Abstract

A membrane theory model of the infarcted left ventricle is described which represents the pressure-volume relation of the ventricle in diastole and end-systole, states in which the contraction velocity is zero. This membrane theory model is shown to give essentially the same diastolic pressure-volume relation as a more elaborate model which fully accounts for variations through the wall thickness. The end-systolic pressure-volume relation of an infarcted ventricle is obtained by means of a specially tailored finite element method, which is described in detail. From the end-systolic and diastolic pressure-volume relations the effect of infarction on the pumping performance of the ventricle can be determined. Representative numerical results are presented.

    Various mathematical and numerical investigations for modeling of LV myocardium have been done to describe myocardial behavior (not flow) under infarction conditions (such as [11–15]). In [16–18] an initially spherical membrane model with finite element method (FEM) had been used to model infarcted LV. The aim of those studies was to investigate pressure-volume relations in normal and infarcted LV cases; obviously, no flow analyses have been carried out.
