Regional assessment of availability for transcatheter aortic valve implantation in Sweden: a long-term observational study
Authors' conclusion
This nationwide study indicated no regional differences in terms of availability, short-term mortality, or waiting times.
Study context
- Population
- All patients undergoing transcatheter aortic valve implantation (TAVI) in Sweden 2008–2020 (SWENTRY registry)
- Participants
- 7,280 patients
- Exposure
- Regions with vs without a local TAVI centre
- Outcome
- Regional differences in TAVI availability (incidence), short-term mortality and waiting times
Methodological detailsnationwide, long-term, SWENTRY linked to National Cause of Death Registry and Statistics Sweden geospatial data

Main finding
As reported in the abstract
Regional differences in availability, 30-day mortality and waiting time
- No significant regional difference in incidence between counties with vs without a local TAVI centre
- P = 0.7
- No clustering around regions with a local TAVI centre
- P = 0.99
- No regional difference in waiting time from decision to intervention
- P = 0.7
Observational data: associations, not effects.
Further findings
Temporal trends in TAVI and surgical aortic valve replacement (SAVR)
- TAVI interventions increased markedly; SAVR remained constant
