Comparison of left atrial volumes and emptying fraction from reference, standard, and focused-left-atrial cine images
| Short-axis cine images (Reference) | Standard Long axis cine images |
LA-focused Long axis cine images | p-value | |
|---|---|---|---|---|
| LAVmax (ml) | 82 (67–105) | 72 (55–93)* § | 83 (66–103) | 0.002 |
| LAVmin (ml) | 38 (30–55) | 29 (21–48)* § | 37 (27–53) | 0.001 |
| LAVmax-i (ml/m2) | 42 (36–54) | 38 (28–48)* § | 43 (37–55) | 0.001 |
| LAVmin-i (ml/m2) | 20 (16–30) | 16 (12–24)* § | 19 (15–28) | < 0.001 |
| LAEF (%) | 52 (45–58) | 56 (48–64)* | 55 (45–60) | 0.008 |
Data are expressed as median (interquartile range). Kruskal–Wallis one-way analysis of variance (Dunn’s post hoc test). *p < 0.05 vs. Reference; §p < 0.05 vs. LA-focused long axis
LAEF left atrial emptying fraction, LAVmax maximum left atrial volume, LAVmin minimum left atrial volume
