Key result
Double left atrial appendage ligation was associated with significantly lower 30-day mortality compared to nonligated patients (0.7% vs 3.4%, P<0.0001).
Why the study?
Does double epicardial surgical ligation of the left atrial appendage reduce 30-day mortality and postoperative atrial fibrillation compared to no ligation?

Absolute Event Rate: 0.7% vs 3.4%
p-value: p=<0.0001
Double epicardial surgical ligation of the left atrial appendage is associated with significantly lower in-hospital and 30-day mortality compared to no ligation.
No takes yet. Share an insight, caveat, or question.
May support adjunctive double LAA ligation in surgery; leaves open randomized confirmation of benefit.
Zapolanski et al. (2013) conducted a cohort in Atrial fibrillation. Double left atrial appendage (LAA) ligation vs. Nonligated patients was evaluated on 30-day mortality (p=<0.0001). Double left atrial appendage ligation was associated with significantly lower 30-day mortality compared to nonligated patients (0.7% vs 3.4%, P<0.0001).
