Ventricular Contractility and Compliance Measured During Axial Flow Blood Pump Support: In Vitro Study

End-systolic elastance and end-diastolic compliance have been used to quantify systolic and diastolic function of the left ventricle (LV). In this study, the effective end-systolic elastance, (EES)eff, end-systolic volume intercept, (V0)eff, and end-diastolic compliance of the LV were assessed at various levels of left ventricular assist device (LVAD) support.
