Computed tomography based assessment of programmable shunt valve settings

Brain and Spine, 2021
Introduction: Programmable shunt valve settings can sometimes be difficult to assess using classic read-out tools, warranting a skull X-ray. Research question: Can we use available head computed tomography (CT) scans to determine the valve settings, in ...

Bioactive 3D-Printed valve scaffold promoting valvular regeneration via immunomodulation and endothelialization [PDF]

Bioactive Materials
The in vivo performance of tissue-engineered heart valves remains constrained by a persistent early failure triad at the blood-material interface, namely thrombosis, unresolved inflammation, and slow endothelialization.
