Aortic insufficiency classification of severity

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.

 * {| class="wikitable" border="1"

! Indicator !! Mild !! Moderate !! Severe AR = aortic regurgitation; cath = catheterization; echo = echocardiography; LVOT = left ventricular outflow tract.
 * *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
