Key result
Concomitant LAAO during structural heart interventions achieves 100% procedural success with no long-term embolic events.
Why the study?
Trials of LAAO have excluded patients with valvar AF and structural heart diseases despite their increased thromboembolic risk.
Does concomitant left atrial appendage occlusion prevent embolic events in patients with atrial fibrillation undergoing structural heart interventions?
Observational (n=9)
No
Does concomitant left atrial appendage occlusion prevent embolic events in patients with atrial fibrillation undergoing structural heart interventions?
Concomitant left atrial appendage occlusion during structural heart interventions in patients with atrial fibrillation is feasible and may prevent cardioembolism without requiring lifelong oral anticoagulation.
No takes yet. Share an insight, caveat, or question.
May support concomitant LAAO to avoid anticoagulation in select AF cases; leaves open embolic benefit confirmation in larger trials.
Raghuram et al. (2020) conducted an observational in Atrial fibrillation with structural heart disease (n=9). Concomitant left atrial appendage occlusion (LAAO) was evaluated on Procedural success. Concomitant left atrial appendage occlusion during structural heart interventions was successfully performed in 100% of patients with no embolic events over a median follow-up of 2.8 years.
