Key result
Each 1 mL/m2 increase in the left atrial volume index was associated with a 15% increased risk of atrial fibrillation recurrence 3 months after electrical cardioversion (OR 1.154).
Why the study?
Does baseline left atrial volume index (LAVI) predict the recurrence of atrial fibrillation at 3 months after electrical cardioversion in patients with non-valvular persistent AF?
Cohort (n=51)

Odds Ratio: 1.154 (95% CI 1.053–1.264)
p-value: p=<0.001
Baseline left atrial volume index (LAVI) is a strong, independent predictor of atrial fibrillation recurrence 3 months after electrical cardioversion, with values >55 mL/m2 indicating a high risk of relapse.
No takes yet. Share an insight, caveat, or question.
LAVI may stratify post-cardioversion AF recurrence risk; hypothesis-generating and should not yet change practice.
Toufan et al. (2017) conducted a cohort in Non-valvular persistent atrial fibrillation (n=51). Left atrial volume index (LAVI) was evaluated on Atrial fibrillation recurrence (OR 1.154, 95% CI 1.053-1.264, p=<0.001). Each 1 mL/m2 increase in the left atrial volume index was associated with a 15% increased risk of atrial fibrillation recurrence 3 months after electrical cardioversion (OR 1.154).
