Percutaneous catheter-based techniques for the treatment of structural heart disease are becoming more complex, and current imaging techniques have limitations: while fluoroscopy gives poor visualisation of cardiac anatomical structures, echocardiography is limited in its ability to detect the position of catheters and devices. The EchoNavigator® (Philips) live image guidance tool is a novel system that integrates real-time echocardiography with fluoroscopic X-ray imaging, optimising the guidance and positioning of devices. Use of the EchoNavigator system facilitates improved understanding of anatomical structures while showing enhanced visualisation of catheter and device movements. Early clinical experience suggests that the technology is feasible and safe, and provides enhanced understanding of the relationship between soft tissue anatomy and catheter devices in structural heart disease. The use of the EchoNavigator system can improve the confidence of interventional cardiologists in the targeting and positioning of devices in percutaneous interventions in structural heart disease, and has the potential to reduce procedural time, reduce the dosage of contrast and radiation and increase safety in the performance of procedural steps.
用于治疗结构性心脏病的经皮导管技术正变得越来越复杂，而当前的成像技术存在局限性：荧光透视对心脏解剖结构的可视化效果较差，超声心动图检测导管和器械位置的能力有限。EchoNavigator®（飞利浦）实时图像引导工具是一种将实时超声心动图与荧光X射线成像相结合的新型系统，可优化器械的引导和定位。使用EchoNavigator系统有助于更好地理解解剖结构，同时增强对导管和器械移动的可视化。早期临床经验表明，该技术可行且安全，能增强对结构性心脏病中软组织解剖结构与导管器械之间关系的理解。使用EchoNavigator系统可提高介入心脏病专家在结构性心脏病经皮介入中对器械靶向和定位的信心，并有潜力缩短手术时间、减少造影剂和辐射剂量以及提高手术步骤执行的安全性。
