Dr Antoine Micheau , CHU ARNAUD DE VILLENEUVE , Montpellier , Herault , FRANCE

Major criteria:

Regional RV akinesia or dyskinesia or dyssynchronous RV contraction

And 1 of the following:

- Ratio of RV end-diastolic volume to BSA ≥110 mL/m2 (male) or ≥ 100 mL/m2 (female)

- or RV ejection fraction ≤ 40%

 

Minor criteria:

Regional RV akinesia or dyskinesia or dyssynchronous RV contraction

And 1 of the following:

- Ratio of RV end-diastolic volume to BSA ≥100 mL/m2 to < 110 mL/m2 (male) or ≥ 90 mL/m2 to < 100 mL/m2 (female)

- or RV ejection fraction > 40% to ≤ 45%
