Valvular & structural heart diseaseCohort study
Hospital Volume and Failure to Rescue Post-TAVR
- Retrospective cohort study
- registry-based
- multicentre
Authors' conclusion
In this large contemporary study, we found that higher annualized TAVR volume was associated with lower complication rates but not with lower FTR rates.
Study context
- Population
- Patients undergoing transcatheter aortic valve replacement (TAVR) in the STS/ACC TVT Registry, 2017–2023
- Participants
- 487,159 patients · 808 sites
- Exposure
- TAVR hospital volume quartiles
- Outcome
- FTR (risk-adjusted mortality after a major complication post TAVR)
- Follow-up
- 30 days
Main finding
FTR
Adjusted odds ratio
0.97 per 100 cases
95% CI 0.93–1.01
P = 0.11
Hospital volume
adjusted OR 0.97 per 100 cases (95% CI 0.93–1.01); P = 0.11
Per 100 cases, as printed
As reported in the abstract
- Overall failure to rescue (FTR) rate across all hospitals
- 11.0%
Observational data: associations, not effects.
