用彩色多普勒血流图(CDFI)检查122例风湿性心脏瓣膜病患者行二尖瓣和/或主动脉瓣人工瓣置换术加三尖瓣环缩术前后三尖瓣返流(TR)的变化.用收缩期TR的瞬时面积(TR-IA)分级,与彩色多普勒频谱测得的每搏返流容量(TR-SV)对照,发现TR-IA<2 cm2,2～4 cm2,4.1～10 cm2,>10 cm2时,TR-SV分别为0.814±0.23 ml,3.684±1.19 ml,8.67±3.06 ml,30.47±14.32 ml.本研究说明,CDFI探测TR是一种非侵入性的、敏感性高、特异性强的诊断方法.

The tricuspid regurgitation(TR)of 122 patients with rheumatic heart valvular diseases,whose mitral and/or aortic valve replacements and tricuspid annuloplasty were performed,were mea-sured by color Doppler flow imaging(CDFI)before and after operation.By comparing and analysing re-lationship between the instantaneous areas of TR(TR-IA)during systole and stroke volume of TR(TR-SV)calculated with color Doppler frequency spectra,we found that when the TR-IA was<2 cm2,2～4 cm2,4.1～10 cm2, >10 cm2,the TR-SV was 0.81±0.23 ml,3.68±1.19 ml,8.67±3.06 ml,30.47±14.32 ml,respectively.This study suggested that CDFI examination is a noninvasive high-sensi-tive and specific method for diagnosis of TR.
