AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults whose surgical bioprosthetic aortic valve has failed and who are approved for a valve-in-valve procedure with the SAPIEN 3 Ultra valve.

Age
18 years and older
Sex
All
Disease stage
Failed surgical bioprosthetic aortic valve, with severe aortic stenosis and/or regurgitation, approved by the Heart Team for a valve-in-valve procedure.
Earlier treatment
A surgical stented bioprosthetic aortic valve (label size ≤25 mm) already in place.

Main reasons for not taking part

  • Stentless or sutureless surgical valves
  • Trifecta bioprosthesis
  • Hancock II bioprosthesis
  • High risk of coronary obstruction (valve-to-coronary distance on CT <4 mm, or Heart Team judgement)
  • Cannot give written informed consent

Original description
Data on valve performance following ViV-TAVR has usually been obtained with the use of Doppler-echocardiography. However, some reports have shown significant discordances in the evaluation of mean transvalvular gradient between echocardiography and catheterization, with an overestimation of the real gradient with echo (vs. cath) in most cases.

Valve Hemodynamic Optimization Based on Doppler-Echocardiography Versus Catheterization Measurements Following Valve-in-Valve TAVR: A Prospective Randomized Trial

Data on valve performance following ViV-TAVR has usually been obtained with the use of Doppler-echocardiography. However, some reports have shown significant discordances in the evaluation of mean transvalvular gradient between echocardiography and catheterization, with an overestimation of the real gradient with echo (vs. cath) in most cases.

Inclusion: Patients with surgical aortic bioprosthetic valve failure defined as severe aortic stenosis and/or regurgitation approved for a valve-in-valve procedure by the Heart Team; Surgical stented bioprosthetic valve (label size ≤25 mm); TAVR with the SAPIEN 3 Ultra valve.

Exclusion: Stentless or sutureless surgical valves; High-risk of coronary obstruction (defined either as a virtual transcatheter valve - coronary distance as evaluated by CT <4 mm or based on the criterion of the heart team responsible for the procedure); Trifecta bioprosthesis; Hancock II bioprosthesis; Impossibility to obtain written informed consent.
