Remote magnetic navigation (RMN) is as safe and effective as manual navigation for catheter ablation of ventricular arrhythmias. This case is the first description of a soft-tip ablation catheter entrapment in the mitral valve apparatus during an RMN ablation procedure. The tight knot created by the catheter around a mitral valve chordae required surgical removal. This complication, which has never been reported before, highlights the need for closer fluoroscopic monitoring when performing catheter loops inside the ventricles when using the RMN system.
远程磁导航（RMN）在室性心律失常导管消融方面与手动导航一样安全有效。本病例首次描述了在RMN消融过程中软头消融导管被困在二尖瓣装置中。导管在二尖瓣腱索周围形成的紧密结需要手术移除。这种以前从未报道过的并发症凸显了在使用RMN系统在心室内进行导管环操作时加强透视监测的必要性。
