Background: Advance 3D-visualization in congenital heart disease has gained importance in procedural planning, however it is still unclear which 3D-modelling technique represents the most informative tool in the surgical workup. We aim to assess which 3D modelling techniques should be preferred in the pre surgical evaluation of double outlet right ventricle (DORV).

Methods: Ten patients with DORV and complex ventricular septal defects were included in the present study. All the patients underwent biventricular repair. CT or cardiac MRI images were used to reconstruct patient-specific 3D anatomies. CT/cardiac MRI images and three different 3D models (computer based, physical 3D printed, and virtual reality model) were presented to two senior paediatric cardiac surgeons who reviewed each case blindly and were asked to decide on suitability of biventricular repair and possibility of performing arterial switch operation (ASO). The surgeons used the three different models to formulate a surgical plan and a comparison was made to actual operation performed.

Results: After reviewing traditional cross-sectional images (CT/CMR), the two surgeons correctly identified the surgical strategy (biventricular vs univentricular repair) in 75% of the cases; this improved to 85% after revision of the 3D printed models and to 95% after virtual reality visualisation. The use of the computer-based 3D model did not provide any additional benefit compared to traditional cross-sectional imaging techniques. When asked about suitability for ASO the answers were in agreement with actual surgery in 45% after reviewing of CT/CMR data; this increased to 55% and 60% after the inspection of the 3D printed and VR model, respectively.

Conclusion: 3D printed models and virtual reality models can support the evaluation of complex cases of DORV and the selection of cases of suitable for biventricular repair.
