Tricuspid regurgitation, either isolated or associated with left-valve disease, has a strong impact on outcome. Surgical treatment of tricuspid regurgitation has increased in recent years, but in-hospital mortality remains high probably due to the risk profile of the recipients. As a consequence, most of the patients with severe tricuspid regurgitation, especially if isolated, remain untreated. Transcatheter tricuspid valve interventions are rapidly spreading as alternative options to open-heart procedures fulfilling this important unmet need. Although patient selection and timing of intervention are unclear, many devices have been developed in recent years for both repair and replacement of tricuspid valve. Repair tools can be targeted to leaflets or annulus. Replacement devices include heterotopic and orthotropic systems. The aim of this review is to report possible indications and summarize current data about the different devices available for transcatheter tricuspid valve interventions.

三尖瓣关闭不全，单独发生或与左瓣疾病相关，对结局有很大影响。近年来，三尖瓣关闭不全的手术治疗有所增加，但由于接受者的风险状况，院内死亡率仍然很高。结果，大多数患有严重三尖瓣关闭不全的患者，尤其是孤立的患者，仍未得到治疗。经导管三尖瓣介入术正在迅速普及，作为满足这一重要未满足需求的心脏直视手术的替代选择。尽管尚不清楚患者的选择和介入时机，但近年来已开发出许多装置来修复和更换三尖瓣。维修工具可以针对小叶或瓣环。更换装置包括异位和正交异性系统。这篇综述的目的是报告可能的适应症并总结可用于经导管三尖瓣介入治疗的不同设备的当前数据。
