Abstract

The occluder motion of bileaflet valves has been studied by researchers in order to understand critical kinematic features that can be associated with post-implant complications. The closing phase, in particular, was studied monodimensionally using different techniques (laser and timing gate) in order to investigate the cavitation potential of valves, but the results these techniques yield are not measurable in vivo. Therefore we analysed the valve closing phase motion by means of High Speed Videography (HSV) on a bileaflet valve model, the 29 mm-sized Sorin Bicarbon. Testing was performed in a standard way using the pulse duplicator developed at the University of Sheffield (UK) with the valve mo
