A Rare Case of Concordant Atrioventricular Connection to L-Looped Ventricles in Situs Solitus: 4-Dimensional Magnetic Resonance Imaging and 3D Printing

An infant male presented with the rare anatomy consisting of situs solitus, concordant atrioventricular connections to L-looped ventricles, double outlet right ventricle (DORV), and hypoplastic aortic arch. 6 months after neonatal arch repair, morphologic function deteriorated, surgical evaluation was undertaken determine if either biventricular repair a systemic left or ventricular exclusion possible. After initial echocardiography, magnetic resonance imaging (MRI) used create detailed axial 4-dimensional (4D) images 3-dimensional (3D) printed models. The this rare, complex case its use in pre-surgical planning is presented.
