Ahmed et al. (2026) conducted an observational in Atrial fibrillation (n=411). Left atrial appendage occlusion (LAAO) was evaluated on Failure to deploy the LAAO device (unsuccessful device implantation). Left atrial appendage occlusion demonstrated a low failure rate, with unsuccessful device implantation occurring in 4.9% of procedures.
