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.

An Integrated Visual Analytics System for Studying Clinical Carotid Artery Plaques [PDF]

arXiv, 2023
Carotid artery plaques can cause arterial vascular diseases such as stroke and myocardial infarction, posing a severe threat to human life. However, the current clinical examination mainly relies on a direct assessment by physicians of patients' clinical indicators and medical images, lacking an integrated visualization tool for analyzing the ...

Artesunate Inhibits Neointimal Hyperplasia by Promoting IRF4 Associated Macrophage Polarization

Advanced Science, EarlyView.
This study shows that macrophage interferon regulatory factor 4 (IRF4) improved arterial injury‐induced neointimal hyperplasia by promoting of M2 polarization via up‐regulating krüppel‐like factor 4 (KLF4) in rodent and nonhuman primate models. Notably, artesunate is identified as a potent inducer of IRF4 in macrophages, and proposed as a promising ...

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.

Abstract Number ‐ 168: Conventional angiography versus non‐invasive imaging in the assessment of symptomatic carotid disease

Stroke: Vascular and Interventional Neurology, 2023
Introduction The indication for carotid endarterectomy in symptomatic carotid stenosis of 50% or more was established based on catheter angiography. Yet, in practice, operative referral is still largely based on non‐invasive imaging.

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.

Metal–Organic Frameworks: Unlocking New Frontiers in Cardiovascular Diagnosis and Therapy

Advanced Science, EarlyView.
Metal–organic frameworks (MOFs), are composed of metal ions and bridging organic ligands, are recognized as an excellent platform for host‐gust chemistry. Its rich structural composition, modifiable sites, and multilevel pore distribution can provide delivery and release of signaling molecules, probes, and therapeutic drugs, which exhibit great medical
