Atrial functional parameters in study groups.
| Variables | Control group (n= 20) | MVP group (n= 20) | P value |
|---|---|---|---|
| LAV max indexed (ml/m2) | 32.5 (27.25–33.75) | 44.5 (30.25–76) | 0.127 |
| LAV min indexed (ml/m2) | 12.5 (11–14) | 22.5 (15.25–41) | < 0.001* |
| Total LA EF (%) | 60 (53–64.9.9) | 49.6 (42.2–65) | 0.174 |
| Passive LA EF (%) | 32.4 (22.5–48.3) | 31.6 (22.7–35.6) | 0.758 |
| Active LA EF (%) | 42 (31–45) | 28.6 (16.9–48.3) | 0.602 |
| LACI (%) | 42.3 9(25–55.4.4) | 41 (32–51) | 0.752 |
NB: Quantitative data are expressed as median (IQR) (Mann-Whitney U-test)*: Statistically significant. LAV max: left atrial volume maximum, LAV min: left atrial volume minimum LA: left atrium, EF: ejection fraction, PAC: pre-atrial contraction, LACI: left atrioventricular coupling index.
