With the increasing frequency of catheter-based interventions in congenital heart disease and structural heart disease, the use of fusion imaging has become a major enhancement for understanding complex anatomy and facilitating key steps in interventional procedures. Because transesophageal echocardiography and fluoroscopy are displayed in different visual perspectives, the interventional cardiologist must mentally reregister the images from the two modalities during the procedure. Echocardiography-fluoroscopy fusion (EFF) imaging displays the x-ray and ultrasound overlay images in the same visual perspective. This new technology allows for enhanced team communication, improved visual guidance, and more efficient navigation. The purpose of this review is to describe the EFF imaging technology, current uses of EFF imaging in congenital and structural heart disease, and future directions that will enhance this unique imaging technology to guide interventional procedures.

使用超声心动图-荧光检查融合成像进行先天性和结构性心脏病干预。

随着对先天性心脏病和结构性心脏病进行基于导管的干预的频率不断增加，融合成像的使用已成为理解复杂解剖结构和促进介入程序中关键步骤的主要手段。由于经食道超声心动图检查和透视检查显示的角度不同，因此介入心脏病专家必须在手术过程中从两种方式在精神上重新记录图像。超声心动图-荧光透视融合（EFF）成像以相同的视觉角度显示X射线和超声叠加图像。这项新技术可增强团队沟通，改善视觉指导并提高导航效率。这篇评论的目的是描述EFF成像技术，
