  1. EDV, end-diastolic volume; EF, ejection fraction; ESV, end-systolic volume, LV, left ventricular; RV, right ventricular; SV, stroke volume
  2. aDisplayed as mean ± standard deviation
  3. b Indicates significant differences with Standard BH technique (p < 0.05)
  4. Bias is the mean of the paired difference (Standard BH – Real-time) presented with standard deviation (SD) of the difference
  5. Limits of agreements are bias ± 1.96xSD
