In addition to a correct prenatal diagnosis of congenital heart disease (CHD), comprehensive parental counseling is crucial to ensure that parents are well-informed about the condition of the fetus. This study aims to investigate whether there is a significant difference in the information acquired by parents through traditional counseling, utilizing 2-dimensional (2D) illustrations and images, compared to an advanced approach utilizing personalized three-dimensional (3D) printed models of the fetal heart developed from 3D ultrasound imaging.
This study, designed as a pilot randomized control trial, enrolled pregnant women with gestational ages greater than 18 weeks, whose fetuses were diagnosed with CHD and referred to our center between November, 2020 and June, 2021. Two groups of patients were included in the study. The first group received standard medical counseling with 2D images and illustrations, while the second group underwent advanced counseling with 3D-printed patient-specific heart models. Both groups were then required to complete the same survey in which the knowledge of the CHD was investigated. The 3D models were created from 3D ultrasound imaging and printed using resin materials in both 1:1 and 5:1 scale.
A comparison of the scores obtained from the two groups revealed that 3D visualization of the fetus's heart has the potential to increase parental knowledge about CHD and the required surgical procedures. Furthermore, all couples expressed interest in receiving a 1:1 scale model of their baby's heart.
Personalized prenatal counseling with 3D-ultrasound-based heart models positively impacts parents' understanding of CHD. The use of 3D models provides a more comprehensive and accessible representation of the condition, contributing to an increased knowledge gain, and potentially helping to support informed decisions regarding their child's care.
除了正确诊断先天性心脏病（CHD）外，全面的父母咨询对于确保父母充分了解胎儿的情况至关重要。本研究旨在调查通过传统咨询（利用二维[2D]插图和图像）与利用从 3D 超声成像开发的胎儿心脏个性化三维[3D]打印模型的先进方法相比，父母获取的信息是否存在显著差异。
本研究设计为一项前瞻性随机对照试验，纳入了 2020 年 11 月至 2021 年 6 月期间因胎儿 CHD 就诊于本中心且孕周大于 18 周的孕妇。研究纳入两组患者。第一组接受标准的 2D 图像和插图医学咨询，第二组接受 3D 打印患者特异性心脏模型的高级咨询。然后，两组均需完成相同的调查，以评估 CHD 知识。3D 模型是根据 3D 超声成像创建的，并使用树脂材料以 1:1 和 5:1 的比例打印。
两组的评分比较表明，胎儿心脏的 3D 可视化有潜力增加父母对 CHD 和所需手术的了解。此外，所有夫妇都表示有兴趣获得其婴儿心脏 1:1 比例模型。
基于 3D 超声的个性化产前咨询通过心脏模型可积极影响父母对 CHD 的理解。3D 模型的使用提供了更全面、更易于理解的疾病表现形式，有助于增加知识获取，并可能有助于支持其对子女护理的知情决策。
