Periprocedural Pericardial Effusion Complicating Transcatheter Left Atrial Appendage Occlusion: A Report From the NCDR LAAO Registry.

ABSTRACT:

Background

Pericardial effusion (PE) is a potential complication of transcatheter left atrial appendage occlusion. The objective of this study was to investigate the incidence, associated characteristics, and outcomes of PE following left atrial appendage occlusion.

Methods

Patients in the NCDR LAAO Registry who underwent a Watchman procedure between January 1, 2016 and December 31, 2019 were included. The primary outcome was in-hospital PE requiring intervention (percutaneous drainage or surgery). Odds ratios (ORs) were calculated for adverse event rates associated with PE.

Results

The study population consisted of 65 355 patients. The mean patient age was 76.2±8.1 years, and the mean CHA₂DS₂-VASc score was 4.6±1.5. PE occurred in 881 patients (
