Why the study?
Does a natural-like aortic root geometry with three sinuses improve coronary entry-flow and reduce peak pressure compared to straight tube or pseudo-sinus geometries in computational models of a bileaflet mechanical heart valve?

Computational modeling suggests that using a prosthesis with physiologic sinuses during a Bentall procedure may reduce local pressure peaks and leaflet closing velocity without significantly altering coronary entry flow.

May reduce coronary pressure peaks and leaflet velocity in models; leaves open clinical relevance for Bentall prosthesis design.
Tullio et al. (2010) studied this question.
