Assessment of tricuspid valve (TV) function plays an important role in a number of clinical disease states, including left-sided valve disease and heart failure. However, the TV is a complex structure that, unlike the aortic and mitral valve, it is not possible to visualize in one cross-sectional view using either transthoracic or transoesophageal two-dimensional echocardiography (i.e. imaging all three TV leaflets and their attachment in the annulus simultaneously). Conversely, three-dimensional echocardiography allows users to visualize the whole TV apparatus from any perspective. This may significantly improve our understanding of the pathophysiological mechanisms underlying the various TV diseases and functional tricuspid regurgitation, and potentially suggest ways to improve surgical treatment. This review details the current status of real-time three-dimensional echocardiography evaluation of TV morphology and function with its clinical applications and limitations.
三尖瓣（TV）功能评估在包括左侧瓣膜疾病和心力衰竭在内的多种临床疾病状态中起着重要作用。然而，三尖瓣是一个复杂的结构，与主动脉瓣和二尖瓣不同，使用经胸或经食管二维超声心动图在一个横截面视图中无法可视化（即同时成像所有三个三尖瓣叶及其在瓣环中的附着情况）。相反，三维超声心动图允许用户从任何角度可视化整个三尖瓣装置。这可能会显著提高我们对各种三尖瓣疾病和功能性三尖瓣反流潜在病理生理机制的理解，并有可能提出改善手术治疗的方法。本综述详细介绍了实时三维超声心动图评估三尖瓣形态和功能的现状及其临床应用和局限性。
