三尖瓣环（TA）评估仍然是手术决策过程中的一个主要问题。显然，二维经胸超声心动图（2D TTE）由于其复杂的三维形状，在TA可视化方面受到限制。本研究旨在利用实时三维超声心动图（RT3DE）测定40例患者TA的形态、大小和功能，并将其分为两组（ⅰ组TA正常，ⅱ组TA扩张）。二维TTE测量包括顶端4室（AP4CH） TA直径（TAD）和胸骨旁短轴（PSAX）视图。RT3DE测量包括TA面积（TAA）、主要TAD和次要TAD。TA分数缩短（TAFS）和TA分数面积变化（TAFAC）通过收缩末期和舒张末期测量计算。RT3DE可以显示和测量所有患者的整个椭圆形TA，而不管TA的大小（正常或扩张）。在AP4CH和PSAX视图上2D TTE测量的TAD均明显小于RT3DE测量的主要TAD (P
Tricuspid annulus (TA) evaluation continues to be a major problem in the surgical decision-making process. Obviously, 2-dimensional transthoracic echocardiography (2D TTE) is limited in TA visualization due to its complex 3D shape. The study aimed to determine TA morphology, size and function with real-time three-dimensional echocardiography (RT3DE) in 40 patients divided into two equal groups (I: normal TA and II: dilated). 2D TTE measurements included TA diameter (TAD) at apical 4-chamber (AP4CH) and parasternal short axis (PSAX) views. RT3DE measurements included TA area (TAA), major TAD and minor TAD. TA fractional shortening (TAFS), and TA fractional area change (TAFAC) were calculated from end-systolic and end-diastolic measurements. RT3DE allowed visualization and measurement of the entire oval-shaped TA in all patients irrespective of its size (normal or dilated). 2D TTE measurement of TAD at both AP4CH and at PSAX views was significantly smaller than the major TAD measured by RT3DE (P
