Fig 3 Postnatal changes of the Z-score of the pulmonary valve annulus diameter (PVA [Z]) according to the types of right ventricular outflow tract reconstruction on repair in the systemic-pulmonary shunt group. PVA preservation was eventually achieved in 16 of 19 patients (84%) with a PVA (Z) equal to or greater than −4.0 on initial preshunt echocardiography, whereas all patients with PVA (Z) less than −4.0 received transannular patching.

Fig 4 Receiver operating characteristics curve analysis to determine the value of the initial Z-score of the pulmonary valve annulus diameter (PVA [Z]) above which PVA preservation is predicted on repair after a systemic-pulmonary shunt. (AUC = area under the curve; CI = confidence interval; Sens = sensitivity; Spec = specificity.)
