This study aims to evaluate biventricular myocardial circumferential kinetic energy (KE_Ø) for assessment of regional myocardial function in repaired tetralogy of Fallot (rTOF) patients with preserved global cardiac function. The tissue phase mapping (TPM) was acquired in the basal, mid, and apical slices in the left and right ventricles. We found the altered KE values and abnormal distribution of three-directional %KE in rTOF patients. In conclusion, the altered myocardial KE_Ø may provide useful information for assessment of regional myocardial function in rTOF patients with preserved global cardiac function.
