LV Diastolic Function (ASE 2016, normal EF)

ASE/EACVI 2016 LV diastolic function screen for normal EF: four criteria (average E/e' > 14, septal e' < 7 or lateral e' < 10 cm/s, TR velocity > 2.8 m/s, LA volume index > 34 mL/m2).

Example

Average E/e'
16
Septal e' velocity
6
Peak TR velocity
3.0
LA volume index
40

Result: Diastolic dysfunction (4 of 4 criteria abnormal).

The tool opens with these values already filled in. Replace them with your own.

What the result means

Result
of the criteria measured: < 50% abnormal = normal, > 50% = diastolic dysfunction, exactly 50% = indeterminate. Grade I-III (mitral E/A) not computed here.

What you enter

  • Average E/e' (abnormal > 14)
  • Septal e' velocity (cm/s; abnormal < 7)
  • Lateral e' velocity (cm/s; abnormal < 10)
  • Peak TR velocity (m/s; abnormal > 2.8)
  • LA volume index (mL/m2; abnormal > 34)
How this is calculated
Criteria
four items, each abnormal if: average E/e′ > 14; septal e′ < 7 or lateral e′ < 10 cm/s; TR velocity > 2.8 m/s; LA volume index > 34 mL/m2 (strict inequalities).
