Key result
Cardiac CT in patients with persistent AF revealed significant regional variability in left atrial wall thickness (average 1.89 ± 0.48 mm), with the roof and mitral isthmus thicker than the posterior wall (P<0.001).
Cross-Sectional (n=60)
In patients with persistent AF, there is significant regional variability in left atrial wall thickness, which may impact the safety and efficacy of transmural lesion creation during catheter ablation.

LA wall thickness heterogeneity may impact transmural lesion formation during AF ablation; leaves open optimal energy titration by region.
Beinart et al. (2011) conducted a cross-sectional in Persistent atrial fibrillation (n=60). 64 slice cardiac computed tomography (CT) was evaluated on Regional left atrial wall thickness. Cardiac CT in patients with persistent AF revealed significant regional variability in left atrial wall thickness (average 1.89 ± 0.48 mm), with the roof and mitral isthmus thicker than the posterior wall (P<0.001).
