Comparison between the manual vs. MTT derived biplane volume and global function measures (n = 29)
| LA parameter | MTT | Manual | P | r | P |
|---|---|---|---|---|---|
| Vmax (ml) | 86.5 ± 33 | 84.4 ± 34 | 0.08 | 0.98 | <0.001 |
| LAEF (%) | 0.45 ± 0.13 | 0.44 ± 0.12 | 0.21 | 0.88 | <0.001 |
| LAPEF (%) | 0.17 ± 0.05 | 0.16 ± 0.08 | 0.67 | 0.57 | <0.001 |
| LAAEF (%) | 0.37 ± 0.1 | 0.36 ± 0.09 | 0.21 | 0.83 | <0.001 |
Results are reported as mean ± standard deviation
