Implication
May support LAA closure as warfarin alternative in non-valvular AF; leaves open need for randomized confirmation before practice change.
Structured PICO
Does transcatheter left atrial appendage closure prevent stroke in patients with non-valvular atrial fibrillation?
P
Population
Patients with non-valvular atrial fibrillation
I
Intervention
Transcatheter left atrial appendage (LAA) closure (e.g., Watchman device, Amplatzer Cardiac Plug)
C
Comparator
Anticoagulation with warfarin
O
Outcome
Combined endpoint (stroke prevention)composite
Transcatheter LAA closure is an emerging non-inferior alternative to warfarin for stroke prevention in non-valvular atrial fibrillation, though it requires experienced operators to minimize periprocedural complications.
Limitations
- Periprocedural complications such as pericardial effusion or stroke
