In this article we show the morphologic detail of the tricuspid valve (TV) apparatus and discuss the spectrum of diagnostic information that CT and MRI can provide regarding pathologic processes. We also compare the strengths and limitations of these modalities with currently established echocardiographic diagnostic parameters.
The TV plays an important role in a number of pathologic states, and its abnormality can directly or indirectly influence morbidity and mortality in different cardiac disorders. However, the importance of the role of the TV has been overlooked primarily because TV malfunction may remain less symptomatic for a long time. Along with rapid development in imaging technology, improvement in postoperative management, and better understanding of the pathophysiologic mechanisms of TV dysfunction, more attention is being given to careful imaging analysis of this "forgotten valve."

TV 在多种病理状态中起着重要作用，其异常可直接或间接影响不同心脏疾病的发病率和死亡率。然而，TV 功能障碍的重要性主要被忽视，因为 TV 功能障碍可能在很长一段时间内症状不明显。随着影像学技术的快速发展、术后管理的改善以及对 TV 功能障碍病理生理机制的更好理解，人们越来越关注对这一“被遗忘的瓣膜”进行仔细的影像学分析。
