Key result
The 25 mm Carpentier-Edwards PERIMOUNT Magna Ease prosthesis created a wider, more homogenous flow with significantly lower peak velocities (2.47±0.15 m/s) compared to the 21 and 23 mm sizes.
Why the study?
Does the size of the Carpentier-Edwards PERIMOUNT Magna Ease prosthesis affect fluid dynamical performance in an in vitro model?
Does the size of the Carpentier-Edwards PERIMOUNT Magna Ease prosthesis affect fluid dynamical performance in an in vitro model?
Larger (25 mm) Carpentier-Edwards PERIMOUNT Magna Ease prostheses create a wider, more homogenous flow with lower peak velocities compared to smaller sizes in vitro.

In vitro flow data on PERIMOUNT Magna Ease should not alter valve selection; leaves open need for in vivo hemodynamic validation.
Marx et al. (2018) studied this question. Carpentier-Edwards PERIMOUNT Magna Ease prosthesis (25 mm) vs. 21 and 23 mm sizes was evaluated on Fluid dynamical performance (maximal velocity, strain, velocity gradient). The 25 mm Carpentier-Edwards PERIMOUNT Magna Ease prosthesis created a wider, more homogenous flow with significantly lower peak velocities (2.47±0.15 m/s) compared to the 21 and 23 mm sizes.
