Abstract

In this work we use a Finite Element model of the left ventricular
(LV) mechanics to assess the sensitivity of strains to geometry.
Six principal shape modes extracted from an atlas of LV geometries
using principal component analysis, have been used to model the variability
of the geometry of a population of 1991 asymptomatic volunteers.
We observed that shear strains are more sensitive than normal strains to
geometry. For all the strains, shape mode 1, related with variation in size
within the population, plays an major role, but none of the six principal
modes can be considered non influential.
