Computational fluid dynamic simulations of a novel 3-leaflet mechanical heart valve showed that increasing the inflow diameter up to 38 mm decreased flow velocity from 1543 mm/s to 1475 mm/s.
Computational fluid dynamic simulations of a novel 3-leaflet mechanical heart valve demonstrate that increasing inflow diameter up to 38 mm results in a more homogenous velocity profile and lower flow velocity.

Larger inflow diameters may modestly lower velocities in simulated valves; hypothesis-generating for design optimization pending in vivo validation.
Sievers et al. (2018) studied Mechanical heart valve design. Different anatomical inflow configurations (conical vs cylindrical) vs. Cylindrical configuration was evaluated on Flow velocity and pressure characteristics. Computational fluid dynamic simulations of a novel 3-leaflet mechanical heart valve showed that increasing the inflow diameter up to 38 mm decreased flow velocity from 1543 mm/s to 1475 mm/s.
