  • Retrospective registry study
  • multicentre

Authors' conclusion

The JVT platform has a better acute performance than other THVs when used off-label for inoperable patients with severe AR.

Study context

Population
Inoperable patients with severe pure native-valve aortic regurgitation (AR) (bicuspid valve excluded)
Participants
256 patients
Exposure
Purpose-built Jena Valve Trilogy (JVT) vs off-label transcatheter heart valves (THVs)
  • JVTn = 88
  • Off-label THVsn = 168reference
Outcome
Technical and device success, 1-year all-cause mortality, and composite of 1-year mortality and HF rehospitalization

Main finding

As reported in the abstract

Technical and device success; 1-year all-cause mortality; 1-year composite of mortality and HF rehospitalization

Technical success

P < 0.001

Device success

P < 0.001

No significant difference in 1-year mortality, HR 0.99
P = 0.980
No significant difference in 1-year composite endpoint, HR 1.5
P = 0.355

Observational data: associations, not effects.

Further findings

THV embolization, need for second valve, moderate residual AR

THV embolization

Second valve

Moderate residual AR

  • THV embolization, need for second valve, moderate residual AR: embolization P < 0.001
  • THV embolization, need for second valve, moderate residual AR: second valve P = 0.004
  • THV embolization, need for second valve, moderate residual AR: residual AR P = 0.007

Safety

Permanent pacemaker implantation · comparable

P = 0.70
