Mitral Valve

Mitral stenosis - routine measurements

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

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 shortening)

Mitral valve stenosis - Wilkins score

Assessment of mitral valve anatomy according to the Wilkins scoreWilkins

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.

Tricuspid Valve

Tricuspid stenosis - severity

Findings indicative of haemodynamically significant tricuspid stenosisASEVS

Specific findings
Mean pressure gradient	≥5 mmHg
Inflow time-velocity integral	>60 cm
T1/2	≥190 ms
Valve area by continuity equationa	≤1 cm2
Supportive findings
Enlarged right atrium ≥moderate
DHated inferior vena cava
aStroke volume derived from left or right ventricular outflow. In the presence of more than mild TR, the derived valve area will be underestimated. Nevertheless, a value ≤1 cm2 implies a significant haemodynamic burden imposed by the combined lesion.
