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.
本研究描述了一种基于主动脉反流束速度时间积分与横截面积乘积来评估主动脉反流严重程度的多普勒超声心动图方法。该方法被发现对主动脉反流的血管造影分级具有很高的诊断效能，且分级之间的重叠最小。
