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

open access: yes, 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 ...

Successful Management of a Rare Case of Stent Fracture and Subsequent Migration of the Fractured Stent Segment Into the Ascending Aorta in In-Stent Restenotic Lesions of a Saphenous Vein Graft [PDF]

open access: yes, 2012
Stent fracture is a complication following implantation of drug eluting stents and is recognized as one of the risk factors for in-stent restenosis.

The future of drug-eluting stents

open access: yesPharmacological 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.

Rhombic-Shaped Channel Stent with Enhanced Drug Capacity and Fatigue Life

open access: yesMicromachines, 2017
A drug-eluting stent with rhombic-shaped drug reservoirs is proposed, aimed at providing long-term drug delivery and enhanced fatigue life. Unique rhombic-shaped reservoirs or channels on the stent struts can increase the total drug capacity and improve ...

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

open access: yesarXiv, 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.

Comparison of Long‐Term Clinical Outcomes of Lesions Exhibiting Focal and Segmental Peri‐Stent Contrast Staining

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundPeri‐stent contrast staining (PSS) after metallic drug‐eluting stent deployment is associated with target lesion revascularization and very late stent thrombosis.

Drug-Coated Balloon vs. Drug-Eluting Stent in Acute Myocardial Infarction: A Systematic Review and Updated Meta-Analysis

open access: yesAnatolian Journal of Cardiology, 2023
Background: This study aimed to systematically review the evidence of drug-coated balloon used in the treatment of acute myocardial infarction and compared with using drug-eluting stent in terms of clinical and angiographic outcomes for a relatively long

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

open access: yesarXiv, 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.

Drug Distribution and Stent Retention of Drug Eluting Stents [PDF]

open access: yes, 2008
In this paper the examinations of drug eluting coronary stents are shown, such as the morphology of the coatings before expansion, drug distribution, the methodology and the value of stent retention.

Design and testing of hydrophobic core/hydrophilic shell nano/micro particles for drug-eluting stent coating [PDF]

open access: yes, 2018
In this study, we designed a novel drug-eluting coating for vascular implants consisting of a core coating of the anti-proliferative drug docetaxel (DTX) and a shell coating of the platelet glycoprotein IIb/IIIa receptor monoclonal antibody SZ-21.
