Hydrodynamic ex-vivo analysis of valve sparing techniques: assessment and comparison

This work investigates the impact of the valve-sparing technique on the aortic valve function. The hydrodynamic performance assessment of each implant was conducted in-vitro on a hydro-mechanical pulse duplicator. This shows that, despite providing generally good performance, current valve sparing techniques are still suboptimal and far from matching the physiological leaflets dynamics.
