Trileaflet semilunar valve reconstruction: pulsatile in vitro evaluation

We investigated a new surgical technique of trileaflet semilunar valve reconstruction possessing the potential of remaining sufficient and allowing for some growth with the child. Pulsatile flow was produced by a Series piston pump (SuperPump AR; ViVitro Labs, Victoria, Canada), connected to the ventricular chamber. TSVR was achievable in vitro. Hydrodynamic pressure and echocardiographic evaluations demonstrated a sufficient and non-stenotic neo-valve.
