About this study

Official title: REVIVE-FR: A French Multicenter, Prospective and Retrospective, Observational Registry of TAVI-in-SAVR (Valve-in-Valve), THV-in-THV (Redo-TAVI), Surgical Explantation, and Medical Management for Failed Aortic Bioprostheses

This registry aims to investigate treatment options for patients whose previously implanted biological aortic heart valve no longer functions properly. As patients with severe aortic stenosis are increasingly younger and at lower surgical risk, more patients may experience bioprosthetic valve failure during their lifetime.

Treatment options include implanting a new valve inside the existing valve using a catheter-based procedure, surgically removing the failed valve, or providing conservative medical treatment. The study will evaluate outcomes associated with these different treatment strategies to improve understanding of their benefits and risks and help guide future treatment decisions for patients with bioprosthetic valve failure.

Read the detailed description

Bioprosthetic valve failure (BVF) is an increasingly relevant clinical problem as younger patients with severe aortic stenosis undergo surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) and may outlive the expected durability of their implanted valve. BVF can result from structural valve deterioration, non-structural valve dysfunction, valve thrombosis, or endocarditis. Depending on the underlying mechanism, anatomical characteristics, surgical risk, and clinical circumstances, treatment options include transcatheter valve-in-valve implantation into a failed surgical bioprosthesis (TAVI-in-SAVR), repeat transcatheter aortic valve implantation within a failed transcatheter heart valve (THV-in-THV or redo-TAVI), surgical explantation of the failed transcatheter heart valve, or medical management without reintervention.

Evidence regarding the comparative outcomes of these management strategies remains limited, particularly for patients undergoing surgical explantation and those managed conservatively. Repeat transcatheter procedures may be associated with complications such as coronary obstruction, impaired coronary access, and elevated residual transvalvular gradients. Preprocedural computed tomography (CT) may help identify anatomical characteristics associated with these risks, including the virtual transcatheter heart valve-to-coronary distance (VTC), the virtual transcatheter heart valve-to-sinotubular junction distance (VTSTJ), and the height of the neoskirt formed by the displaced leaflets of the failed prosthesis.

REVIVE-FR is a multicenter French registry designed to collect real-world clinical data on patients with bioprosthetic valve failure managed using different treatment strategies. The registry will include patients undergoing TAVI-in-SAVR, redo-TAVI (THV-in-THV), surgical explantation of a failed transcatheter heart valve, or medical management without reintervention.

Baseline characteristics, procedural data where applicable, and follow-up information will be collected. Assessments will include clinical outcomes, echocardiographic findings, and CT-based anatomical measurements. The registry will evaluate procedural success using a VARC-3-adapted composite endpoint and safety outcomes according to VARC-3 definitions at 30 days. Clinical, echocardiographic, and CT-based outcomes will also be assessed at 1 year and, where data are available, at 2 years.

The registry aims to characterize outcomes across the different management strategies and identify patient-related, anatomical, and valve-related factors associated with complications and clinical benefit. Particular attention will be given to the mechanisms of bioprosthetic valve failure and CT-derived predictors of coronary obstruction and other complications associated with repeat transcatheter valve implantation. Patients receiving medical management without reintervention will provide a real-world reference cohort to improve understanding of the clinical course of BVF in the absence of further valve intervention.

In addition, data from the redo-TAVI cohort are intended to be combined with data from another registry to support a larger, adequately powered analysis of outcomes following THV-in-THV procedures. Overall, REVIVE-FR is intended to expand the available evidence on the management of bioprosthetic valve failure and support a better understanding of the benefits, risks, and clinical outcomes associated with the available treatment strategies. The study combines prospective enrollment with a partial, exceptional retrospective identification of eligible cases from January 2025 onward.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. REVIVE-FR Success at 30 Days

    Proportion of patients in the TAVI-in-SAVR, THV-in-THV, and Explant-TAVR cohorts achieving REVIVE-FR success, a VARC-3-adapted composite endpoint. Success requires correct positioning of a single prosthetic heart valve in the proper anatomic location; intended valve performance (mean gradient <20 mmHg, peak velocity <3.0 m/s, Doppler velocity index ≥0.25, and less than moderate aortic regurgitation); and freedom from mortality, coronary obstruction, unplanned coronary revascularization, and surgery or intervention related to the device. The endpoint is assessed separately for each of the three interventional cohorts and does not apply to the Medical-Management cohort.

    Measured: 30 days after procedure

  2. Early Safety at 30 Days

    Determine VARC-3 defined early safety at 30 days:

    • Freedom from all-cause mortality
    • Freedom from all Stroke
    • Freedom from all VARC type 2-4 bleeding
    • Freedom from all major vascular, access-related, or cardiac structural complication
    • Freedom from all acute kidney injury stage III/IV
    • Freedom from all moderate/severe aortic regurgitation
    • Freedom from all new permanent pacemaker implantations due to procedure-related conduction abnormalities
    • Freedom from all surgery/intervention related to the device

    These events will be adjudicated. Number and percentage of subjects with early safety at 30 days as per VARC-3 definition, along with individual component of the success, will be presented.

    Measured: 30 days after procedure

Secondary outcomes (6)
  1. Clinical Outcomes at 1 Year

    Composite of freedom from all-cause mortality, stroke, and valve- or procedure-related rehospitalization in the TAVI-in-SAVR, THV-in-THV, and Explant-TAVR cohorts.

    Measured: 1 year after procedure

  2. Valve Durability at 1 Year

    Incidence of subclinical and clinical transcatheter heart valve thrombosis and Stage II/III structural valve degeneration according to VARC-3, assessed by echocardiography and 1-year CT where available.

    Measured: 1 year after procedure

  3. All-Cause and Cardiovascular Mortality in the Medical-Management Cohort

    All-cause and cardiovascular mortality will be assessed descriptively in patients managed medically for a failing transcatheter heart valve. Results will be reported as the number and percentage of patients, where appropriate. This outcome is intended for descriptive characterization and is not powered for direct comparison with the interventional cohorts.

    Measured: 1 year, and optional 2 years after procedure

  4. Heart Failure Hospitalization in the Medical-Management Cohort

    Occurrence of hospitalization for heart failure during follow-up will be assessed descriptively in the Medical-Management cohort. Results will be reported descriptively and are not intended for direct statistical comparison with the interventional cohorts

    Measured: 1 year; and optional 2-year after procedure

  5. Unplanned Aortic Valve Reintervention in the Medical-Management Cohort

    Occurrence of unplanned aortic valve reintervention, including crossover to TAVI-in-SAVR, THV-in-THV, or surgical explantation, will be assessed descriptively in patients initially managed medically.

    Measured: 1 year; and optional 2-year after procedure

  6. Echocardiographic Progression of Transcatheter Heart Valve Failure

    Progression of transcatheter heart valve failure will be assessed descriptively using echocardiographic findings, including changes in VARC-3 structural valve degeneration stage and, in patients with endocarditis, resolution or persistence of endocarditis.

    Measured: 1 year; and optional 2-year after procedure
