With the ongoing intravenous drug abuse (IVDA) epidemic, the number of IVDA patients with infective endocarditis is increasing. These cases are often characterized by large vegetations complicated by valvular dysfunction, heart failure, and recurrent septic pulmonary emboli demanding surgical intervention. Latter cannot be offered in a good proportion of the patients due to challenging medical and social complexities. Hence, AngioVac system has been used as an alternative therapy; however, it is associated with high procedural mortality. In this document, we describe in detail the successful treatment of a case of large tricuspid valve vegetation, with prohibitive risk for surgery, using a percutaneous catheter-based system, the Triever aspiration catheter with FLEX technology, with the guidance of intracardiac echocardiogram.

新型心内超声心动图引导导管去除不能手术的三尖瓣赘生物

随着持续的静脉药物滥用 (IVDA) 流行，IVDA 感染性心内膜炎患者的数量正在增加。这些病例的特征通常是大的赘生物并发瓣膜功能障碍、心力衰竭和复发性脓毒性肺栓塞，需要手术干预。由于具有挑战性的医疗和社会复杂性，不能在很大比例的患者中提供后者。因此，AngioVac 系统已被用作替代疗法；然而，它与高手术死亡率有关。在本文档中，我们详细描述了在心内超声心动图的指导下，使用基于经皮导管的系统、采用 FLEX 技术的 Triever 抽吸导管成功治疗了一例大型三尖瓣赘生物，手术风险高。
