Valvular & structural heart diseaseCohort study
Surgical Bailout During Transcatheter Aortic Valve Replacement (TAVR)
- Retrospective cohort study
- national Medicare data
- multilevel hierarchal model
Authors' conclusion
In contemporary data, the annual incidence of TAVR surgical bailout is decreasing, but the short-term mortality remains high. However, patients who survived 1 year after TAVR had similar long-term mortality to patients without surgical bailout.
Study context
- Population
- Medicare beneficiaries who underwent TAVR, 2016–2024
- Participants
- 400,862 TAVRs
- Exposure
- TAVR with surgical bailout vs TAVR without bailout
- TAVR bailoutn = 2,240
- Outcome
- 30-day mortality
- Follow-up
- 30 days
Main finding
As reported in the abstract
30-day mortality of TAVR bailout
TAVR bailout
26.3%
588 of 2,240
Observational data: associations, not effects.
Further findings
- Incidence of TAVR bailout
- 0.56% · 2,240 of 2,240
- Incidence of TAVR bailout — Annual incidence decreased 2016 to 2024
- P < 0.001
- 30-day mortality of TAVR bailout by hospital surgical aortic valve replacement (SAVR) volume — 30-day mortality similar across volume categories
- P = 0.28
- 30-day mortality of TAVR bailout by hospital SAVR volume: Low-volume SAVR hospitals 27%
- 30-day mortality of TAVR bailout by hospital SAVR volume: Intermediate-volume SAVR hospitals 29%
- 30-day mortality of TAVR bailout by hospital SAVR volume: High-volume SAVR hospitals 25%
Mortality, landmark analysis
- Higher mortality with TAVR bailout vs without bailout up to 1 year
- P < 0.001
- Similar mortality after 1 year
- P = 0.53
- median follow-up 952 days (IQR: 414-1,615 days)
