[Evaluation of XXXX using color Doppler echocardiography].

@entity1 @entity337
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 @entity337 , 44 @entity1 were examined consecutively. In 24 @entity1 , @entity337 was proven by angiography; in 20 @entity1 aortography revealed no regurgitation. Quantification of the severity of @entity337 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 @entity1 diagnostic images could be obtained with colour flow mapping Doppler echocardiography. With this method @entity337 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 @entity1 the difference was one grade. CONCLUSION: Colour flow mapping Doppler echocardiography is an important advance in the noninvasive preoperative diagnostics of @entity337 .
