Key result
LAA resection during surgical AF ablation is linked to reduced overall mortality vs. preservation.
Why the study?
The clinical impact of left atrial appendage resection during surgical ablation of atrial fibrillation on postoperative stroke and sinus rhythm maintenance was evaluated due to its proposed benefits.
Does left atrial appendage resection reduce TIA/stroke and mortality in patients undergoing surgical ablation of atrial fibrillation during cardiac surgery?
Cohort (n=599)
No
Does left atrial appendage resection reduce TIA/stroke and mortality in patients undergoing surgical ablation of atrial fibrillation during cardiac surgery?
p-value: p=0.0008
Left atrial appendage resection during surgical ablation of atrial fibrillation is associated with significantly lower mortality and a trend toward fewer strokes/TIAs at 1 year.
LAA resection during surgical AF ablation was associated with lower mortality; leaves open whether it reduces stroke in randomized trials.

Kurfirst et al. (2015) conducted a cohort in Atrial fibrillation (n=599). Left atrial appendage resection vs. Left atrial appendage preservation was evaluated on Overall mortality (p=0.0008). Left atrial appendage resection during surgical ablation of atrial fibrillation was associated with a statistically significant decrease in overall mortality compared to appendage preservation (p=0.0008).
