Key result
Left atrial appendage closure offers an alternative to long-term anticoagulation for atrial fibrillation, providing decreased bleeding risk but potentially less protection against ischemic events.
Why the study?
Concerns remain regarding up-front risks of device implantation and efficacy in preventing embolic events compared with oral anticoagulation in atrial fibrillation.
Does left atrial appendage closure prevent embolic complications compared to oral anticoagulation in patients with atrial fibrillation?
Does left atrial appendage closure prevent embolic complications compared to oral anticoagulation in patients with atrial fibrillation?
LAAC devices serve as a potential alternative to long-term anticoagulation with decreased bleeding risk but less protection against ischemic events, requiring individualized risk-benefit analysis.
May support individualized AF decisions balancing bleeding versus ischemic risks; leaves open need for randomized LAAC comparisons.
To date, left atrial appendage closure (LAAC) devices continue to be assessed as an intuitive alternative to oral anticoagulant therapy to prevent embolic complications in patients with atrial fibrillation. Concerns remain about the up-front risks associated with device implantation as well as device efficacy in preventing embolic events as compared with anticoagulation. Currently, LAAC devices serve as a potential alternative to long-term anticoagulation with the benefit of decreased bleeding risk but with less protection against ischemic events. An individualized risk-benefit analysis with regard to stroke possibility, bleeding likelihood with long-term anticoagulation, the risks of an invasive procedure, and the risks associated with having a lifelong intracardiac device should be performed to guide careful patient selection for this operation.

Infeld et al. (2019) conducted a review in Atrial Fibrillation. Left atrial appendage closure vs. Oral anticoagulation was evaluated. Left atrial appendage closure offers an alternative to long-term anticoagulation for atrial fibrillation, providing decreased bleeding risk but potentially less protection against ischemic events.
