Longitudinal and circumferential ventricular and atrial strains measured at basal and mid cavity slice level and arranged according to the median (32 %) of atrial % conduit contribution to ventricular stroke volume
| Conduit contribution to ventricular stroke volume | ≤32 % | >32 % | 2-ANOVA with repeated measurements |
|---|---|---|---|
| Basal ventricular longitudinal strain | −0.09 ± 0.03 | −0.08 ± 0.03 | Interaction effect, p = 0.62 |
| Mid ventricular longitudinal strain | −0.11 ± 0.03 | −0.10 ± 0.04 | Slice level effect, p = 0.003 |
| Basal ventricular circumferential strain | −0.10 ± 0.04 | −0.11 ± 0.05* | Interaction effect, p = 0.021 |
| Mid ventricular circumferential strain | −0.10 ± 0.05 | −0.08 ± 0.04 | Slice level effect, p = 0.002 |
| Basal atrial longitudinal strain | 0.12 ± 0.11 | 0.06 ± 0.07 | Slice level effect, p = 0.87 |
| Mid atrial longitudinal strain | 0.12 ± 0.09 | 0.07 ± 0.09 | Conduit effect, p = 0.044 |
| Basal atrial circumferential strain | 0.15 ± 0.14 | 0.08 ± 0.11 | Slice level effect, p = 0.002 |
| Mid atrial circumferential strain | 0.09 ± 0.09 | 0.06 ± 0.07 | Conduit effect, p = 0.09 |
