Heart failure remains a major global burden, and limited donor availability has made left ventricular assist devices (LVADs) a critical alternative. However, most studies of left ventricular (LV) flow under LVAD support rely on single cases or small cohorts, contributing to large variability in inflow cannula designs and limiting population-level understanding of how LV morphology influences haemodynamics. This study addresses this gap using a parametrised statistical shape model (SSM) of the LV
