This report describes the percutaneous extraction of embolized intracardiac inferior vena cava (IVC) filter struts using fluoroscopy and fused intracardiac echocardiography and three-dimensional electroanatomic mapping. Six patients with indwelling IVC filters placed at outside institutions 5 months to 14 years previously presented with cross-sectional imaging of the chest demonstrating fractured IVC filter struts embolized to the myocardial free wall (four patients) or interventricular septum (two patients). All embolized filter struts were successfully retrieved, and open heart surgery was avoided.
本报告描述了使用荧光透视、心脏内超声心动图融合以及三维电解剖标测经皮取出栓塞在心脏内的下腔静脉（IVC）滤器支柱的方法。6例患者，其IVC滤器于5个月至14年前在外部机构留置，胸部横断面成像显示IVC滤器支柱断裂并栓塞至心肌游离壁（4例患者）或室间隔（2例患者）。所有栓塞的滤器支柱均成功取出，避免了心脏直视手术。
