| In patients with repaired Tetralogy of Fallot (ToF), detailed assessment of right ventricular (RV) function is important for management and timing of possible pulmonary valve re-intervention. The aim of this study was to evaluate RV function using two-dimensional multi-plane echocardiography (2D MPE), a novel four-wall imaging method obtained from one apical acoustic window utilising electronic plane rotation. In sixty-two ToF patients (aged - 28 [22, 39] years, 65% male), systolic function of four different RV walls (lateral, anterior, inferior and inferior coronal) were evaluated using MPE. Tricuspid annular plane systolic excursion (TAPSE), tricuspid annular peak systolic velocity (RV-S ') and RV wall longitudinal strain (RV-LS) measurements were compared with those of matched healthy individuals. 2D MPE measurements were highly feasible across the four RV walls (93.5-100% for TAPSE/S '; 66.1-95.1% for RVLS) and could be performed more reliably than 3D RV ejection fraction (RVEF - 56.5%). All functional values were significantly reduced when compared to the control group (p < 0.001). Higher RV-LS values were seen in the lateral (- 17.8 +/- 4.5%) and inferior (- 17.8 +/- 4.2%) walls compared to the anterior (- 15.9 +/- 3.8%) and inferior coronal (- 15.1 +/- 3.9%) walls. 3D RVEF correlated strongest with RV-LS values from the lateral (r - 0.50; p = 0.002) and anterior walls (r - 0.74; p < 0.001) and furthermore the four-wall average (r - 0.57; p = 0.001). 2D MPE evaluation of the RV is highly feasible in ToF patients. This novel method provides new insights into regional RV wall function, enabling a more comprehensive and quantitative approach to RV assessment in daily clinical practice. |
