Estimation of cardiac contractility, left-ventricular relaxation and cardiac output during rotary blood pump support: using the left-ventricular pressure

Objective: Estimators to accurately monitor ventricular relaxation, cardiac contractility and cardiac output (CO) during support of a left ventricular assist device (LVAD), based on the left ventricular pressure (LVP) and pump-intrinsic signals, were developed. The aim was to continuously monitor these cardiac parameters, hereby tracking the...
