Aortic Stenosis Treatment Evolution
- Aortic stenosis, the most common valve disease requiring intervention, is increasing in incidence.
- The biggest treatment advancement is TAVI, offering an alternative for previously untreatable cases.
Research Motivation
- The lack of diversity in research participants prompted questions about the true incidence of aortic stenosis.
- A national database for tracking this doesn't exist, leading to the current research.
Study Objectives and Methods
- The study aimed to explore the socio-demographic makeup of surgical AVR and TAVI patients over 20 years.
- It also investigated post-AVI outcome differences and COVID's impact across groups, using linked national datasets.
