Key result
Color Doppler detects significant acute aortic regurgitation with ~88% sensitivity versus electromagnetic flow.
Why the study?
A quantitative noninvasive method to evaluate acute aortic regurgitation using color Doppler flow needed validation against electromagnetic flow measurements.
Effect estimate: Sensitivity 88%, specificity 83%, predictive value 85%

Color Doppler may grade acute AR in dogs; leaves open human validation and clinical adoption.
Reeves et al. (1990) studied Acute aortic regurgitation (n=10). Color Doppler flow assessment vs. Aortic electromagnetic flow recordings was evaluated on Detection of significant (moderate + severe) aortic regurgitation (Sensitivity 88%, specificity 83%, predictive value 85%). Color Doppler flow assessment demonstrated 88% sensitivity, 83% specificity, and 85% predictive value for detecting significant acute aortic regurgitation compared to electromagnetic flow.
