Diastolic assessment in mitral stenosis
Explore the dedicated filling-pressure pathway for mitral stenosis and review its acquisition guidance and sources.

2025 ASE Table 7 · IVRT, mitral A velocity and IVRT/T(E−e′)
Use the measurement units shown below. Some fields apply only to a selected method or condition; follow the interactive tool’s method choices. The interactive tool keeps missing measurements incomplete and provides its method-specific results and reference context.
Measurements and acquisition
IVRT ms
Spectral Doppler timing
- Use a sweep speed that clearly shows the interval boundaries.
- Measure from the specified onset to offset.
- Average representative beats using consistent rhythm handling.
Mitral A peak velocity m/s
PW Doppler at the mitral leaflet tips
- Place the PW sample between the mitral leaflet tips.
- Record at end-expiration with a clear E and A wave.
- Measure the requested peaks or trace the requested envelope.
IVRT / T(E−e′)
Spectral Doppler timing
- Use a sweep speed that clearly shows the interval boundaries.
- Measure from the specified onset to offset.
- Average representative beats using consistent rhythm handling.
