Figure Legends:
Figure 1: Digital Illustration of pathology and operative correction
Fig1A: Illustration of pre-operative MPA-LPA non-confluence with 10mm gap. Note the atretic pulmonary valve with no flow from RV to MPA.
Fig1B: Illustration of incision sites as well as ligation and transection of patent ductus arteriosus. Lines illustrate the translocation of MPA from points A to A1 and B to B1.
Fig1C: Illustration of rotational and translational alignment of transected MPA with LPA.
Fig1D: Illustration of corrected flow and MPA-LPA anastomosis.
Figure 2: Computer Tomography (CT) imaging
Fig 2A: Pre-operative CT image showing non-confluence of LPA with MPA-RPA.
Fig 2B: Post-operative CT image showing good patency of MPA-LPA anastomosis 4 months later.
Figure 3: Annotated, intraoperative photograph of MPA-LPA anastomosis noting tension free anastomosis. RV and atretic pulmonary valve can be seen along with sutured cardiac end of MPA.
