The role of echocardiography in the assessment of right ventricular systolic function in patients with transposition of the great arteries and atrial redirection
Place de l’échocardiographie transthoracique dans l’évaluation du ventricule droit systémique chez les patients porteurs d’une transposition des gros vaisseaux opérés par switch atrial

Figure 1 : 

Common parameters of right ventricular systolic function. Parameters commonly used for assessment of right ventricular systolic function are displayed in the panels A–E. A. Right ventricular ejection fraction (RVEF) using monoplane Simpson’s method as calculated by dividing the difference between the RV end-diastolic volume and the RV end-systolic volume by the RV end-diastolic volume in two-dimensional and apical four-chamber (A4C) view. B. S’ Tissue Doppler Imaging (TDI) to the tricuspid ring in lateral A4C window. C. Tricuspid annular plane systolic excursion (TAPSE) in lateral A4C view and M-mode. D. dP/dT in continuous Doppler in A4C at the level of Tricuspid Regurgitation (TR). E. Tei index (a–b)/a, in which a=(isovolumic contraction time+isovolumic relaxation time+ejection time) and b=ejection time.

Correlations between the various echocardiographic parameters of right ventricular systolic function and estimation of right ventricular ejection fraction by MRI (r =correlation coefficient and P =probability). 2D: two-dimensional; MRI: magnetic resonance imaging; RVEF: right ventricular ejection fraction; RVSF, right ventricular systolic function; S’ TDI: peak systolic velocity at the junction of the RV free wall and the tricuspid annulus, assessed with pulsed tissue Doppler imaging; TAPSE: tricuspid annular plane systolic excursion.
