The rapid development of transcatheter tricuspid valve intervention (TTVI) therapies has quickly provided the opportunity to improve patient selection and procedural planning for patients with significant tricuspid regurgitation (TR) considered at high surgical risk. This review focuses on the contributions which both computed tomography angiography and cardiac magnetic resonance can provide in the better understanding of the natural history of TR, in the comprehensive anatomical and functional assessment of right heart involvement and in the timing and planning for TTVI. We also discuss areas of potential importance such as the quantification of response to TTVI, which will be informative for future trials.

CT和MRI在三尖瓣关闭不全的治疗时机中的重要作用。

经导管三尖瓣介入治疗（TTVI）的快速发展迅速为改善具有高手术风险的三尖瓣关闭不全（TR）患者的选择和手术计划提供了机会。这项审查的重点是计算机断层扫描血管造影和心脏磁共振都可以在更好地了解TR的自然史，对右心脏受累的全面解剖和功能评估以及TTVI的时间和计划方面做出的贡献。我们还将讨论潜在的重要领域，例如对TTVI的反应进行量化，这将为以后的试验提供参考。
