Inferior vena cava (IVC) filters are increasingly used in patients with recurrent venous thromboembolism in whom anticoagulation is contraindicated or intolerable. Migration of fragments is a known complication of IVC filter use. We present a case of a 32-year-old man, who presented with right-sided chest pain believed to be caused by a migrated IVC fragment to the right ventricle. The filter was removed by an endovascular cook forceps with the assistance of intracardiac echocardiography. This case serves as an addition to the existing reports of successful removal of intracardiac fragments via minimally invasive endovascular approach, amid a larger number of intracardiac fragments that have been removed by an open-heart approach.
下腔静脉（IVC）滤器越来越多地用于抗凝治疗禁忌或无法耐受的复发性静脉血栓栓塞患者。滤器碎片迁移是IVC滤器使用的一种已知并发症。我们报告一例32岁男性患者，其因IVC碎片迁移至右心室而出现右侧胸痛。在心脏内超声心动图的辅助下，通过血管内库克钳取出了滤器。在大量通过心脏直视手术取出的心脏内碎片中，该病例补充了现有通过微创血管内方法成功取出心脏内碎片的报告。
