Case –Control Study of 3D Morphology in Isolated Mesenteric Artery Dissection
ConclusionUsing an original 3D semi-automated analysis, this study shows that IMAD induces significant morphological changes compared to control individuals: a larger aortomesenteric 3D angle, an increased overall volume and area. IMAD patients with acute mesenteric ischemia presented with a more severe morphological profile. (Source: Cardiovascular Engineering and Technology)

Spiral Laminar Flow is Associated with a Reduction in Disturbed Shear in Patient-Specific Models of an Arteriovenous Fistula
ConclusionThese findings are in agreement with previous clinical studies and further highlight the clinical potential of SLF as a prognostic marker for a healthy AVF, as its presence correlates with an overall reduction in exposure to disturbed shear and a decrease in the incidence of AVF dysfunction, albeit in a small sample size.

Particle Image Velocimetry to Evaluate Pulse Wave Velocity in Aorta Phantom with the lnD –U Method
ConclusionThe PIV technique PWV measurement showed good agreement with the direct tensile test method with a 5.6% difference in Young ’s modulus. Considering the uncertainties from the two methods, the measured elasticities are consistent and close to a 50–60 years old male aortic behavior. The choice of silicone for the phantom material is a relevant and promising option to mimic the human aorta onin vitro systems. (Source: Cardiovascular Engineering and Technology)

Investigating the Equivalent Plastic Strain in a Variable Ring Length and Strut Width Thin-Strut Bioresorbable Scaffold
ConclusionTherefore, the narrow strut designs investigated herein, are likely to offer optimal performance and potentially better patient outcomes. Further work should address the material modelling of next generation polymeric BRS to more accurately capture their mechanical behaviour. Observation of thein-vitro testing indicates that the ArterioSorb\(^{\rm{{TM}}}\) BRS can tolerate greater levels of over expansion than anticipated.

Differences Between Ruptured Aneurysms With and Without Blebs: Mechanistic Implications
ConclusionAneurysms at different locations are likely to develop into varying morphologies and thus be exposed to diverse flow conditions that may predispose them to follow distinct pathways towards rupture with or without bleb development. This could explain the diverse rupture rates and bleb presence in aneurysms at different locations. (Source: Cardiovascular Engineering and Technology)
