CMR parameters and CMR-FT in repaired tetralogy of Fallot

Abstract Background Repaired tetralogy of Fallot patients develops postoperative complications that are in need for follow-up and re-intervention some circumstances. CMR myocardial feature tracking is a novel method allows quantification bi-atrial bi-ventricular mechanics deformation. So our aim to assess the added value cardiac magnetic resonance imaging its advanced analysis evaluation repaired patients. Results was done with post-processing 56 healthy volunteers . The commonest following order: pulmonary regurgitation subsequent right ventricular dilatation tricuspid followed by stenosis, dysfunction, outflow tract dilatation, left aortic mitral residual septal defect. All volumes were found be significantly increased compared those ( p < 0.001) also end-diastolic end-systolic indexed 0.001). Right function lower controls. Bi-ventricular CMR-FT indices atrial global longitudinal strain atrium correlated did not correlate ejection fraction volume indexed; 0.001, 0.109 0.565, respectively. circumferential obstruction without (− 16.26 ± 4.27% vs. − 12.2 3.78%, respectively). Pulmonary regurgitant related ventricle 0.027). Conclusion Biventricular volumetric measures controls; however, parameters both ventricles
