About this study

Official title: A Single-Center, Open-Label Study to Assess the Severity of Mitral Regurgitation With Multimodality Imaging

To investigate to assess the severity of mitral regurgitation by multimodality imaging.

Read the detailed description

In the single-center and open-label study, the researcher will compare the changes of ultrasonic cardiography (UCG) parameters when patients in fasting, anaesthesia and rehydration firstly. The aims are to clarify the effect of fasting and anaesthesia on the assessment of mitral regurgitation (MR) severity and the corrective effect of intravenous rehydration. The researcher then will investigate the correlation and consistency of multimodality imaging in assessing the severity of mitral regurgitation. The aim is to acquire more accurate, objective and reproducible parameters, to provide new solution for the precise assessment of MR severity and to guide the selection of clinical treatment and timing.

Being tested
rehydration, UCG, CMR, fasting
Keywords

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • rehydrationOther

    The fasting patients in anaesthetised receive saline rehydration to maintain central venous pressure of 6-8 cmH2O when undergoing UCG.

  • UCGDiagnostic test

    UCG is the most common imaging modality to assess the mitral regurgitation in clinical and also is the primary modality recommended by guidelines. At the beginning of the study, the fasting patients receive UCG in the different situation such as pre-anaesthetic, post-anaesthetic and post-rehydration.

  • CMRDiagnostic test

    CMR may be more accurate than UCG in assessing MR severity. In another time, the patients receive CMR.

  • fastingOther

    At the beginning of the study, the patients need to fast when receive UCG.

Questions about this trial

What is this clinical trial studying?

A study testing rehydration, UCG and CMR in people with Mitral Regurgitation, run by Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University at 1 site in China.

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 13 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: status not confirmed, as of the sponsor's last update on 20 Feb 2024. 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 China. 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?

Results are not available in the source record.

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

Contact Maohuan Lin, PhD (13580575861, maohuan_lin@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

effective regurgitant orifice area (EROA) (time frame: 1 day during an examination). 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?
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 20 Feb 2024.
