The tricuspid valve is, in fact, anatomically and functionally more complex than its left-sided counterpart-the mitral valve. Patients may develop tricuspid regurgitation from a variety of mechanisms. While current guidelines provide a very basic approach to tricuspid regurgitation (TR) evaluation, more recent techniques, particularly 3D echocardiography, have provided novel insights into how we can ascertain the mechanism and severity of tricuspid regurgitation, how the tricuspid valve adapts to disease and, importantly, how we assess the effects of TR on right ventricular size and function. We anticipate that these advances will soon yield dividends that will help us decide on approaches to treatment and timing of surgery.
事实上，三尖瓣在解剖结构和功能上比其左侧对应物——二尖瓣更为复杂。患者可能通过多种机制发生三尖瓣反流。虽然当前指南提供了一种非常基本的三尖瓣反流（TR）评估方法，但更新的技术，特别是三维超声心动图，为我们如何确定三尖瓣反流的机制和严重程度、三尖瓣如何适应疾病，以及重要的是，我们如何评估三尖瓣反流对右心室大小和功能的影响提供了新的见解。我们预计这些进展很快将产生成效，帮助我们决定治疗方法和手术时机。
