Tricuspid regurgitation is a commonly encountered condition, but precise methods of measuring its severity await development. The purpose of this review is to propose 29 echocardiographic and Doppler considerations that can be applied to gain a qualitative impression of the "significance or severity" of this regurgitant lesion. These methods evaluate the right heart chambers, the morphology of the valve, regurgitant Doppler flow signals, and forward flow. The proposed methods are based on echocardiographic techniques for evaluating mitral regurgitation. However, the literature on directly applying these considerations to judging the severity of tricuspid regurgitation is scant and caution is urged in applying them. One intended consequence of this review is to identify understudied features of tricsupid regurgitation so that those engaged in echocardiographic clinical investigation may be stimulated to develop the tools needed for its ultimate quantitation.
三尖瓣反流是一种常见病症，但精确测量其严重程度的方法仍有待开发。本综述的目的是提出29项超声心动图和多普勒相关考量因素，可用于对这种反流性病变的“重要性或严重程度”形成定性印象。这些方法评估右心腔、瓣膜形态、反流多普勒血流信号和前向血流。所提出的方法基于评估二尖瓣反流的超声心动图技术。然而，直接将这些考量因素用于判断三尖瓣反流严重程度的文献较少，应用时需谨慎。本综述的一个预期结果是确定三尖瓣反流尚未充分研究的特征，以便激发从事超声心动图临床研究的人员开发其最终定量所需的工具。
