Abstract：
UNASSIGNED: There is a close relationship between volumes of the right atrium (RA) and dimensions and derived functional sphincter-like features of the tricuspid annulus (TA). However, its relation to longitudinal TA motion is not clear, which can even be considered to be a characteristic of the longitudinal shortening of the right ventricle (RV) and represented by TA plane systolic excursion (TAPSE). Therefore, the aim of this cohort study was to perform a detailed analysis of the relationship of three-dimensional speckle-tracking echocardiography (3DSTE)-derived RA volumes and RV longitudinal shortening in healthy individuals. These parameters were also examined in case of average values and larger/smaller than mean values.
UNASSIGNED: The present study comprised 93 healthy adults (mean age: 27.7±6.3 years, 46 men), who participated in a complete medical investigation including two-dimensional, TAPSE, Doppler and 3DSTE-derived RA volumetric echocardiographic assessments.
UNASSIGNED: RA volumes, stroke volumes and emptying fractions were not related to TAPSE. In case of low, mean and high TAPSE, maximum [50.4±22.4 vs. 49.5±15.5 vs. 49.0±15.8 mL, P= not significant (ns)], preatrial contraction (36.9±16.8 vs. 34.5±10.4 vs. 35.6±10.5 mL, P= ns) and minimum (28.7±13.6 vs. 27.2±9.4 vs. 26.6±9.3 mL, P= ns) RA volumes did not differ. Higher RA volumes showed no associations with TAPSE either.
UNASSIGNED: 3DSTE-derived RA volumes and M-mode echocardiography-derived TAPSE representing RV longitudinal shortening are not associated in healthy adults. None of the RA volumes showed correlations with TAPSE.

摘要：
■右心房（RA）的体积与三尖瓣环（TA）的尺寸和衍生的功能性括约肌样特征之间存在密切的关系。然而,它与纵向TA运动的关系尚不清楚，这甚至可以被认为是右心室（RV）纵向缩短的特征，并由TA平面收缩偏移（TAPSE）表示。因此,本队列研究的目的是详细分析健康个体中三维斑点追踪超声心动图(3DSTE)衍生的RA体积与RV纵向缩短的关系.在平均值和大于/小于平均值的情况下也检查这些参数。
■本研究包括93名健康成年人（平均年龄：27.7±6.3岁，46名男子），他参加了包括二维在内的完整医学调查，TAPSE,多普勒和3DSTE衍生的RA容积超声心动图评估。
■RA卷，每搏量和排空分数与TAPSE无关.在低的情况下，平均和高TAPSE，最大值[50.4±22.4vs.49.5±15.5vs.49.0±15.8mL,P=不显著(ns)]，心房前收缩(36.9±16.8vs.34.5±10.4vs.35.6±10.5mL,P=ns)和最小值(28.7±13.6vs.27.2±9.4vs.26.6±9.3mL,P=ns)RA体积没有差异。较高的RA体积也与TAPSE无关联。
■3DSTE衍生的RA体积和M型超声心动图衍生的代表右心室纵向缩短的TAPSE在健康成人中不相关。RA体积均未显示与TAPSE的相关性。
