Overview
The results of a variety of diagnostic studies can be integrated to assess or classify the severity of aortic insufficiency as shown in the table below.
ACC/AHA Guidelines- Classification of the Severity of Aortic Regurgitation in Adults (DO NOT EDIT) [1]
Indicator Mild Moderate Severe *Qualitative Angiographic grade 1+ 2+ 3-4+ Color Doppler jet Central jet, width less than 25% of LVOT Greater than mild but no signs of severe AR Central jet, width greater than 65% LVOT Doppler vena contracta width (cm) Less than 0.3 0.3-0.6 Greater than 0.6 *Quantitative (Cath or Echo) Regurgitant volume (ml/beat) Less than 30 30-59 Greater than or equal to 60 Regurgitant fraction (%) Less than 30 30-49 Greater than or equal to 50 Regurgitant orifice area (cm2) Less than 0.10 0.10-0.29 Greater than or equal to 0.30 *Additional Essential Criteria Left ventricular size Increased
AR = aortic regurgitation; cath = catheterization; echo = echocardiography; LVOT = left ventricular outflow tract.
