Inferior vena cava filters are commonly used to prevent pulmonary embolism in patients who manifest deep vein thrombosis and recurrent pulmonary embolism despite anticoagulation, or in patients with contraindications to anticoagulation. We report the case of a 69-year-old man with a structurally normal heart who experienced migration of an inferior vena cava filter to the right ventricle, which caused the abrupt onset of recurrent episodes of nonsustained ventricular tachycardia unresponsive to intravenous antiarrhythmic medication. Cardiac imaging revealed the location of the filter within the right ventricle, and the device was removed, with subsequent resolution of the arrhythmia. We anticipate that the incidence of inferior vena cava filter migration might increase in the future because of recent changes in device construction. The sudden appearance of nonsustained ventricular tachycardia in a patient with an inferior vena cava filter might indicate the occurrence of this potentially life-threatening sequela and should lead to emergent cardiac imaging.
下腔静脉滤器常用于预防尽管接受了抗凝治疗仍发生深静脉血栓形成和复发性肺栓塞的患者，或有抗凝治疗禁忌证的患者。我们报告一例69岁男性病例，其心脏结构正常，但下腔静脉滤器迁移至右心室，导致反复发生非持续性室性心动过速，静脉注射抗心律失常药物无效。心脏成像显示滤器位于右心室内，随后取出该装置，心律失常随之缓解。我们预计，由于近期装置构造的变化，未来下腔静脉滤器迁移的发生率可能会增加。下腔静脉滤器患者突然出现非持续性室性心动过速可能提示这种潜在危及生命的后遗症的发生，应立即进行心脏成像检查。
