Limited experience with 3D print technology has been reported for surgical planning in infants with congenital heart disease. We present 5 infants with complex intracardiac anatomy for whom 3D cardiac models from gated cardiac CT angiograms facilitated surgical planning.

Case 1: Term 2-day-old infant with d-transposition of the great arteries (TGA), large anterior malalignment ventricular septal defect (VSD), and severe aortic arch hypoplasia. The 3D cardiac model confirmed feasibility of biventricular repair using a Yasui-type operation, with Norwood arch reconstruction, Rastelli VSD closure, and right ventricle to pulmonary artery (RV-PA) conduit placement.

Case 2: 2-month old, ex-34-week premature infant with double-outlet right ventricle (DORV), side-by-side great arteries, large remote predominantly-subaortic VSD, and pulmonary stenosis (PS). The 3D cardiac model highlighted the remoteness of the VSD from the outflow tracts, prompting right ventricular outflow tract patch augmentation without VSD closure when the patient developed hypercyanotic spells.

Case 3: Term 7-day-old infant with Goldenhar syndrome, D-TGA, large posterior malalignment VSD with inlet extension, and PS. The first 3D cardiac model raised concern that VSD closure would be difficult as a newborn due to VSD size, prompting placement of a BT shunt and pulmonary artery band. The second 3D model at 11 months of age demonstrated feasibility of biventricular repair with Rastelli VSD closure and RV-PA conduit placement.

Case 4: Term 2-day-old infant with 22q11.2 deletion syndrome, type B interruption of a right aortic arch, aberrant left subclavian artery, posterior malalignment VSD, small bicuspid aortic valve, and superior-inferior branch pulmonary artery relationships. The 3D cardiac model demonstrated need for VSD enlargement to enable complete repair with Yasui operation with LeCompte maneuver.

Case 5: Term 3-week-old infant with mesocardia, ventricular inversion, DORV, L-malposed great arteries, subpulmonic VSD, multilevel PS, and mitral chordal attachments to the crest of the ventricular septum. The 3D cardiac model suggested that VSD enlargement might enable a double switch operation with Rastelli VSD baffle. However, during the operation at 20 months old, mitral chordal apparatus prevented VSD enlargement, necessitating bidirectional Glenn instead. Read More

3D printed models from MRI scans can effectively demonstrate the surface structure of the brain. Previous workflows focus on adult brains as a basis for prints. Our database of pediatric MRI brains who had perinatal hypoxic ischemic injury and presented late for imaging, with pathology causing cortical surface irregularities and parenchymal cysts. Difficulties arise in accurate depiction of the cortex on 3D print models in these pathologic brains. We aim to demonstrate effective workflows to accurately and efficiently print 3D models of especially pathologic pediatric MRI brains. Also, to critically and empirically test and refine the various steps involved in producing 3D print models which include segmentation of the MRI volume into tissue classes, generation of a surface model from this volume, preparation and final print of a 3D model.

Pediatric kidney abnormalities, such as urinary tract dilation (UTD), are common, and current reporting methods vary significantly. There's a need for more precise evaluation methods. Using automated 3D kidney volume measurements from ultrasound (US) offers an alterantive objective approach. Our aim is to evaluate the diagnostic potential of automated 3D kidney volume measurements for detecting and categorizing UTD, comparing their accuracy with clinical assessment. Read More

Three-dimensional (3D) printed models of patient anatomy are increasingly becoming a component of the healthcare practice of many physicians. Here, we investigate physician perceptions of an in-house high-fidelity medical 3D-printing service in a large pediatric health system. We aim to elucidate how physicians perceive 3D-printed models assist in their roles as healthcare providers and to illustrate how a 3D-printing service may add value to a healthcare system.

Arthrogryposis multiplex congenita is a clinical finding that includes congenital contractures affecting 2 or more areas of the body and is a component of over 300 disorders. Treatments goals are joint mobilization, splinting for improved function and position, and therapy for improved strength. Limb deformities that restrict motion may be treated surgically with understanding of unique patient joint alignment, bone morphology, and muscle and ligament integrity required for adequate surgical planning. We discuss 3 cases in which advanced imaging techniques including CT, MRI and 3D model printing were used for improved understanding of complex patient anatomy and dysmorphology. Read More
