Moving beyond size: vorticity and energy loss are correlated with right ventricular dysfunction and exercise intolerance in repaired Tetralogy of Fallot

Table 3 Subgroup correlation analysis of repaired tetralogy of Fallot (rTOF) patients who had infundibular or transannular patch repair (i.e. no conduit placement) and no pulmonary valve replacement (n = 36)
