Key result
Combining continuous wave and colour Doppler achieves ~85% agreement with angiography for grading aortic regurgitation.
Why the study?
Do continuous wave Doppler and colour Doppler accurately assess the severity of aortic regurgitation compared to angiography?
Population
80 patients with angiographically proven aortic regurgitation
Comparison
Continuous wave Doppler, colour Doppler, and… vs Angiography (invasive data)

Should not yet change aortic regurgitation grading practice; leaves open need for prospective validation in mixed valve disease.
Observational (n=80)
Do continuous wave Doppler and colour Doppler accurately assess the severity of aortic regurgitation compared to angiography?
Combining continuous wave and colour Doppler provides the highest agreement (85%) with angiography for grading aortic regurgitation, though accuracy decreases in the presence of aortic stenosis.
Wilkenshoff et al. (1994) conducted an observational in Aortic regurgitation (n=80). Continuous wave and colour Doppler echocardiography vs. Angiography was evaluated on Agreement with angiography in grading aortic regurgitation. Combining continuous wave and colour Doppler indices yielded 85% agreement with angiography for the semiquantitative evaluation of aortic regurgitation.
