Influence of severe anemia on procedural safety and one-year outcome after left atrial appendage closure: Insights from a very high-risk cohort.

ABSTRACT:

Introduction

Patients undergoing left atrial appendage closure (LAAC) are often severly anemic and close to the transfusion threshold. The aim was to investigate the prevalence of severe anemia in this cohort and if procedural safety is compromised compared with non-anemic patients.

Methods and results

Comparison of severly anemic patients (Hb < 80 g/l) vs. non-severly anemic patients in the prospective, multicentre observational LAARGE registry of patients undergoing LAAC. A total of 638 patients (anemia 22.3% vs non-anemic 77.7%) were included. Anemic patients were older (77.1 years ± 7.9 vs 75.6 years ± 7.9, p = 0.014), had more comorbidities, higher CHA2DS2-VASc (4.8 vs 4.4, p = 0.017) and higher HAS-BLED (4.3 vs 3.8, p < 0.001) scores. Implant success was not influenced
