Table 6. Relative error in simulation vs measurement (in %) in the validation group.
First and second line in each subject for measured flow in ascending, descending aorta, respectively. MP, mean ventricular pressure; SV, stroke volume; Ew, external work; A-V coupling, arterio-ventricular coupling; CE, cardiac efficiency.
| Patient | measurement type | MP | SV | Ew | V-A coupling | CE |
|---|---|---|---|---|---|---|
| Patient 1 | ascending aorta | 10 | 6 | 2 | 6 | 4 |
| descending aorta | 5 | 3 | 5 | 6 | 4 | |
| Patient 2 | ascending aorta | 2 | 3 | 3 | 2 | 10 |
| descending aorta | 2 | 2 | 3 | 5 | 10 | |
| Patient 3 | ascending aorta | 1 | <1 | 4 | 2 | 1 |
| descending aorta | 2 | 4 | 3 | 6 | 3 | |
| Patient 4 | ascending aorta | 1 | 3 | 10 | 2 | 8 |
| descending aorta | 1 | 1 | 10 | <1 | 8 |
