Figure 4 Gadolinium-enhanced three-dimensional magnetic resonance angiography in a patient with a functional single ventricle, status post bidirectional Glenn shunt. (A) Subvolume maximal intensity project (MIP) image in an oblique coronal plane shows the left lower pulmonary vein (LLPV) with an adequate superior-inferior caliber. (B) Subvolume MIP image in the axial plane demonstrates that the LLPV is compressed between the descending aorta (AoD) and the left atrium (LA). RA = right atrium.
