Figure 1: Schematic operative steps. (A) Dashed line indicates extent of incision, (B) star mark (∗) demarcates distal point on middle of posterior wall of main pulmonary artery 5 mm proximal to right pulmonary artery origin, (C) square-shaped polytetrafluoroethylene patch with side measuring “L” is fashioned, (D) Corner “a” of patch sewn to distal point, (E) corner “c” of patch sutured to endocardium of right ventricular outflow tract and continued in both directions to stitch point “b” and “d,” (F) TAP overlaid including myocardial aspect of right ventricular outflow tract, (G) completed view, (H) cross-sectional view; I: Closed position, II: Open position. TAP: Transannular patch
