Absolute and percentage differences are calculated as VMS - Tomtec. Indexing: TT LVEDV: BSA^1.05172. VMS LVEDV: BSA^1.1937558. TT LVESV: BSA^1.1630229, VMS LVESV: BSA^1.15831. ULOA Upper limit of agreement. LLOA Lower limit of agreement: Represents Average ± 1.96 x SD. VMS: Ventripoint software VMS 3.0, TT: TomTec Image Arena, LV: left ventricle, LA: left atrium, EDV: end diastolic volume, ESV: end systolic volume, EF: ejection fraction, BSA: body surface area. 95% CI Ninety-five percent confidence intervals (1.96 SD +/- mean), SD: standard deviation, SEM: standard error of the mean
