About this study
Official title: French National Observatory of Percutaneous Mitral Commissurotomy (PMC) Immediate Score, Scanner, Late Results
The aim of this study is to validate prospectively the predictive score of late results about a diverse population recruited in France and to evaluate the contribution in predicting the outcome of the PMC scanner to study the mitral calcium score and the location of the calcifications.
Read the detailed description
This is a multicenter prospective observational study conducted in French medico-surgical sites.
The Percutaneous Mitral Commissurotomy (PMC) is the standard treatment for Mitral stenosis (MS) in patients with rheumatic favorable characteristics. In Western countries the MS reaches older patients with less favorable characteristics, including the presence of mitral calcifications. Calcifications are a factor of poor outcome of the PMC. The scanner appears as a useful examination for their study but is not carried out systematically. The prediction of late results of the PMC is particularly important in patients with non-ideal characteristics which form a particularly heterogeneous population. A score of late results of the PMC on the wider western series was recently released but has not to date received external validation. In this score, prediction results was multifactorial, with a consideration of paramount clinical factors, but also a prognostic significance of mitral calcifications.
The validation of predictive score of late results of the PMC, with the analysis of calcifications, would better select patients who may best benefit from PMC and those for which the surgical management is preferred.
The aim of this study is to validate an external sample predictive score of the event-free survival in patients who have had a good immediate result of the PMC.
This study, purely observational, does not create any special procedure outside the patient's usual care.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Mitral Stenosis | No specific protocol intervention occurs. All the cares are made as done usually. Patients who may be included are all consecutive patients who agreed to participate in the study and having a PMC in a French medical-surgical centers that perform more than 5 year PMC. All patients undergoing echocardiography with the realization of the score Wilkins and Cormier. Will then be included to validate the result of late score that patients who had a good immediate result of the PMC defined by: mitral valve area ≥ 1.5 cm² and IM ≤ 2/4. Patients with a poor immediate result of the PMC will not be monitored as part of the study but their data will be collected for the description of the population and analysis of immediate results. Patients in the study will receive an annual monitoring as recommended, independently of the study. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Event free survival at 3 years
Measurement of event-free survival after good result of the PMC, observed in our study. The composite endpoint event-free survival is defined as: cardiovascular survival without reoperation on the mitral valve and patient in NYHA I-II at last follow
Measured: 3 years

Questions about this trial
What is this clinical trial studying?
An observational study of Mitral Stenosis, run by French Cardiology Society at 1 site in France.
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: finished, as of the sponsor's last update on 21 Sep 2022. 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 France. 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?
Event free survival at 3 years (time frame: 3 years). 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 NCT02783248, which also lists 11 linked publications.
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 21 Sep 2022.
