Diastolic assessment with a left ventricular assist device
Explore the dedicated LV assist device (LVAD) pathway, with its own measurement inputs and source qualifications.
Method
2025 ASE Table 7 · Doppler, right-heart pressure and interatrial septal position
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
Mitral E/A ratio
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.
Right atrial pressure mmHg
Contemporaneous cuff or invasive value
- Use a pressure obtained in the same hemodynamic state as the echo.
- Confirm the value is entered in mmHg.
- Do not mix values acquired under different loading conditions.
PASP mmHg
Contemporaneous cuff or invasive value
- Use a pressure obtained in the same hemodynamic state as the echo.
- Confirm the value is entered in mmHg.
- Do not mix values acquired under different loading conditions.
Average E/e′
PW tissue Doppler at the mitral annulus
- Place the sample at the septal or lateral mitral annulus.
- Use tissue-Doppler settings and align with annular motion.
- Measure the early diastolic e′ peak and average representative beats.
Septal E/e′
PW tissue Doppler at the mitral annulus
- Place the sample at the septal or lateral mitral annulus.
- Use tissue-Doppler settings and align with annular motion.
- Measure the early diastolic e′ peak and average representative beats.
LA volume index mL/m²
Enter the measured value in the displayed unit
- Confirm the variable matches the selected formula.
- Use the unit displayed beside the field.
- Keep measurements from the same representative hemodynamic state.
Interatrial septum
Enter the measured value in the displayed unit
- Neutral
- Bulges right
- Bulges left
- Confirm the variable matches the selected formula.
- Use the unit displayed beside the field.
- Keep measurements from the same representative hemodynamic state.
