In this study we compared the efficiency of the right
and left ventricles to generate cardiac output in
subjects with repaired tetralogy of Fallot (rTOF) and
healthy volunteers. 4D Flow MRI was used to calculate
ventricular kinetic energy and great vessel flow.
Significant differences in ventricular efficiency were
observed between the two cohorts, with subjects with
rTOF much less efficient than healthy volunteers.
