To study the prevalence and the characteristics of physiological valve regurgitation.
Pulsed wave Doppler echocardiography, continuous wave Doppler echocardiography and Doppler colour flow mapping were performed prospectively in healthy volunteers.
Echocardiography laboratory in a city hospital.
32 consecutive healthy volunteers (age 21-49 years, mean age 29.4).
Identification of regurgitation with colour Doppler flow mapping and measurement of the jet area, jet length, and maximal velocity of the regurgitation.
Regurgitation was recorded at the pulmonary (100%), tricuspid (100%), mitral (56%), and aortic valves (6%). The velocity of pulmonary and tricuspid regurgitation was similar to that predicted from the pressure gradient calculated from the Bernoulli equation. The jet area and jet length were generally small.
Trivial regurgitation from the pulmonary, tricuspid, and mitral valves is common in healthy people. It is important to take such regurgitation into account when valve disease is diagnosed.
研究生理性瓣膜反流的发生率及特点。
对健康志愿者前瞻性地进行脉冲波多普勒超声心动图、连续波多普勒超声心动图及彩色多普勒血流显像检查。
城市医院的超声心动图实验室。
32例连续入选的健康志愿者（年龄21 - 49岁，平均年龄29.4岁）。
用彩色多普勒血流显像识别反流，并测量反流束面积、反流束长度及反流最大速度。
在肺动脉瓣（100%）、三尖瓣（100%）、二尖瓣（56%）和主动脉瓣（6%）记录到反流。肺动脉瓣和三尖瓣反流速度与根据伯努利方程计算的压力阶差所预测的速度相似。反流束面积和长度通常较小。
健康人群中肺动脉瓣、三尖瓣和二尖瓣轻度反流很常见。在诊断瓣膜疾病时考虑到这种反流很重要。
