Figure Legends:
Figure 1: Digital Illustration of operative correction
Fig1A: Illustrating pre-operative MPA-LPA non-confluence with 10mm gap. Note the atretic pulmonary valve with no flow from RV to MPA.
Fig1B: Illustrating incisions made and transection of PDA. Arrow lines illustrate the translocation of MPA from A to A1 and B to B1.
Fig1C: Illustrating rotational and translational alignment of transected MPA with LPA.
Fig1D: Illustrating corrected flow and MPA-LPA anastomosis.
Figure 2: Pre-operative Computer Tomography (CT) imaging
Fig 2A: Axial CT image showing severe stenosis (arrow) of LPA (L) with MPA continuing as RPA (R)
Fig 2B: 3D reconstructed CT image demonstrating continuation of MPA (M) as RPA (R) noting severe LPA (L) stenosis (arrow)
Fig 2C: 3D reconstructed CT image showing bifid PDA supplying LPA (L) and RPA (R).

Figure 4: Post-operative Computer Tomography (CT) Imaging
Fig 4A: Axial CT image showing good patency of MPA-LPA anastomosis and flow 6 months later.
