Treatment of late paravalvular regurgitation after transcatheter aortic valve implantation: prognostic implications

Eur Heart JPublished

  • Retrospective registry study
  • multicentre
  • 22 centres
  • consecutive patients
  • Median transcatheter aortic valve implantation (TAVI)-to-re-intervention time 207 (35; 765) days
  • Failed valve self-expanding in 129 (63.9%)

Authors' conclusion

This study describes the efficacy of transcatheter treatments for PVR after TAVI. Patients in whom PVR was successfully reduced had better prognosis.

Study context

Population
Patients undergoing transcatheter intervention for ≥ moderate paravalvular regurgitation (PVR) after index TAVI
Participants
