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

Three-dimensional (3D) imaging has emerged as a valuable tool in diagnosing pediatric Müllerian duct anomalies (MDAs), offering superior anatomical visualization and assessment compared to traditional imaging techniques with two-dimensional ultrasound. MDAs are frequently associated with other congenital anomalies of the cervix, vagina, or urinary tract, and are a common cause of infertility and pregnancy loss after adolescence.

In pediatric patients, MDAs are often discovered incidentally during imaging for other conditions. Magnetic resonance imaging (MRI) is the preferred modality for evaluating MDAs in children, providing multiplanar capabilities and detailed soft tissue characterization while avoiding ionizing radiation. MRI protocols for MDAs typically include T2-weighted sequences for visualizing uterine morphology and T1-weighted sequences to detect blood products in cases of associated endometriosis or hematometra .

The use of 3D MRI techniques allows for enhanced depiction of uterine and vaginal anatomy, and is particularly advantageous in differentiating complex anomalies such as septate and bicornuate uteri. Additionally, 3D reconstructions can provide a virtual hysterosalpingogram (MR-HSG), offering a comprehensive assessment of the reproductive tract without the need for invasive procedures. 3D imaging's accuracy extends to the detection of associated renal anomalies, given the concurrent development of the urinary and reproductive systems. Identifying these anomalies early is crucial for planning surgical interventions that may involve both gynecologic and urologic components .

Overall, 3D imaging significantly enhances the diagnostic accuracy and management of pediatric Müllerian duct anomalies. By providing detailed anatomical insights and allowing for non-invasive classification, it plays a critical role in guiding treatment strategies, reducing the need for repeat surgeries, and improving long-term reproductive outcomes for affected patients.

The purpose of this educational exhibit is to:
1. Review the embryology, classification, and imaging features of Müllerian duct anomalies using 3-dimensional imaging
2. Review the indications and techniques for surgical management of Müllerian duct anomalies in pediatric patients
3. Provide sample cases and clinical courses of patients with specific Müllerian duct anomalies with tips for implementation of 3-D imaging
4. Allow learners to test their knowledge with a quiz. Read More

Knee deformity is the most common and complex lower extremity abnormality associated with Thrombocytopenia Absent Radius (TAR) syndrome. Conventional pre-operative imaging includes radiographs and computed tomography (CT) for assessment of joint alignment. We report utilizing 3-D MRI series and manual segmentation on commeicially available software to create 3-D printed models for pre-operative planning in a TAR syndrome patient with largely unossified epiphyses who had unusually severe femoral anteversion and genu varum. We discuss the methods used for imaging and segmentation as well as the value and limitations of the 3D print in pre-operative planning for this case. Even with the limitations we encountered, better understanding of the spatial relationships and joint alignment was achieved with 3-D model generation and aided in planning for correction of the knee varus deformity and femoral torsion. In addition, the diagnostic MRI information provided the basis to forgo construction of cruciate ligaments at this stage due to an increased risk of failure related to severe joint deformity. Because the prognosis for TAR syndrome is good if the child survives the first 2 years, it is important that orthopedic interventions are well planned to give a good outcome. Utilization of advanced imaging tools such as 3D imaging and printing may aid in definitive surgical planning in complex cases such as this one, and MRI can be used to generate usable anatomical models for pre-operative planning in children with incompletely ossified epiphyses.

Retinoblastoma is an aggressive malignant tumor and the most common malignant intraocular tumor in children. The key to better treatment is early detection, before it metastasizes. We aim to provide better quantifiable measurements to assist the clinician in the evaluation of tumor response.
Currently, 2D sonography is performed to confirm the diagnosis, and after each sequential treatment. Thus, a change in tumor size during treatment is made by 2D evaluation only. Three-dimensional (3D) ultrasonography is an enhancement of the ultrasonographic technique that allows an examiner to obtain, non-invasively, 3D volumetric images. 3D ultrasound imaging is primarily performed in the Ob/Gyn setting. However, more and more it is being used for other areas of the body. We think that 3D technology may be particularly useful since retinoblastomas can have very irregular shapes and, therefore, simpler techniques to estimate volumes such as the performance of three orthogonal two-dimensional measurements multiplied by 0.523 to estimate the volume of an oval structure using the ellipsoid formula may be unreliable. We present several case studies performed at our institution with a developed protocol for such imaging along with the results of the study. Read More

Fluoroscopy of the upper GI tract (UGI) can be difficult to master given the time-sensitive nature of the examination, the necessary hand-eye coordination, the complex button layout and broad featureset of the fluoroscopic equipment, the desire for minimizing radiation dose, and the required understanding of normal anatomy. Additionally, encountering abnormal findings for the first time, particularly before one is familiar with normal findings, can lead to confusion and increased difficulty in performing the examination. The use of 3D printed models of normal anatomy in pediatric fluoroscopic UGI training simulation has previously been demonstrated as a viable alternative to learning on live patients; however, such a technique has not previously been used with known pathological anatomic configurations.

Learning the skills used to master pediatric fluoroscopic exams can be challenging. Hand-eye coordination and specific timing is required while at the same time being mindful of radiation dose and interpreting the images generated in real time. Training on live neonates will often mean less diagnostic exams and increased radiation dose for those exams.

An inexpensive reusable simulator model was devised to allow residents practice of upper GI fluoroscopic exams to increase efficiency using ALARA principles and utilizing 3D printing technology off-the-shelf dolls. Generic gastrografin provided a cost effective contrast medium as its concerns in real UGI studies are of no issue on the training models. A 30ml bottle of generic gastrografin can be purchased for less than $20, which would last for several simulated exams.

The 3D model was based on a computer generated imagery (CGI) mesh of a stomach which was modified in Blender™ to try to best replicate the full duodenum and effect of the ligament of Treitz. The final iteration of the model was printed in polylactic acid polymer (PLA) in a size that would fit inside the plastic doll, which already contained portions of the necessary tubing. The model was sealed to be watertight.

Testing under fluoroscopy showed that the model behaved similar enough to an infant when placed in various positions then filled with an appropriate volume contrast.

There are several limitations of this model including the lack of the distractions of a real pediatric patient. Also, the flow of contrast is purely gravity dependent without the effects of sphincters and peristalsis. Overlying skeletal structures and bowel gas are not represented, however these could also be simulated in various ways.

Future work on this and similar projects could include expansion into other organ systems such as the colon. 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.

Ectopia cordis is a rare congenital condition where the heart is located outside the chest cavity, often associated with midline defects like omphalocele and Pentalogy of Cantrell. This condition presents significant challenges in surgical management and has a high mortality rate due to complications related to cardiac and associated anomalies.

A newborn delivered at 37 weeks gestation was admitted for surgical management of ectopia cordis and omphalocele. Prenatal imaging suggested Pentalogy of Cantrell. An echocardiogram was performed, but visualization was limited due to the heart’s external position, hindering comprehensive assessment. A follow-up CT angiogram confirmed ectopia cordis with complex cardiac and vascular findings. The left-sided superior vena cava drained into the coronary sinus, and the inferior vena cava was dilated, draining into the right atrium. The right atrium was dilated, while the left atrium was elongated with normal pulmonary venous drainage. A 4 mm atrial septal defect and a possible 2 mm perimembranous ventricular septal defect were noted. The right ventricle appeared normal, but the left ventricle was hypoplastic. The aortic root and ascending aorta were hypoplastic, with Z-scores ranging from -3.20 to -4.90, while the aortic isthmus and descending aorta were within normal limits. The pulmonary arteries were normal in size, and a large PDA was observed.
3D modeling was used to assess the feasibility of surgical repair and chest closure. The heart outside the chest measured 30.65 ml, and the total intrathoracic volume was 107.31 ml. The combined volume of the lungs and pleural effusions totaled 77.69 ml, leaving limited space for the heart within the thoracic cavity. This made the prospect of repositioning the heart into the chest highly challenging, with significant risk of compressing the lungs or other critical structures. The baby passed away during the hospital stay.
This case highlights the role of CTA and 3D modeling in congenital heart disease, illustrating how these tools can assist in evaluating spatial constraints and informing surgical decisions in complex conditions like ectopia cordis. Read More

Developmental dysplasia of the hip (DDH) is a common congenital problem affecting up to 3% of the the population. If untreated, DDH may lead to hip dislocation and premature osteoarthritis. Current DDH diagnosis is highly operator-dependent as it relies on 2D ultrasound. 3D ultrasound offers more complete, and potentially more reliable, imaging of infant hip geometry. However, it is unclear whether 3D ultrasound images, noisy with artifacts and reconstructed by proprietary algorithms from non-parallel beams, give accurate 3D shape information. We sought to validate the fidelity of acetabular surface models obtained by 3D ultrasound by comparison with those obtained concurrently from MRI. Read More

Prenatal diagnosis of esophageal atresia (EA) remains challenging, with indirect signs such as polyhydramnios, a small or absent stomach bubble, and a dilated upper esophageal pouch often being nonspecific. Only 10-40% of EA cases are diagnosed prenatally. Fetal MRI can overcome ultrasound limitations; however, constraints like motion can hinder evaluation of the esophagus. One approach to improve image quality is super-resolution imaging with slice-to-volume reconstruction (SVR). This technique enhances diagnostic accuracy by generating high-resolution 3D images from standard fetal MRI slices. We present two instances where super-resolution imaging with SVR was employed to accurately diagnose EA and assess the presence or absence tracheoesophageal fistulas (TEF).

Case 1: A 30 3/7-week gestation male fetus was referred for fetal MRI following ultrasonographic findings of a dilated right atrium, a single umbilical artery, a small fetal stomach, and a urinary tract dilation observed at 27 2/7 weeks. Fetal MRI revealed a dilated upper esophageal pouch with a small amount of fluid in the distal esophagus, and a diminutive stomach. 3D-rendered super-resolution images demonstrated a dilated atretic upper esophageal pouch and a TEF originating from the left mainstem bronchus. The application of super-resolution imaging with SVR was crucial to determine the precise origin of the TEF from the left mainstem bronchus, findings that were later confirmed by bronchoscopy and surgery.

Case 2: A 33 2/7-week gestation male fetus was referred for fetal MRI due to polyhydramnios and inability to visualize the stomach on an ultrasound performed at 31 weeks. Fetal MRI confirmed polyhydramnios with a distended, fluid-filled proximal esophagus, consistent with EA. The stomach was decompressed, and the distal esophagus was not visualized. 3D-rendered super-resolution imaging with SVR confirmed the dilated upper esophagus and revealed that it ended 0.5 cm below the level of the carina. The imaging also demonstrated a gap between the distal end of the esophageal pouch and the gastroesophageal junction at the level of the diaphragm, supporting the absence of the distal esophagus.

The use of super-resolution imaging with SVR provided detailed, pre-surgical 3D anatomical depictions in both cases of EA, with and without TEF. This technique demonstrates significant potential for accurately delineating the relevant surgical anatomy, which can improve surgical planning and outcomes. Read More
