Abstract：
UNASSIGNED: Fluoroscopy-guided catheter ablation has become the gold standard for treatment of cardiac arrhythmias. High resolution electro-anatomical mapping systems have become fundamental to perform these procedures. Recently, interventional cardiac magnetic resonance (iCMR) has been proposed as an alternative for fluoroscopy to guide atrial flutter ablations. The clinical experience with iCMR and dedicated three-dimensional mapping systems is growing. NorthStar is currently the first available vendor-neutral mapping system.
UNASSIGNED: We performed a real-time CMR-guided cavotricuspid isthmus (CTI) catheter ablation (CA) on a 69-year-old man using a novel mapping system (NorthStar Mapping System, Imricor Medical Systems, MN, USA). Starting from the CMR imaging, a pre-rendered segmentation model was loaded on NorthStar and used to guide the catheters, display voltage and activation maps, show mapping and ablation points. NorthStar can also take full control of the CMR scanner (i.e. start/stop sequences for anatomical information, tissue characterization, and catheter visualization) and communicate with the recorder/stimulator system (Advantage-MR EP, Imricor Medical Systems, MN, USA). With comparable procedural time to standard fluoroscopy-guided CA, CTI bidirectional block was achieved, without any complication.
UNASSIGNED: Using the NorthStar Mapping System, we managed to achieve a successful CMR-guided CTI ablation without any complication. Its further use should be explored, especially in more complex arrhythmias where a substrate-guided ablation is critical, as it could significantly improve results in terms of arrhythmia recurrence.

摘要：
■透视引导导管消融已成为治疗心律失常的金标准。高分辨率电解剖标测系统已经成为执行这些程序的基础。最近,介入性心脏磁共振（iCMR）已被提议作为透视检查的替代方法，以指导房扑消融。iCMR和专用三维标测系统的临床经验正在增长。NorthStar是目前第一个可用的供应商中立映射系统。
■我们使用新颖的标测系统（NorthStarMappingSystem，Imricor医疗系统，MN,美国）。从CMR成像开始，在NorthStar上加载了预渲染的分割模型，用于引导导管，显示电压和激活图，显示标测和消融点。NorthStar还可以完全控制CMR扫描仪（即解剖信息的开始/停止序列，组织表征，和导管可视化)并与记录器/刺激仪系统通信(Advantage-MREP,Imricor医疗系统，MN,美国）。手术时间与标准透视引导CA相当,实现了CTI双向阻断，没有任何并发症。
■使用NorthStar测绘系统，我们成功完成了CMR引导下的CTI消融,没有出现任何并发症.应探索其进一步用途,尤其是在更复杂的心律失常中，基质引导消融至关重要，因为它可以显着改善心律失常复发的结果。
