Colour flow mapping Doppler echocardiography is a new, noninvasive method for studying the direction and velocity of blood flow within the cardiac chambers. In order to estimate the sensitivity and specificity of this method in the evaluation of aortic regurgitation, 44 patients were examined consecutively. In 24 patients, aortic valve incompetence was proven by angiography; in 20 patients aortography revealed no regurgitation. Quantification of the severity of aortic insufficiency was performed by grading the amount of colour of the regurgitant flow (grade I-IV) and comparing it with the angiographic data. In 43 out of 44 patients diagnostic images could be obtained with colour flow mapping Doppler echocardiography. With this method aortic insufficiency was detected in all cases (sensitivity 100%). The specificity was 97% (one false positive diagnosis). For quantification of the severity of regurgitation agreement with the angiographic findings was obtained in 18 out of 24 cases. In the remaining 6 patients the difference was one grade.
Colour flow mapping Doppler echocardiography is an important advance in the noninvasive preoperative diagnostics of aortic incompetence.
彩色血流图多普勒超声心动图是一种用于研究心腔内血流方向和速度的新型非侵入性方法。为了评估该方法在主动脉瓣反流评估中的敏感性和特异性，对44例患者进行了连续检查。24例患者经血管造影证实存在主动脉瓣关闭不全；20例患者主动脉造影显示无反流。通过对反流血流的颜色量进行分级（I-IV级）并与血管造影数据进行比较，对主动脉瓣关闭不全的严重程度进行量化。44例患者中有43例通过彩色血流图多普勒超声心动图获得了诊断图像。用该方法在所有病例中均检测到主动脉瓣关闭不全（敏感性100%）。特异性为97%（1例假阳性诊断）。在24例病例中有18例对反流严重程度的量化与血管造影结果一致。其余6例患者的差异为1个等级。
彩色血流图多普勒超声心动图是主动脉瓣关闭不全非侵入性术前诊断的一项重要进展。
