In vitro biomechanical and hydrodynamic characterisation of decellularised human pulmonary and aortic roots

The use of decellularised biological heart valves in the replacement of damaged heart valves ... ...The purpose of this study was to assess the effect of low concentration sodium dodecyl sulphate decellularisation on the in vitro biomechanical and hydrodynamic properties of cryopreserved human aortic and pulmonary roots.... ... performance of the valve roots. A viscoelastic impedance adapter (VIA; Vivitro System Inc., Victoria BC, Canada) was used to deliver a more physiological ventricle pressure and flow waveform in the simulator. This system allowed for ...
