Valvular & structural heart diseaseCohort study
National Variability in Pacemaker Implantation Rate Following Transcatheter Aortic Valve Replacement (TAVR)
- Retrospective registry study
- multicentre
- hierarchical multivariable models
Authors' conclusion
Although PPM implantation rates have decreased over time, substantial site-level variation remains even after accounting for observed patient characteristics and site-level factors.
Study context
- Population
- TAVR procedures in the ACC/STS TVT Registry, 2016–2020TAVR procedures, 653 sites
- Participants
- 184,452 procedures
- Outcome
- Hospital-level variation and temporal trends in PPM implantation (in-hospital and 30-day) after TAVR
Main finding
As reported in the abstract
PPM implantation after TAVR · 2016–2020

- Site range of PPM rates
- 0%-36.4%
- Sites above 95th percentile CI (volume-adjusted)
- 34

- 28
- Site variation after patient-level adjustment, median OR
- 1.39 (95% CI 1.35-1.43, P < 0.001)
Observational data: associations, not effects.
