CMR 4D flow with right ventricle (RV) kinetic energy
(KE) and flow component analyses showed reduced RV direct flow and efficiency
index, increased RV residual volume, RV peak systolic, systolic and peak E-wave
KE normalized to RV end-diastolic volume in rTOF compared with normal controls
Detection of rTOF with preserved EF: ROC curves
comparing the diagnostic performance of RV direct flow, efficient index and RV
EF with respective AUC values. rTOF: repaired tetralogy of Fallot; EF: ejection
fraction; RV: right ventricle; efficiency index: effective cardiac index/RV
systolic KEiEDV; KEiEDV: kinetic energy normalized to
end-diastolic volume.
Demographics, left ventricular (LV) and right ventricular (RV)
flow analysis parameters in controls and repaired tetralogy of Fallot (rTOF)
