• defined as SW/(LVEDV – k × LVEDV+(1-k) × LV mass (LVM)/1.05)], with k defined by the ratio of epicardial shell volumes corresponding to the volume-axis intercept and baseline LVEDV, calculated as k=[0.0004 × LVM]+0.6408, with Vw presenting volume within the epicardial shell [Vw =k × (LVEDV+LVM/1.05) – LVM/1.05]
