Figure 1

(A) The series of experimental virtual EC Fontan connection options ranging from options with the EC conduit offset toward the LPA (in Option #1) to toward the RPA (in Option N). (B) The patient-specific 3D LT Fontan reconstruction depicted along with a positioned and scaled EC Fontan template matching the hydraulic diameter of the patient-specific IVC. C) The ideal EC Fontan configuration which resulted in 38% reduction in mean pressure gradient from the IVC to PAs, superimposed with a colored model of the virtual pre-Fontan Glenn anastomsis depicting a likelihood (min: 0 to max:1) estimated by a regional distance mapping function to an guide optimal incision which will result in this ideal EC Fontan configuration. (D) illustrates flow velocity vs. time plots generated from CFD in the patient-specific LT case, the virtual pre-operative Glenn configuration the ideal EC Fontan construction, and (E) shows the corresponding time-varying LPA outflow splits over time for each case.
