#TTE VTI was hemodynamic parameter measured by TTE. *Mean = (TEBT + TTE)/2. **Bias = TEBT – TTE. Bold data indicates calculated data or data estimated from provided graphs. LOA, limits of agreement; NS, not specified; PDA, patent ductus arteriosus; PE, percentage error; PFO, patent foramen ovale; SD, standard deviation; TGA, transposition of great arteries.
