EVALUATION OF RIGHT VENTRICULAR MYOCARDIAL DEFORMATION AND TRICUSPID VALVE DISPLACEMENT IN REPAIRED TETRALOGY OF FALLOT USING FEATURE TRACKING MAGNETIC RESONANCE STRAIN

Background The objective of this study was to investigate into correlation between right ventricular (RV) myocardial deformation and tricuspid valve (TV) displacement, and functional parameters in repaired tetralogy of Fallot (TOF) compared to normal subjects using new magnetic resonance tracking pr...

Zusammenfassung:Background The objective of this study was to investigate into correlation between right ventricular (RV) myocardial deformation and tricuspid valve (TV) displacement, and functional parameters in repaired tetralogy of Fallot (TOF) compared to normal subjects using new magnetic resonance tracking program. Developing CMR software applying a semi-automatic segmentation program of the endocardium and epicardium was used to perform global longitudinal and circumferential strain, strain rate (GLS/GLSR and GCS/GCSR) in mid-systole (MS) and end-diastole (ED).
