title: Assessment of aortic regurgitation by color flow and continuous-wave Doppler echocardiography.
abstract: This study describes a Doppler echocardiographic method for assessing the severity of aortic regurgitation based on the product of the velocity time integral and cross-sectional area of the aortic regurgitation jet. This method was found to be highly productive of the angiographic grade of aortic regurgitation with minimal overlap between grades.
