Figure 1: (a) Frontal projection of pulmonary artery angiogram showing suspicion for distal conduit stenosis (arrow). This area is seen as a radiolucent band at the bifurcation. (b) Frontal projection illustrating very low-pressure balloon sizing of the bifurcation stenosis. The angioplasty catheter is inflated at low pressure and shows an area of severe stenosis and tortuosity at the conduit insertion into the pulmonary artery bifurcation (arrow)
