AIM: To investigate trends in the utilization of transcatheter aortic valve replacement (TAVR) and changes in the characteristics of patients undergoing first-time TAVR.

METHODS: Using Danish nationwide registers, we included all patients undergoing TAVR between 2008 and 2020. To compare patient characteristics, the study population was stratified according to calendar year of procedure: 2008-2010, 2011-2013, 2014-2016, and 2017-2020.

RESULTS: We identified 6,097 patients undergoing TAVR with year-by-year increases in TAVR penetration rate. Over time, the age of the patients remained stable (2008-2010: median age 82 year [interquartile range (IQR): 77-86] vs 2017-2020: median age 81 years [IQR: 77-85]). Moreover, there was an increase in male patients (2008-2010: 49.9% vs 2017-2020: 57.4%) and patients with diabetes (2008-2010: 14.2% vs 2017-2020: 19.2%). Conversely, a history of stroke (2008-2010: 15.8% vs 2017-2020: 13.1%), previous myocardial infarction (2008-2010: 22.4% vs 2017-2020: 10.0%), heart failure (2008-2010: 40.5% vs 2017-2020: 25.2%), and peripheral artery disease (2008-2010: 14.8% vs 2017-2020: 10.4) decreased among patients.

CONCLUSIONS: TAVR utilization increased markedly in the years 2008-2020. Patients undergoing TAVR had less comorbidity over time while age remained stable. Thus, despite expanding to patients at lower surgical risk, TAVR is still offered mainly to older patients.
