Three-dimensional rotational angiography (3D-RA) enables volumetric imaging through rotation of the C-arm of an angiographic system and real-time 3D reconstruction during cardiac catheterization procedures. In the field of congenital heart disease (CHD), 3D-RA has gained considerable traction, owing to its capability for enhanced visualization of spatial relationships in complex cardiac morphologies and real time image guidance in an intricate interventional environment. This review provides an overview of the current applications, strengths, and limitations of 3D-RA acquisition in the management of CHD and potential future directions. In addition, issues of dosimetry, radiation exposure, and optimization strategies will be reviewed. Further implementation of 3D-RA will be driven by patient benefits relative to existing 3D imaging capabilities and fusion techniques balanced against radiation exposure.
三维旋转血管造影（3D-RA）通过血管造影系统C型臂的旋转实现容积成像，并在心脏导管插入术过程中进行实时三维重建。在先天性心脏病（CHD）领域，3D-RA因其能够增强对复杂心脏形态中空间关系的可视化以及在复杂介入环境中进行实时图像引导而获得了广泛关注。本综述概述了3D-RA采集在CHD管理中的当前应用、优势和局限性以及潜在的未来发展方向。此外，还将综述剂量测定、辐射暴露和优化策略等问题。相对于现有的三维成像能力和融合技术，3D-RA的进一步应用将取决于患者受益情况，并与辐射暴露相平衡。
