Study Details

Study Description

Brief Summary

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. Thus, the incidence of procedural-device failure may be lower than that reported in the ViV-TAVR literature,

Condition or Disease Intervention/Treatment Phase
  • Procedure: Doppler-echocardiography
  • Procedure: Invasive hemodynamic measurements
N/A

Detailed Description

This is a prospective, multicenter, randomized, single-blinded design trial including patients with surgical aortic bioprosthetic dysfunction in the presence of a stented surgical bioprosthesis with a labeled size ≤25 mm. Following the Heart Team's decision to proceed with a ViV-TAVR procedure with the SAPIEN 3 ULTRA valve (or its subsequent iterations), patients will be randomized to valve hemodynamic optimization according to Doppler-echocardiography versus cardiac catheterization parameters.

Arms and Interventions

Arm Intervention/Treatment
Other: Doppler-echocardiography

Following valve implantation, further intervention will be based on Doppler-echocardiographic measurements.

Procedure: Doppler-echocardiography
The TAVR (valve-in-valve) procedure will be performed with the SAPIEN 3 Ultra valve, with valve sizing according to current manufacturer recommendations. Following valve implantation, further intervention will be based on Doppler-echocardiographic measurements. Balloon post-dilation with a non-compliant balloon will be performed in the presence of a residual mean gradient ≥20 mmHg as assessed by Doppler-echocardiography.

Other: Invasive hemodynamic measurements

Following valve implantation, further interventions will be based on invasive hemodynamic measurements (with simultaneous aortic and ventricular pressure recording).

Outcome Measures

Primary Outcome Measures

  1. Changes in Quality of life (Efficacy) [12 months follow-up]

    Change in quality of life as evaluated by the Kansas City Cardiomyopathy Questionnaire (KCCQ). All score are represented on a 0-to-100-point scale (lower scores represent more severe symptoms and/or limitations and scores of 100 indicate no symptoms, no limitations, and excellent quality of life).The KCCQ is a 7 domains questionnaire; symptom frequency, symptom burden, symptom stability, physical limitations, social limitations, quality of life and self-efficacy.

  2. Periprocedural complications (Safety) [Periprocedural]

    Periprocedural complications including in-hospital mortality, stroke, annular rupture, coronary obstruction, new-onset left bundle branch block, need for permanent pacemaker implantation and conversion to open heart surgery.

Secondary Outcome Measures

  1. Residual transvalvular gradient [1 month and 12 months follow-up]

    Residual (maximal and mean) transvalvular gradient

  2. Combined enpoint: Moderate or severe prothesis-patient mismatch and/or moderate or severe aortic regurgitation (valve performance) [1 month and 12 months follow-up]

    Moderate or severe prothesis-patient mismatch (defines as an index aortic valve area 0.85-0.66 cm2/m2 (moderate), ≤0.65 cm2/m2 (severe) for patient with BMI ˂30km/m2 and 0.70-0.56 cm2/m2 (moderate), ≤0.55 cm2/m2 (severe) for patient with BMI ≥30km/m2 and/or moderate-severe aortic regurgitation (AR) (VARC-3 definition).

  3. Heart failure [1 and 12 months follow-up and yearly up to 5 years]

    Evaluated by the New York Heart Association (NYHA) Functional Classification

  4. Exercise capacity [1 month and 12 months follow-up]

    Exercise capacity as evaluated by the six-minute wlak test.

  5. Changes in Quality of life [after 1-year follow-up (yearly up to 5 years)]

    severe symptoms and/or limitations and scores of 100 indicate no symptoms, no limitations, and excellent quality of life).The KCCQ is a 7 domains questionnaire; symptom frequency, symptom burden, symptom stability, physical limitations, social limitations, quality of life and self-efficacy.

  6. Clinical safety endpoints [1 and 12 months follow-up and yearly up to 5 years]

    Individually and combined: death, stroke, major of lifethreatening bleeding, pacemaker implantation, myocardial infarction

  7. re-hospitalization [1 and 12 months follow-up and yearly up to 5 years]

    Need for re-hospitalization

  8. wear and tear deterioration (Structural valve degeneration) [1 and 12 months follow-up and yearly up to 5 years]
