A–O CMR revealed: Dilated non-hypertrophied RV, moderate PR, RF = 45%, no PS, moderate TR, RF = 32%, mild AR, RF = 17%, enhancement related to TAP and VSD patch. A 23-year-old female patient, diagnosed as tetralogy of Fallot, underwent trans-annular patch repair at age of 1 year. The patient was referred for baseline CMR study for 1st follow-up. A 4-chamber cine images at diastole, B at systole and C right 2-chamber cine image at systole showing dilated, non-hypertrophied right ventricle at end-diastolic phase and dephasing jet of tricuspid regurgitation during ventricular systole as well. D, E, F Coronal pulmonary phase-contrast velocity encoding sequence (in-plane, Venc 1.5 m/s); anatomy, magnitude and phase images showing no aliasing across denoting no residual stenosis. G Coronal pulmonary phase-contrast velocity encoding sequence (in-plane pulmonary with Venc 1.5 m/s); phase image showing dephasing regurgitant pulmonary jet. H Phase-contrast velocity encoding sequence at sub-pulmonic level (through-plane, Venc 1.5 m/s); phase image for better assessment of the backward blood volume and consequently better assessment of the regurgitant fraction as well. I, J 3-chamber left cine image at diastole and LVOT cine image at diastole showing dephasing jet of aortic regurgitation, regurgitant fraction calculated from the phase-contrast velocity encoding sequence (through-plane at aortic valve), RF = 17%. K, L, M Phase-contrast velocity encoding sequence at sub-aortic level (through-plane, Venc 1.5 m/s); anatomy, magnitude and phase images for better assessment of the backward blood volume and consequently better assessment of the regurgitant fraction as well. N, O Short axis and 3-chamber late gadolinium enhancement sequences (LGE) showing enhancement at the site of TAP and VSD patch
