Clinical Impact of Residual Leaks Following Left Atrial Appendage Occlusion: Insights From the NCDR LAAO Registry.

ABSTRACT:

Background

Data on the impact of residual peri-device leak after left atrial appendage occlusion (LAAO) are limited.

Objectives

The goal of this study was to explore the association of peri-device leak with adverse clinical events.

Methods

The National Cardiovascular Data Registry LAAO Registry was queried to identify patients undergoing LAAO between January 1, 2016, and December 31, 2019. Patients were classified according to leak size on echocardiography at 45 ± 14 days (0 mm, no leak; >0-5 mm, small leak; and >5 mm, large leak).

Results

A total of 51,333 patients were included, of whom 37,696 (73.4%) had no leak, 13,258 (25.8%) had small leaks, and 379 (0.7%) had large leaks. The proportion of patients on warfarin at 45 days was higher in the large vs small
