Promising in vitro hemodynamics for novel three-leaflet valves; leaves open translation to in vivo durability or clinical outcomes.
In vitro flow analysis of a novel three-leaflet mechanical heart valve demonstrates favorable hemodynamics, including smooth closure and effective sinus wash-out.
Brücker et al. (2002) studied this question. New mechanical heart valve prosthesis with three leaflets was evaluated on Flow characteristics (pulsatile flow, velocity field, occluder motion). A new three-leaflet mechanical heart valve prosthesis demonstrated a well-defined core flow, desired wash-out effect in the aortic sinuses, and smooth closure with reduced impact velocity in vitro.
