2. Fig 1
Mean change in right ventricular fractional area change (RV-FAC) for patients with recurrent coarctation was calculated using a coarctation index (CI) of 0.75 or higher as a cutoff value. Patients with a CI of less than 0.75 had a significantly lower RV-FAC at the pre-cavopulmonary shunt (CPS) evaluation than patients with a CI of 0.75 or higher. (Stage I = Norwood palliation.)

3. Fig 2
The correlation is shown between coarctation index (CI) values and the difference in right ventricular function fractional area change (RV-FAC) between the post-stage I evaluation and the pre-cavopulmonary shunt (CPS) evaluation (ΔS1-S2 RV-FAC). A lower CI is associated with a greater decrease in RV function between stage I discharge and pre-CPS evaluation.

4. Fig 3
For patients who underwent balloon dilation for recurrent coarctation, mean right ventricular-fractional area change recovers to a level at the pre-Fontan assessment that is not significantly different from that of patients who did not need balloon dilation for recurrent coarctation. (CPS = cavopulmonary shunt.)
