Normal and abnormal valves for measures of RV function in adult patients (ASE/ESC recommendations) (13).
| Parameter | Abnormality threshold |
|---|---|
| TAPSE (mm) | <17 |
| RV FAC (%) | <35 |
| RV free wall 2D strain (%) | ≥−20 |
| RV 3D EF (%) | <45 |
| Pulsed Doppler S wave (cm/s) | <9.5 |
EF, ejection fraction; FAC, fractional area change; RV, right ventricle; TAPSE, tricuspid annular plane systolic excursion.
