Left atrial strain prior to catheter ablation is consistently lower in patients who experience atrial fibrillation recurrence, although significant intervendor variability exists (p<0.0001).
Meta-Analysis
Does left atrial strain prior to catheter ablation predict atrial fibrillation recurrence?
Left atrial strain prior to catheter ablation predicts atrial fibrillation recurrence, though significant intervendor variability in strain measurements must be accounted for.
p-value: p=<0.0001
remained significant (p < 0.00001 and p < 0.0001 for TomTec and GE, respectively), while significant intervendor difference in absolute strain values was also detected (p < 0.0001 for both AFR and nAFR groups). LAS prior to catheter ablation is consistently lower in patients who experience AF recurrence. Its incorporation in clinical practice would assist physicians detect patients who require closer follow-up. Intervendor variability appears to be considerable and steps must be taken to document it thoroughly and mitigate it if possible.
Mouselimis et al. (Mon,) conducted a meta-analysis in Atrial fibrillation. Left atrial strain was evaluated on Atrial fibrillation recurrence (p=<0.0001). Left atrial strain prior to catheter ablation is consistently lower in patients who experience atrial fibrillation recurrence, although significant intervendor variability exists (p<0.0001).
