Simulation of bifurcated stent grafts to treat abdominal aortic aneurysms (AAA) [PDF]

, 2016
In this paper a method is introduced, to visualize bifurcated stent grafts in CT-Data. The aim is to improve therapy planning for minimal invasive treatment of abdominal aortic aneurysms (AAA). Due to precise measurement of the abdominal aortic aneurysm and exact simulation of the bifurcated stent graft, physicians are supported in choosing a suitable ...

The future of drug-eluting stents

Pharmacological Research, 2008
This review aims to provide a glimpse into the future of drug-eluting stents (DES). Since their arrival in 2002, DES have transformed the practice of interventional cardiology by drastically reducing restenosis and the need for repeat revascularization.

Prediction of stent under-expansion in calcified coronary arteries using machine-learning on intravascular optical coherence tomography [PDF]

arXiv, 2022
BACKGROUND Careful evaluation of the risk of stent under-expansions before the intervention will aid treatment planning, including the application of a pre-stent plaque modification strategy. OBJECTIVES It remains challenging to achieve a proper stent expansion in the presence of severely calcified coronary lesions.

In Silico Fatigue Optimization of TAVR Stent Designs with Physiological Motion in a Beating Heart Model [PDF]

arXiv, 2023
The rapid expansion of TAVR to younger, low-risk patients raises concerns regarding device durability. Necessarily, extended stent lifetime will become more critical for new generation devices. In vitro methods commonly used for TAVR stent fatigue testing exclude the effects of the beating heart.

Is a Drug-Eluting Stent the Default Treatment Strategy for Drug-Eluting Stent Restenosis?∗

Journal of the American College of Cardiology, 2015
In 2001, when Morice et al. [(1)][1] presented the initial results of RAVEL (The Randomized Study With the Sirolimus-Coated Bx Velocity Balloon-Expandable Stent in the Treatment of Patients With De Novo Native Coronary Artery Lesions), showing 0% angiographic restenosis 6 months after ...

Does the use of paclitaxel or rapamycin-eluting stent decrease further need for coronary-artery bypass grafting when compared with bare-metal stent?

São Paulo Medical Journal
CONTEXT AND OBJECTIVE: The safety and efficacy of drug-eluting stents reduce the need for surgical revascularization. The objective of the present study was to investigate whether paclitaxel or rapamycin-eluting stent are effective in avoiding the need ...

Very Late Stent Thrombosis 42 Months after Implantation of Sirolimus-Eluting Stent and Discontinuation of Antiplatelet Therapy

Case Reports in Medicine, 2009
Although safety profiles of sirolimus-eluting stents do not seem to differ in short-to-medium term from those of bare-metal stents, late stent thrombosis after deployment of drug-eluting stents has emerged as a potential safety concern in the era of high-

Relationship Between Intravascular Ultrasound Guidance and Clinical Outcomes After Drug-Eluting Stents: Two-Year Follow-Up of the ADAPT-DES Study

Circulation. Cardiovascular Interventions, 2018
Background: In the large-scale ADAPT-DES study (Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents), drug-eluting stent implantation with intravascular ultrasound (IVUS) guidance was associated with a reduction in 1-year rates of stent ...

Nanostructured 316L Stainless Steel Stent Surfaces Improve Corrosion Resistance, and Enhance Endothelization and Hemocompatibility

Advanced Materials Interfaces, EarlyView.
This study investigates the impact of nanostructured surface modification on corrosion resistance, HUVEC functions, and platelet interactions of 316L SS for cardiovascular stents. Nanostructured surfaces enhanced HUVEC proliferation, migration, and angiogenesis‐related gene expression while reducing platelet adhesion and hemolysis.
