A technological platform (MediGuide) has been recently introduced for non-fluoroscopic catheter tracking. In several studies, we have demonstrated that the application of this non-fluoroscopic catheter visualization system (NFCV) reduces fluoroscopy time and dose by 90-95% in a variety of electrophysiology (EP) procedures. This can be of relevance not only to the patients, but also to the nurses and physicians working in the EP lab. Furthermore, in a subset of indications such as supraventricular tachycardias, NFCV enables a fully non-fluoroscopic procedure and allows the lab staff to work without wearing lead aprons. With this protocol, we demonstrate that even complex procedures such as ablations of atrial fibrillation, that are typically associated with fluoroscopy times of >30 min in conventional settings, can safely be performed with a reduction of >90% in fluoroscopy exposure by the additional use of NFCV.
最近推出了一种用于非荧光透视导管追踪的技术平台（MediGuide）。在多项研究中，我们已经证明，这种非荧光透视导管可视化系统（NFCV）在各种电生理（EP）手术中可将荧光透视时间和剂量减少90%-95%。这不仅对患者有意义，对在EP实验室工作的护士和医生也有意义。此外，在某些适应症（如室上性心动过速）中，NFCV可实现完全非荧光透视手术，并允许实验室工作人员不穿铅围裙进行操作。通过本方案，我们证明，即使是像房颤消融这样的复杂手术，在传统情况下通常与超过30分钟的荧光透视时间相关联，通过额外使用NFCV，也可以在将荧光透视暴露减少90%以上的情况下安全进行。
