Average trends in PV annular diameters in TGA fetuses (TGA‐PV): (A) versus trends in controls PV annular diameter (Control‐PV); (B) versus AoV annular diameter (Control‐AoV); (C) TGA with an IVS (TGA with IVS‐PV) and a VSD (TGA with VSD‐PV); and (D) with the TGA‐VSD fetuses further stratified on the basis of a TBA or non‐TBA anatomy (TGA with TBA‐PV). Average trend in AoV annular diameters in TGA fetuses (TGA‐AoV): (E) versus trends in controls of PV annular diameter (Control‐PV); and (F) AoV annular diameter (Control‐AoV). Trends in PV and AoV annular diameters in controls are shown (Control‐PV and Control‐AoV). Grey dots are individual measurements, and grey lines are individual trends. The 95% confidence intervals for both the fitted model and the control line as described by Vigneswaran et al21 are shown in blue (pulmonary valve) and red (aortic valve). Note that the 95% confidence intervals for the controls are smaller than the thickness of the line. AoV, aortic valve; IVS, intact inter‐ventricular septum; PV, pulmonary valve; TBA, Taussig‐Bing anomaly; TGA, transposition of the great arteries; VSD, ventricular septal defect [Colour figure can be viewed at http://wileyonlinelibrary.com]
