Calculation of Regurgitant Volume and RF using PVL orifice area | ||
|---|---|---|
Anterior PVL | Posterior PVL | |
PVL orifice area [cm2] | 0.24 | 0.24 |
VTI of PVL [cm] | 191 ± 0.59 | 192 ± 0.36 |
Regurgitant Volume [ml/beat] | 46 ± 0.14 | 46 ± 0.09 |
Outflow tract area [cm2] | 3.14 | 3.14 |
VTILVOT [cm] | 35 ± 0.47 | 35 ± 0.15 |
SVLVOT [ml/beat] | 111 ± 1.5 | 111 ± 0.42 |

Calculation of Regurgitant Volume and RF using the set CO | ||
Anterior PVL | Posterior PVL | |
set CO [L/min] | 3 | 3 |
HR [bpm] | 45 | 45 |
SVCIRC [ml/beat] = 3.0 L/45 bpm | 66.7 | 66.7 |
SVLVOT [ml/beat] | 111 ± 1.5 | 111 ± 0.42 |
Regurgitant Volume [ml/beat] = SVLVOT − SVCIRC | 44 ± 1.5 | 44 ± 0.42 |
