About this study

Official title: SEP-study; The Assessment of Normal Values in Stress Echocardiographic Parameters in Patients After Successful Mitral Valve Repair for Organic Mitral Valve Regurgitation

Surgical treatment is the only approach with potentially defined clinical success for organic mitral valve (MV) regurgitation. Recurrent or persistent complaints after initial successful MV repair is a clinical challenge in current practice. Especially when echo parameters at rest are within or near normal ranges and patients presenting disproportionately symptomatic in relation to the observed results. However, while MV regurgitation is a hemodynamic disease, currently used 2-dimensional (2D) transthoracic echocardiography (TTE) at rest lacks information about hemodynamic changes. Physical stress echocardiography is a promising technique to complement nowadays rest TTE in order to improve interpretation of hemodynamic changes. However, normal values for exercise echo are lacking in this postoperative patients cohort. A prospective, observational trial to determine normal values in stress echocardiographic parameters in asymptomatic patients after successful MV repair for organic MV regurgitation, is therefore highly needed.

Purpose of the SEP- study is to determine normal values in stress echocardiographic parameters in asymptomatic patients at least 6 months after successful MV repair for organic MV regurgitation. These normal values for stress echo are of utmost importance to correctly and accurate interpret stress echo results during postoperative follow-up and to improve clinical decision making in patients post MV repair.

What is being measured

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

  1. Echocardiographic parameter: Peak mitral valve mean gradient (mmHg)

    Echocardiographic measured mitral valve mean gradient at peak physical exercise

    Measured: at least 6 months after successful MV repair

  2. Echocardiographic parameter: Peak systolic pulmonary artery pressure (sPAP, mmHg)

    Echocardiographic measured sPAP at peak physical exercise

    Measured: at least 6 months after successful MV repair

  3. Echocardiographic parameter: Increase in mitral valve regurgitation grade (grade 0-4, according to ESC guidelines)

    Echocardiographic measured increase in mitral valve regurgitation at peak physical exercise during physical stress echo, compared to rest echo. Grading of mitral regurgitation will be performed according to the ESC guidelines.

    Measured: at least 6 months after successful MV repair

Secondary outcomes (3)
  1. Echocardiographic parameter: Left ventricular function (LVF, quality description)

    Echocardiographic measured LVF quality at rest and peak physical exercise

    Measured: at least 6 months after successful MV repair

  2. Echocardiographic parameter: Mitral valve area (MVA, cm2)

    Echocardiographic measured MVA at rest and peak physical exercise

    Measured: at least 6 months after successful MV repair

  3. Echocardiographic parameter: Peak mitral valve peak gradient (mmHg)

    Echocardiographic measured mitral valve peak gradient at peak physical exercise

    Measured: at least 6 months after successful MV repair

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Valve Diseases and Mitral Valve Insufficiency, run by UMC Utrecht at 1 site in Netherlands.

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 4 inclusion and 11 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: finished, as of the sponsor's last update on 29 Dec 2015. 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 Netherlands. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Echocardiographic parameter: Peak mitral valve mean gradient (mmHg) (time frame: at least 6 months after successful MV repair). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02371863, which also lists 1 linked publication.

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 29 Dec 2015.
