Biohybrid Vascular Graft Made of Textile‐Reinforced Elastin‐Like Recombinamers and Its Preservation via Drying Processes

Advanced Healthcare Materials, EarlyView.
Clinical translation of biohybrid medical implants requires the previous implementation of drying schemes that can facilitate their sterilization and storage. This study addresses that critical aspect and elucidates the impact of drying on biohybrid vascular grafts, highlighting the need for implant‐specific drying strategies to ensure safety ...

Effects of stenotic aortic valve on the left heart hemodynamics: a fluid-structure-electrophysiology approach [PDF]

arXiv, 2021
The aortic valve is a three-leaflet passive structure that, driven by pressure differences between the left ventricle and the aorta, opens and closes during the heartbeat to ensure the correct stream direction and flow rate. In elderly individuals or because of particular pathologies, the valve leaflets can stiffen thus impairing the valve functioning ...
