Stent expansion in curved vessel and their interactions: a finite element analysis.
TLDR
A finite element method to study the expansion of a stent in a curved vessel and their interactions and results show that in the CV model, the vessel was straightened by stenting and a hinge effect can be observed at extremes of the stent.About:

On the effects of different strategies in modelling balloon-expandable stenting by means of finite element method.
Francesca Gervaso,Claudio Capelli,Lorenza Petrini,Simone Lattanzio,Luca Di Virgilio,Francesco Migliavacca +5 more
TL;DR: The finite element method is applied to simulate three different approaches to evaluate stent-free expansion and stent expansion inside an artery, showing differences in the free and confined-stent expansions due to different expansion techniques.

A novel simulation strategy for stent insertion and deployment in curved coronary bifurcations: comparison of three drug-eluting stents.
Peter Mortier,Gerhard Holzapfel,Gerhard Holzapfel,Matthieu De Beule,Denis Van Loo,Yves Taeymans,Patrick Segers,Pascal Verdonck,Benedict Verhegghe +8 more
TL;DR: This study investigates and compares three different second generation DESs when being implanted in the curved main branch of a coronary bifurcation with the aim of providing better insights into the related changes of the mechanical environment.

TL;DR: The method presented in this paper can be used to predict stresses in the stent struts and the vessel wall, and thus evaluate whether a specific stent design is optimal for a specific patient.

Simulation of a balloon expandable stent in a realistic coronary artery—Determination of the optimum modelling strategy
TL;DR: Direct application of pressure to the stent inner surface may be used as an optimal modelling strategy to estimate the stresses in the vessel wall using these restraining elements and hence offer a very efficient alternative approach to numerically modelling stent deployment within complex arterial geometries.

Modelling of the provisional side-branch stenting approach for the treatment of atherosclerotic coronary bifurcations: effects of stent positioning.
Dario Gastaldi,Stefano Morlacchi,Roberto Nichetti,Claudio Capelli,Gabriele Dubini,Lorenza Petrini,Francesco Migliavacca +6 more
TL;DR: Results confirm that the re-establishment of an optimal spatial configuration of the stent after the PSB approach is achieved with both strategies and show that case of stent positioning with one cell placed centrally should be preferred, avoiding the presence of struts inside the vessel lumen, which may reduce hemodynamic disturbances.

Patterns and Mechanisms of In-Stent Restenosis A Serial Intravascular Ultrasound Study

TL;DR: Late lumen loss and in-stent restenosis were the result of neointimal tissue proliferation, which tended to be uniformly distributed over the length of the stent.

Pathological Mechanisms of Fatal Late Coronary Stent Thrombosis in Humans
TL;DR: Stenting across branch ostia, disruption of adjacent vulnerable plaques, radiation therapy, and extensive plaque prolapse can precipitate late stent thrombosis, a potentially fatal complication of coronary stenting.

Cardiovascular stent design and vessel stresses: a finite element analysis.
TL;DR: An analysis of the arterial wall stresses in the stented arteries indicates that the modular S7 stent design causes lower stress to an atherosclerotic vessel with a localized stenotic lesion compared to the slotted tube NIR design.

TL;DR: Paclitaxel-eluting stent implantation is considered safe and potentially efficacious in the treatment of ISR and IVUS guidance to ensure good stent deployment with complete coverage of target lesion may reduce reintervention.

Non-Newtonian blood flow in human right coronary arteries: Transient simulations
TL;DR: This study looks at pulsatile blood flow through four different right coronary arteries, which have been reconstructed from biplane angiograms, and shows that the use of a Newtonian blood model is a reasonably good approximation, but to study the flow within the artery in greater detail, a non-Newtonian model is more appropriate.
