Differences in the presentation and management of patients with severe aortic stenosis in different European centres
Key result
Patients with severe aortic stenosis in Germany had more advanced disease and significantly higher rates of planned aortic valve replacement within 3 months (87.3%) compared to France (71.6%) and the UK (50.2%).
Why the study?
Differences in the management and treatment of severe aortic stenosis between Germany, France, and the UK were investigated to allow healthcare system benchmarking and identify levers for improvement.

Implication
Regional disparities may delay care in the UK; leaves open effects on outcomes and need for harmonized pathways.

Main Result
Absolute Event Rate: 87.3% vs 50.2%
p-value: p=<0.001
Significant regional disparities exist in the management of severe aortic stenosis across Europe, with Germany demonstrating higher intervention rates and shorter waiting times compared to the UK.
Limitations
- Data collected from a limited number of centers, which may not be fully representative of the European situation or all centers in participating countries.
- Reasons for not performing an AVR may not have been fully recorded.
- Analysis period was limited to 3 months, not capturing interventions performed later.
- Study was not powered to determine the optimal timing of AVR or the impact of treatment delay on mortality.

Lutz et al. (2020) conducted an observational in Severe aortic stenosis (n=2,052). Healthcare system (Germany vs France vs UK) vs. Between countries was evaluated on Aortic valve replacement (AVR) planned within 3 months (p=<0.001). Patients with severe aortic stenosis in Germany had more advanced disease and significantly higher rates of planned aortic valve replacement within 3 months (87.3%) compared to France (71.6%) and the UK (50.2%).
