Key result
Increased left atrial wall thickness was significantly associated with post-ablation atrial fibrillation recurrence (1.6 ± 0.6 mm vs. 1.5 ± 0.5 mm, P < 0.001) and electrical reconnection.
Why the study?
Does increased left atrial wall thickness predict atrial fibrillation recurrence and electrical reconnection after radiofrequency ablation?
Cohort (n=86)

Absolute Event Rate: 1.6% vs 1.5%
p-value: p=<0.001
Increased left atrial wall thickness is associated with a higher risk of atrial fibrillation recurrence and electrical reconnection following radiofrequency ablation.

LA thickness associated with post-ablation reconnection; hypothesis-generating for thickness-guided strategies in AF.
Inoue et al. (2016) conducted a cohort in Atrial fibrillation (n=86). Increased left atrial wall thickness vs. Normal/thinner left atrial wall thickness was evaluated on Left atrial wall thickness in patients with recurrent atrial fibrillation versus successfully treated patients (p=<0.001). Increased left atrial wall thickness was significantly associated with post-ablation atrial fibrillation recurrence (1.6 ± 0.6 mm vs. 1.5 ± 0.5 mm, P < 0.001) and electrical reconnection.
