Calculate Severity of Diastolic Dysfunction on TTE

Diastolic Dysfunction Grader

Start with e’, then use mitral inflow and filling pressure markers to grade severity.

1

Septal e’

Is septal e’ ≤ 6 cm/s?

2

Mitral inflow

Select the E/A pattern.

3

E/e’

Is E/e’ elevated?

4

TR velocity / RVSP

Is TR velocity elevated?

Optional

Supportive markers

Use these when the core data are discordant or borderline.

Result

Select inputs above

Start with septal e’. If e’ is normal, diastolic function is usually normal. If e’ is low, use E/A pattern and filling pressure markers.
