Repaired tetralogy of Fallot (rTOF) caused diffuse fibrosis due to adverse ventricular reconstruction. T1 mapping was employed to observe the diffuse fibrosis. In patients, the native T1 and peak diastolic longitudinal velocity (Vz) were found to be different from the normal group. We aimed to investigate the relationship between left ventricular myocardial motion and myocardial fibrosis in patients with rTOF.
