目的：无论二尖瓣反流的严重程度如何，峰值收缩期二尖瓣环速度与左心室射血分数（EF）相关。收缩期三尖瓣环速度峰值（RV- sm）和三尖瓣环平面收缩偏移（TAPSE）用于评估右心室（RV） EF （RVEF）。我们研究了三尖瓣反流（TR）是否影响RV-Sm、TAPSE和RVEF之间的关系。方法：625例患者行超声心动图和多普勒组织检查。采用Simpson法则估计左室EF和RVEF。由于混淆，我们排除了影响二尖瓣环运动或左心室功能的疾病患者。我们最终招募了225例患者：125例轻度TR， 50例中度TR， 50例重度TR。40例研究患者（20例轻度TR， 10例中度TR， 10例重度TR）接受了放射性核素脑室造影。结果：辛普森法估测的RVEF与放射性核素法估测的RVEF相关性强(r = 0.793, r(2) = 0.629， P
Objectives: Peak systolic mitral annular velocities correlate with left ventricular ejection fraction (EF) regardless of mitral regurgitation severity. Peak systolic tricuspid annular velocity (RV-Sm) and tricuspid annular plane systolic excursion (TAPSE) are used to assess right ventricular (RV) EF (RVEF). We investigated whether tricuspid regurgitation (TR) affects the relationship among RV-Sm, TAPSE, and RVEF.Methods: Patients (n = 625) underwent echocardiography and Doppler tissue studies. Left ventricular EF and RVEF were estimated by Simpson's rule. Because of confounding, we excluded patients with diseases that influence mitral annular motion or left ventricular function. We finally enrolled 225 patients: 125 with mild TR, 50 with moderate TR, and 50 with severe TR. Forty study patients (20 with mild TR, 10 with moderate TR, and 10 with severe TR) received radionuclide ventriculography.Results: The RVEF estimated by Simpson's method correlated strongly to that estimated by the radionuclide method (r = 0.793, r(2) = 0.629, P
