BSE normal reference tables
RV size, function & RA
BSE normal reference ranges — RV size
Normal values for RV size (apical 4-chamber RV-focused; RVOT from PSAX). Only upper/lower normal limits are published.
| Parameter | Male | Female |
|---|---|---|
| RVD1 basal diameter (mm) | 26–47 | 22–43 |
| RVD2 mid diameter (mm) | 19–42 | 17–35 |
| RVD3 length (mm) | 55–87 | 51–80 |
| RVOT proximal (mm) | 24–44 | 20–42 |
| RVOT distal (mm) | 16–29 | 14–28 |
| RVED area indexed (cm²/m²) | ≤13.6 | ≤12.6 |
BSE normal reference ranges — RV function & right atrium
RV function and right atrial size. FAC, RV S' and RA area normal limits. TAPSE lower limit of normal ≥17 mm (ASE).
| Parameter | Male | Female |
|---|---|---|
| Fractional area change FAC (%) | ≥30 | ≥35 |
| RV S' (cm/s) | ≥9 | ≥9 |
| TAPSE (mm) | ≥17 | ≥17 |
| RA area (cm²) | ≤22 | ≤19 |
| RA area indexed (cm²/m²) | ≤11 | ≤11 |
