ABSTRACT

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is one of the primary treatment modalities for aortic stenosis (AS). Disparities affecting certain groups could result in lower utilization of this life-saving procedure. This study aims to investigate the effects of associated psychiatric conditions on the likelihood of TAVR in hospitalized AS patients.

METHODS: Our retrospective observational study used the National Inpatient Sample to identify hospitalized patients with AS. Using the International Classification of Diseases, 10th Revision, Clinical Modification patients were stratified into those without psychiatric comorbidities, and those with psychiatric comorbidities. The primary outcome was comparing the odds of TAVR between AS patients with and without psychiatric comorbidities. The secondary outcome assessed the association between TAVR and specific psychiatric comorbidities, using multivariable logistic regression while adjusting for prespecified covariates.

RESULTS: The study included 1,549,785 AS patients, of which 26% had psychiatric comorbidities. Patients with any psychiatric comorbidity had a significantly reduced likelihood of TAVR (adjusted odds ratio [aOR], 0.76; P < .001). For 2 psychiatric comorbidities, (aOR, 0.80; P < .001), and for more than 2 comorbid mental disorders (aOR, 0.46; P < .001). Lower TAVR odds were observed in patients with depression (aOR, 0.79), anxiety (aOR, 0.79), bipolar disorder (aOR, 0.74), substance use (aOR, 0.73), and psychotic disorders (aOR, 0.61), with P values < .001. There was no significant difference in the odds of surgical aortic valve replacement between those with and without psychiatric comorbidities.

CONCLUSIONS: AS patients with psychiatric conditions face reduced TAVR likelihood. Further research is needed to confirm, explore, and address factors contributing to this disparity.
