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,

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.

Primary Outcome Measures
NameTimeMethod
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.

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
