•Data are expressed as mean ± SD (95% confidence interval). Note that for e´ velocity in subjects aged 16 to 20 years,
values overlap with those for subjects aged 21 to 40 years. This is because e´ increases progressively with age in children
and adolescents. Therefore, the e´ velocity is higher in a normal 20-year-old than in a normal 16-year-old, which results in
a somewhat lower average e´ value when subjects aged 16 to 20 years are considered.
•∗
Standard deviations are not included because these data were computed, not directly provided in the original articles
from which they were derived.

Mitral valve stenosis - Wilkins score

Recommendations for data recording and measurement in routine use for mitral stenosis quantitation[6]
Data element Recording Measurement
Planimetry
- 2D parasternal short-axis view - contour of the inner mitral orifice
- determine the smallest orifice by scanning
from apex to base
- include commissures when opened
- positioning of measurement plan can be
oriented by 3D echo
- in mid-diastole (use cine-loop)
- lowest gain setting to visualize the whole
mitral orifice
- average measurements if atrial fibrillation
Mitral flow
- continuous-wave Doppler - mean gradient from the traced contour of the
diastolic mitral flow
- apical windows often suitable (optimize
intercept angle)
- pressure half-time from the descending sLope of the
E-wave (mid-diastole slope if not linear)
- adjust gain setting to obtain well-defined
flow contour
- average measurements if atrial fibrillation
Systolic
pulmonary artery
pressure
- continuous-wave Doppler - maximum velocity of tricuspid regurgitant flow
- multiple acoustic windows to optimize
intercept angle
- estimation of right atrial pressure according to
inferior vena cava diameter
Valve anatomy
- parasternal short-axis view - valve thickness (maximum and heterogeneity)
- commissural fusion
- extension and location of localized bright zones
(fibrous nodutes or calcification)
- parasternal long-axis view - valve thickness
- extension of calcification
- valve pliability
- subvalvular apparatus (chordal thickening, fusion, or
shortening)
- apical two-chamber view - subvalvular apparatus (chordal thickening, fusion, or
