BACKGROUND
Tricuspid annulus (TA) geometry and function reference values are limited, especially for Asian populations. We aimed to explore TA using four-dimensional echocardiography (4DE) in a healthy Asian population.
METHODS
A total of 355 healthy Asian volunteers (median age 34 years; 52% males) were prospectively enrolled. TA geometry and function were analyzed using 4DE throughout the cardiac cycle.
RESULTS
The TA area, perimeter, and dimensions were smallest at end systole (ES) and largest at late diastole (LD). Normal TA parameters at end diastole (ED) in different sex and age groups were obtained. TA areas, perimeters, and dimensions in males were significantly larger than those in females at ED; BSA-indexed perimeters and BSA-indexed dimensions in males were significantly smaller than those in females at ED. TA parameters correlated well with tricuspid valve (TV) tenting, right ventricle (RV), and right atrium (RA) parameters.
CONCLUSIONS
Reference values of TA parameters were obtained by 4DE in an Asian population. Quantitative data on TA geometry and function are essential for TA pathology and therapeutics.
背景
三尖瓣环（TA）的几何形状和功能参考值有限，特别是对于亚洲人群。我们旨在使用四维超声心动图（4DE）探索健康亚洲人群的 TA。
方法
共前瞻性纳入 355 名健康的亚洲志愿者（中位年龄 34 岁；52%为男性）。使用 4DE 分析整个心动周期的 TA 几何形状和功能。
结果
TA 面积、周长和尺寸在收缩末期（ES）最小，在舒张晚期（LD）最大。获得了不同性别和年龄组舒张末期（ED）正常 TA 参数。ED 时男性的 TA 面积、周长和尺寸明显大于女性；ED 时男性的 BSA 指数化周长和 BSA 指数化尺寸明显小于女性。TA 参数与三尖瓣（TV）幕、右心室（RV）和右心房（RA）参数密切相关。
结论
通过 4DE 在亚洲人群中获得了 TA 参数的参考值。TA 几何形状和功能的定量数据对于 TA 病理学和治疗至关重要。
