Ellipsoidal geometry may guide artificial valve chamber design to limit shear; leaves open whether in vitro benefits reduce thrombosis or improve durability in vivo.
In an in vitro model of the 'jellyfish' artificial heart valve, an ellipsoidal chamber geometry provided superior shear stress and velocity distribution profiles compared to cylindrical or sinuses of Valsalva models.
Morsi et al. (2000) studied this question.
