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.

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.

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 ...

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.

In-stent Restenosis

Reviews in cardiovascular medicine, 2003
In 1998, 539,000 percutaneous transluminal coronary angioplasty (PTCA) procedures were performed in the United States, an increase of 248% since 1987 [1]. Most of these interventions were followed by stenting. The advent of stents has revolutionized interventional cardiology; however, the Achilles’ heel of stenting is in-stent restenosis (ISR). In this

Caracterización de la restenosis de stents coronarios convencionales y liberadores de medicamentos en pacientes incluidos en el registro DRug Eluting STent (DREST) Characterization of conventional coronary stents restenosis and drug eluting stents in patients included in the Drug Eluting Stent Registry (DREST)

Revista Colombiana de Cardiología, 2012
Introducción y objetivos: los stents convencionales presentan tasas de restenosis intrastent entre 10% y 60%, mientras los stents liberadores de fármacos alcanzan el 10%. Para Latinoamérica, no hay reportes de restenosis intrastent en comparación con los

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.

Timing of silicone stent removal in patients with post-tuberculosis bronchial stenosis

Annals of Thoracic Medicine, 2013
Context: In patients with post-tuberculosis bronchial stenosis (PTBS), the severity of bronchial stenosis affects the restenosis rate after the silicone stent is removed.

Clinical Outcomes of Drug‐Eluting Stents and Drug‐Coated Balloons in Tortuous Small Coronary Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background In small, tortuous coronary lesions, the long‐term comparative performance of drug‐coated balloon (DCB) angioplasty versus drug‐eluting stent (DES) treatment remains uncertain, despite both strategies being widely used in contemporary percutaneous coronary intervention (PCI) practice. Aims This study aimed to compare 3‐year clinical
