Model of a two year old subject. Generated using MR Cine, MR Angiography, and echocardiography. The subject has a large right-sided ventricle that conducts blood to an anteriorly positioned aorta, a ventricular septal defect, a small left-sided ventricle that communicates with a stenotic pulmonary valve, and anomalous pulmonary veins that connect to the right side of a common atrium. Panel A shows a graphical rendering of the finished model with a cut to demonstrate intra-cardiac anatomy. Panel B shows a photograph of the model fabricated with a MakerBot Replicator 2X.
