彩色多普勒血流显像半定量左心瓣膜返流与造影相关性研究

A CORRELATIVE STUDY ON S EM [QUANTIT- ATIVE GRADING OF LEFT-SIDE VALV- ULAR REGURGITATION BY CDFI AND CARDIOANGIOCRAPHY

本文在78例慢性左心瓣膜病变患者中比较了彩色多普勒血流显像(CDFI)和左心系统造影两项检查的结果。其中10例左室和升主动脉造影、7例左室造影、60例升主动脉造影。统计学采用Spearman等级相关。结果发现:在17例左室造影诊断二尖瓣返流中,CDFI与造影的等级相关系数γ为0.74(P<0.05);在70例升主动脉造影诊断主动脉瓣返流中,CDFI与造影的等级相关系数γ为0.82(P<0.01)。结论:CDFI半定量诊断左心瓣膜返流具有与造影相似的准确性。

The semiquantitative grading results for assessing the sevesity of leftside valvular regurgitation in 78 patients by using CDFI and cardioangiography were compared and analysed for Spearman grade correlation. The cardi-oangiograms included 10 left ventricle and ascending aorta ( LV and AO ) , 7 LV and 60 AO. It was revealed that the correlation between CDFI and cardioangiography was 0.74 ( P<0.05) in mitral regurgitation and 0.82 (P<0.01) in aortic regurgitation. It can be concluded that CDFI is as accurate as cardioangiography for quantifying the severity of left-side valvular regurgitation.
