Key result
Minimalist LAAO using only periprocedural imaging achieves ~99% procedural success and low long-term stroke rates.
Why the study?
Pre- and post-procedural imaging in LAAO adds to patient inconvenience and risks without clearly influencing outcomes, suggesting a minimalist approach with only periprocedural imaging may suffice.
Does a minimalist left atrial appendage occlusion approach guided only by periprocedural imaging maintain procedural success and prevent long-term cerebrovascular events in patients requiring LAAO?

May support peri-procedural imaging alone for LAAO; hypothesis-generating and should not yet change practice.

Does a minimalist left atrial appendage occlusion approach guided only by periprocedural imaging maintain procedural success and prevent long-term cerebrovascular events in patients requiring LAAO?
A minimalist LAAO approach using only periprocedural imaging is feasible and safe, achieving high procedural success and significant long-term reductions in cerebrovascular events.
Wong et al. (2026) conducted an observational in Atrial fibrillation requiring left atrial appendage occlusion (n=247). Minimalist left atrial appendage occlusion guided only by periprocedural imaging vs. Expected event rates based on CHA2DS2-VASc and HAS-BLED scores was evaluated on Clinical stroke. Minimalist left atrial appendage occlusion using only periprocedural imaging achieved a 99.2% procedural success rate and a 6.9% rate of clinical stroke over a median 6.8 years of follow-up.
