Key result
Two-dimensional Doppler echocardiographic indexes of regurgitant aortic valvular area correlated strongly with angiographic grading of aortic regurgitation severity (r=0.88; p<0.001).
Why the study?
Does two-dimensional Doppler echocardiographic measurement of RAVA and AVOA accurately assess the presence and severity of aortic regurgitation compared to aortography?

Supports noninvasive Doppler echocardiography for aortic regurgitation grading; leaves open prospective outcome validation before practice change.

Does two-dimensional Doppler echocardiographic measurement of RAVA and AVOA accurately assess the presence and severity of aortic regurgitation compared to aortography?
Effect estimate: r = 0.88
p-value: p=<0.001
Two-dimensional Doppler echocardiographic indexes, specifically the RAVA/AVOA ratio, provide a highly sensitive and specific non-invasive method for grading the severity of aortic regurgitation that correlates well with angiography.
Veyrat et al. (1983) conducted a cross-sectional in Aortic regurgitation (n=95). Two-dimensional pulsed Doppler echocardiography vs. Angiography was evaluated on Correlation of RAVA and RAVA/AVOA indexes with angiographic grading (r = 0.88, p=<0.001). Two-dimensional Doppler echocardiographic indexes of regurgitant aortic valvular area correlated strongly with angiographic grading of aortic regurgitation severity (r=0.88; p<0.001).
