Key result
Adults with repaired Tetralogy of Fallot had reduced multi-wall averaged right ventricular longitudinal strain compared to healthy controls.
Why the study?
In patients with repaired Tetralogy of Fallot, detailed assessment of right ventricular function is important for management and timing of pulmonary valve re-intervention, prompting evaluation of two-dimensional multi-plane echocardiography.
Does two-dimensional multi-plane echocardiography provide feasible and reliable assessment of right ventricular function in adults with repaired Tetralogy of Fallot compared to 3D echocardiography and healthy controls?

Does two-dimensional multi-plane echocardiography provide feasible and reliable assessment of right ventricular function in adults with repaired Tetralogy of Fallot compared to 3D echocardiography and healthy controls?
2D multi-plane echocardiography is a highly feasible method for detailed regional and global right ventricular functional assessment in adults with repaired Tetralogy of Fallot, correlating well with 3D RV ejection fraction.

2D MPE supports feasible RV assessment in repaired ToF; leaves open prospective validation against outcomes before wider adoption.
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.

Bowen et al. (2021) conducted an observational in Repaired Tetralogy of Fallot (n=124). Repaired Tetralogy of Fallot vs. Healthy age and gender matched controls was evaluated on Multi-wall averaged right ventricular wall longitudinal strain (RV-LS) (p=<0.001). Adults with repaired Tetralogy of Fallot had reduced multi-wall averaged right ventricular longitudinal strain compared to healthy controls.
