Fig. 1. Sinus venosus ASD with PAPVR Fig. 1. Sinus venosus ASD with PAPVR. (A) Axial cardiac computed tomography image in a 53-year-old-male demonstrates a septal defect (*) between the left atrium and the superior vena cava-right atrial junction, consistent with sinus venosus ASD. (B) Axial image demonstrates a right superior pulmonary vein (arrow) draining into the superior vena cava, suggestive of PAPVR. ASD: atrial septal defect, PAPVR: partial anomalous pulmonary venous return. Fig. 1. Sinus venosus ASD with PAPVR.
