronary lesions remain a major challenge in percutaneous coronary intervention (PCI), often limiting the effectiveness of intravascular lithotripsy (IVL). We report a five‐case series in which IVL failed to achieve adequate lesion modification but was successfully augmented by the addition of one or more buddy wires.
