Abstract

BACKGROUND: Outcomes of patients with hypertrophic cardiomyopathy (HCM) following transcatheter aortic valve replacement (TAVR) remain largely unknown.

OBJECTIVES: This study sought to assess the clinical characteristics and outcomes of HCM patients following TAVR.

METHODS: We queried the National Inpatient Sample from 2014 to 2018 for TAVR hospitalizations with and without HCM, creating a propensity-matched cohort to compare outcomes.

RESULTS: 207,880 patients that underwent TAVR during the study period, 810 (0.38%) had coexisting HCM. In the unmatched population, TAVR patients with HCM compared to those without HCM, were more likely to be female, had a higher prevalence of heart failure, obesity, cancer, and history of pacemaker/implantable cardioverter defibrillation, and were more likely to have nonelective and weekend admissions (p for all

CONCLUSION: Endovascular TAVR in HCM patients is associated with an increased incidence of in-hospital mortality and procedural complications.
