Chamber dimensions and function: superior endocardial visualisation and freedom from geometric modelling Left ventricular volume and function The majority of echocardiographic studies are performed to investigate left ventricular (LV) chamber dimensions and LV ejection fraction (LVEF).1 Current methods via two-dimensional (2D) echocardiography (2DE) are operator-dependent, relying on the visual interpretation of moving images, and succumb to inter- and intra-observer variability and poor test–retest reliability.2-4 To calculate a volume, geometric modelling of chamber shape must be performed and consequently, LVEF estimation from 2DE is sub
