Anterior LVAD outflow reduced aortic flow disturbance in models; leaves open whether geometry affects clinical outcomes.
Does an anterior LVAD cannula outflow geometry improve hemodynamics in the ascending aorta compared to a lateral geometry in patient-specific computational models?
Computational fluid dynamics simulations suggest that an anterior LVAD cannula outflow position provides more ordered flow patterns and reduced wall shear stress compared to a lateral position.
Karmonik et al. (2012) studied this question.
