Assessment of mitral valve anatomy according to the Wilkins score⁶⁴

Grade	Mobility	Thickening	Calcification	Subvalvular Thickening
1	Highly mobile valve with only leaflet tips restricted	Leaflets near normal in thickness (4-5 mm)	A single area of increased echo brightness	Minimal thickening just below the mitral leaflets
2	Leaflet mid and base portions have normal mobility	Midleaflets normal, considerable thickening of margins (5-8 mm)	Scattered areas of brightness confined to leaflet margins	Thickening of chordal structures extending to one-third of the chordal length
3	Valve continues to move forward in diastole, mainly from the base	Thickening extending through the entire leaflet (5-8mm)	Brightness extending into the mid-portions of the leaflets	Thickening extended to distal third of the chords
4	No or minimal forward movement of the leaflets in diastole	Considerable thickening of all leaflet tissue (>8-10mm)	Extensive brightness throughout much of the leaflet tissue	Extensive thickening and shortening of all chordal structures extending down to the papillary muscles
The total score is the sum of the four items and ranges between 4 and 16.

Recommendations for data recording and measurement in routine use for mitral stenosis quantitation

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