What is being measured

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

    Absence of implant or delivery related serious adverse events at 30 days

    Measured: 30 days

Secondary outcomes (11)

    All of the following must be present:

    1. Deployment of the device

    II. Absence of major device- or procedure-related SAEs, including:

    1. Death
    2. Stroke
    3. Life-threatening bleeding (Mitral Valve Academic Research Consortium [MVARC] definition)

    4. Continued intended safety and performance of the device, including:
    5. No evidence of major structural or functional failure
    6. No specific, major device-related technical failure issues and complications
    7. Reduction of MR to either optimal or acceptable levels* without significant mitral stenosis (i.e., post-procedure effective orifice area [EROA] ≥ 1.5 cm2 with transmitral mean gradient < 5 mmHg), no greater than mild (1+) paravalvular leak (PVL), and no hemolysis

    Measured: 30 days, 3, 6, 12 months and annually up to 5 years

  4. Patient Success

    All of the following must be present:

    1. Deployment of the device
    2. Patient returned to the pre-procedural setting; and
    3. No rehospitalizations or reinterventions for the underlying condition (e.g., MR, heart failure); and
    4. Improvement from baseline in symptoms (e.g., New York Heart Association [NYHA] Class improvement by ≥ 1 class); and
    5. Improvement from baseline in functional status (e.g., 6-minute walk test/distance [6MWT/D] improvement by ≥ 50 m); and
    6. Improvement from baseline in quality-of-life (e.g., Kansas City Cardiomyopathy Questionnaire [KCCQ-12] improvement by ≥ 10 points)

    Measured: 1 year

  5. Change in NYHA Class

    New York Heart Association (NYHA) functional classification of heart failure is based on how much a patient is limited during physical activity. The rating ranges from Class I-IV. Class I = no limitations of physical activity; Class II = slight limitations of physical activity, ordinary physical activity results in fatigue, palpitation, shortness of breath; Class III = marked limitations of physical activity, less than ordinary activity causes fatigue, palpitation, or shortness of breath; Class IV = unable to carry on any physical activity without discomfort, symptoms of heart failure at rest.

    Measured: 30 days, 3, 6, 12 months and annually up to 5 years

  6. Increase in 6MWD

    Measured: from baseline to 30 days, 3, 6, 12 months and annually up to 5 years

  7. Quality of life change (KCCQ-12)

    The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. An overall summary score can be derived from the physical function, symptom (frequency and severity), social function, and quality of life domains. Scores are transformed to a range of 0-100, in which higher scores reflect better health status.

    Measured: from baseline to 30 days, 3, 6, 12 months and annually up to 5 years

  8. Reduction in MR grade

    Measured: from baseline to 30 days, 3, 6, 12 months and annually up to 5 years

  9. Atrial septal defects requiring closure

    Measured: 30 days, 3, 6, 12 months and annually up to 5 years

  10. Change in Montreal Cognitive Assessment (MoCa)

    The Montreal Cognitive Assessment is a 30-point test assessing multiple cognitive domains, including short-term memory recall, visuospatial abilities, executive function, attention, concentration, working memory, language, and orientation to time and place. Scores are on a 30-point scale; scores 26 and above indicate normal cognitive function. Lower scores may indicate mild cognitive impairment (scores 19-25), moderate impairment (scores 10-18), or severe impairment (scores less than 10).

    Measured: Discharge and 30 days

  11. Composite of MVARC criteria

    Number of patients who experience composite endpoint events: death due to any cause, repeat hospitalization due to heart failure, disabling stroke, myocardial infarction, life-threatening major bleeding, acute kidney injury, or specific device-related major technical failure issues and complications.

    1. Repeat hospitalization for heart failure c. Disabling stroke d. Myocardial infarction e. Life-threatening major bleeding f. Acute kidney injury g. Specific device-related major technical failure issues and complications

    Measured: 30 days, 3, 6, 12 months and annually up to 5 years

Questions about this trial

What is this clinical trial studying?

A study testing Innovalve TMVR system in people with Mitral Valve Regurgitation (Degenerative or Functional), run by Edwards Lifesciences at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 26 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Absence of implant or delivery related serious adverse events at 30 days (time frame: 30 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jun 2025.
