Purpose of Review

The field of transcatheter tricuspid valve interventions (TTVI) is rapidly evolving to meet a well-defined but unmet clinical need. Severe tricuspid regurgitation is common and is associated with significant morbidity and mortality. Surgical options are limited and of high risk. The success of TTVI depends on careful procedural planning, and cardiac computed tomography (CCT) plays an emerging key role.

Recent Findings

TTVI technologies have various targets, including the leaflets, annulus, and venae cavae, along with valve replacement. Based on the planned procedure, CCT allows for device sizing, careful assessment of the access route, and comprehensive analysis of relevant adjacent anatomic structures to enhance procedural safety. It can also evaluate right-sided heart function, and its data can be for fusion imaging and 3D printing.

Summary

Procedural planning is key to TTVI’s success and is highly dependent on high-quality CCT data. This review details the comprehensive roles of CCT, specifics of the dedicated TTVI protocol, and its limitations.

心脏计算机断层扫描在指导经导管三尖瓣介入治疗中的作用

审查目的

经导管三尖瓣介入 (TTVI) 领域正在迅速发展，以满足明确但未满足的临床需求。严重的三尖瓣反流很常见，并且与显着的发病率和死亡率相关。手术选择有限且风险高。TTVI 的成功取决于仔细的程序规划，而心脏计算机断层扫描 (CCT) 起着新兴的关键作用。

最近的发现

TTVI 技术有多种目标，包括瓣叶、瓣环和腔静脉，以及瓣膜置换术。根据计划的程序，CCT 允许设备尺寸、通路的仔细评估和相关相邻解剖结构的综合分析，以提高程序安全性。它还可以评估右侧心脏功能，其数据可用于融合成像和3D打印。

总结

程序规划是 TTVI 成功的关键，高度依赖于高质量的 CCT 数据。本综述详细介绍了 CCT 的综合作用、专用 TTVI 协议的细节及其局限性。
