title: Percutaneous Extraction of Embolized Intracardiac Inferior Vena Cava Filter Struts Using Fused Intracardiac Ultrasound and Electroanatomic Mapping.
abstract: 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.
