Non-white patients are underrepresented in left atrial appendage occlusion (LAAO) trials, and racial disparities in LAAO periprocedural management are unknown.
We assessed sociodemographics and comorbidities of consecutive patients at our institution undergoing LAAO between 2015 – 2020, then in adjusted analyses, compared procedural wait time, procedural complications, and post-procedure oral anticoagulation (OAC) use in whites versus non-whites.
Among 109 patients undergoing LAAO (45% white), whites had lower CHA2DS VASc scores, on average, than non-whites (4.0 vs. 4.8, p = 0.006). There was no difference in median time from index event or initial outpatient cardiology encounter to LAAO procedure (whites 10.5 vs. non-whites 13.7 months, p = 0.9; 1.9 vs 1.8 months, p = 0.6, respectively), and there was no difference in procedural complications (whites 4% vs. non-whites 5%, p = 0.33). After adjusting for CHA2DS2VASc score, OAC use at discharge tended to be higher in whites (OR 2.4, 95% CI [0.9-6.0], p = 0.07). When restricting the analysis to those with prior gastrointestinal (GI) bleed, adjusting for CHA2DS2VASc score and GI bleed severity, whites had a nearly five-fold odds of being discharged on OAC (OR 4.6, 95% CI [1-21.8], p = 0.05). The association between race and discharge OAC was not mediated through income category (total mediation effect 19% 95% CI [-.04-0.11], p = 0.38).
Despite an increased prevalence of comorbidities amongst non-whites, wait time for LAAO and procedural complications were similar in whites versus non-whites. Among those with prior GI bleed, whites were nearly five-fold more likely to be discharged on OAC than non-whites, independent of income. This article is protected by copyright. All rights reserved.
