Mitral Valve Analysis

MV Score

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