## Method

Compare current mean gradient, DVI and EOA with a stable postimplant baseline

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

### Comparison

Enter the measured value in the displayed unit

- TAVI · change from baseline
- Bioprosthesis · hemodynamic deterioration
- Confirm the variable matches the selected formula.
- Use the unit displayed beside the field.
- Keep measurements from the same representative hemodynamic state.

### Baseline mean gradient  mmHg

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.

### Current mean gradient  mmHg

Enter the measured value in the displayed unit
