The performance of the cardiovascular system depends on the interaction between the left ventricle and the arterial tree. Functional analysis of this interaction requires that the left ventricle and the arterial system be described in similar terms. Effective arterial elastance (Ea) characterizes the functional properties of the arterial system and ventricular end-systolic elastance (Ees) characterizes the ventricular systolic function. The efficiency of energy transfers between the left ventricle and the arterial system strongly depends on Ees/Ea ratio. The aim of this paper is to show the interest of collaboration between cardiologists and engineers, to elaborate new original techniques to assess ventriculo-arterial coupling in critically ill patient and guide hemodynamic therapy.
