51 consecutive patients with the clinical signs of aortic valve incompetence (AI) were evaluated by color-coded Doppler flow mapping (CDF) before angiography (AG). Quantitation of the severity of AI was performed by measurement of length and width of the extension of regurgitant jet (grade I-IV). After AG results both -AG and CDF- were compared. In 36 patients the results of both methods concurred exactly by use length in CDF. With CDF, the regurgitation was overestimated in 7 cases by one grade and underestimated in 8 patients also by one grade. Width of regurgitant jet relative to size of outflow space is a useful parameter to distinguish between mild and severe A1 (limit 0.50).
CDF is a suitable method for semiquantitative assessment of AI. In presence of unequivocal CDF signs and in consideration of clinical and other patients findings AG will be dispensable before aortic valve replacement.
对51例有主动脉瓣关闭不全（AI）临床体征的连续患者在血管造影（AG）前采用彩色编码多普勒血流图（CDF）进行评估。通过测量反流束延伸的长度和宽度（I-IV级）对AI的严重程度进行定量。AG结果出来后，将AG和CDF两者的结果进行比较。在36例患者中，两种方法的结果通过CDF中的长度测量完全一致。使用CDF时，7例患者的反流被高估一级，8例患者的反流被低估一级。反流束宽度相对于流出道空间大小是区分轻度和重度AI的一个有用参数（界限为0.50）。
CDF是AI半定量评估的一种合适方法。在存在明确的CDF征象且考虑临床及其他患者检查结果的情况下，在主动脉瓣置换术前AG将是不必要的。
