A novel drawbridge-shaped bileaflet mechanical valve utilizes vortex flow in the sinus of Valsalva to initiate closure 41 ms earlier than a conventional valve in an in vitro model, potentially reducing backflow and mechanical stress.

May reduce regurgitation risk in mechanical valves; leaves open whether vortex-assisted designs improve outcomes, pending in vivo trials.
Ohta et al. (2000) studied this question.
