Impact of 3D-printed models in meetings with parents of children undergoing interventional cardiac catheterisation

Abstract

BackgroundPaediatric interventional catheterisation has consistently improved in recent decades, with often highly successful outcomes. However, progress is still required in terms of the information delivered to parents and how parental anxiety is managed.AimTo investigate the impact of cardiac printed models on improving parental understanding and alleviating anxiety before interventional catheterisation.MethodsThe parents of children undergoing interventional cardiac catheterisation were prospectively enrolled in the study. A questionnaire highlighting knowledge and understanding of the condition and cardiac catheterisation per se was scored on a scale of 1–30. The State-Trait Anxiety Inventory (STAI), which generates current anxiety scores, was also used before and after the pre-catheterisation meeting. The “printing group” received an explanation of catheterisation using the device and a three-dimensional (3D) model, while the “control group” received an explanation using only the device and a manual drawing.ResultsIn total, 76 parents of 50 children were randomly assigned to a “control group” (n = 38) or “printing group” (n = 38). The groups were comparable at baseline. The level of understanding and knowledge improved after the “control group” and “printing group” meetings (+5.5±0.8 and +10.2±0.8; p < 0.0001 and p < 0.0001, respectively). A greater improvement was documented in the “printing group” compared to the “control group” (p < 0.0001). The STAI score also improved after the explanation was given to both groups (−1.8±0.6 and −5.6±1.0; p < 0.0001 and p < 0.0001). The greatest improvement was noted in the “printing group” (p = 0.0025). Most of the parents (35/38 from the “printing group”) found the models to be extremely useful.Conclusion3D-printed models improve parental knowledge and understanding of paediatric cardiac catheterisation, thereby reducing anxiety levels.

The effect of 3D modeling on family quality of life, surgical success, and patient outcomes in congenital heart diseases: objectives and design of a randomized controlled trial

“…The researchers enrolled 75 participants and found that using 3D-printed heart models was highly effective in helping families understand their child's disease. The study also assessed, similar to this plnned study, caregiver satisfaction and found a significant improvement after the educational intervention was provided Another RCT implemented by Karsenty et al 49 with 76 patients showed that 3D heart models improve parental knowledge and reduce their anxiety level.…”

Enhancing parental understanding of congenital heart disease through personalized prenatal counseling with 3D printed hearts

“…3D models have also been helpful in improving patients' and families' understanding of the underlying CHD anatomy and the need for a procedural intervention.

In our study, we investigated the impact of 3D-printed models on parental understanding of a specific CHD during pregnancy and after the prenatal diagnosis.…”

“…Furthermore, beyond enhancing precision and care through 3D TOE, the utilization of 3DE may improve education and communication among practitioners and with families, particularly when employing 3D printed models ( 15 , 16 ). Although CT images have been preferred to create 3D printed models because of their high spatial resolution, improvements in 3DE images resolution now also allow for detailed 3D printed models obtained from 3DE examinations ( 17 , 18 ).…”
