Figure 2

3D-printed hollow model of right atrial isomerism, visceral heterotaxy, dextrocardia, common atrium, and hemiazygos continuity to left superior vena cava (Case 11). (A) Right anterior oblique view with the ventricular apex removed. Innominate vein and the interrupted inferior vena cava connected by the hemiayzgos vein drain into left-sided atrium via left superior vena cava. The hepatic veins also drain to the left-sided atrium. (B) Posterior view. Abbreviations: AAo: ascending aorta, DAo: descending aorta, Haz: hemiazygos vein, HV: hepatic vein, innom art/vein: innominate artery and vein, IVS: interventricular septum, L-AA: left-sided morphologically right atrial appendage, LCCA: left common carotid artery, LPA: left pulmonary artery, LPV: left pulmonary vein, LSCA: left subclavian artery, L-SVC: left superior vena cava, LV: left ventricle, PT: pulmonary trunk, R-AA: right-sided morphologically right atrial appendage, RPA: right pulmonary artery, RPV: right pulmonary vein, RV: right ventricle.
