About this study

Official title: Association of Global Longitudinal Strain and Global Constructive Work With Cardiac Performance and Clinical Outcome One Year After MitraClip Implantation in Functional Mitral Regurgitation

The aim of this study is i) to evaluate left ventricular global longitudinal strain and myocardial work in patients with heart failure and severe functional mitral regurgitation one year after MitraClip implantation and compare these variables with patients treated with optimal medical treatment and ii) to find echocardiographic predictors of clinical response and reverse left ventricular remodeling at one-year follow up.

Read the detailed description

This study is one of the first in terms of publication. As far as the investigators know there are few papers with small series of patients regarding echocardiographic parameters and strain imaging in patients with functional mitral regurgitation (MR) and MitraClip. As the investigator's goal is to assess the potential impact of the MitraClip on myocardial deformation indexes, at the end of the study a direct comparison of changes of echocardiography markers -at one year follow up- between the control and device group will be performed. The changes in myocardial deformation markers will be associated with the respective changes in Brain-natriuretic peptide (BNP) levels, New York Heart Association (NYHA) class status, 6-minute walking distance (6MWD) and left ventricle (LV) volumes at follow -up. The investigators also aim to identify baseline prognostic echocardiography markers for the prediction of clinical improvement and LV reverse remodeling after successful edge-to-edge repair in functional MR patients during one year follow up. In specific, in this study the investigators will measure the 2-Dimension (2D) strain values of the left ventricle and left atrium (global longitudinal strain-GLS of the LV and Peak Atrial longitudinal strain - PALS of the left atrium) at baseline and at one year follow up, they will appreciate the LV myocardial work and all its components (Global Work Index-GWI, Global Constructed Work-GCW,Global wasted work-GWW and Global Work Efficiency-GWE) of the left ventricle and finally they will evaluate the baseline variables as predictors of reverse LV remodeling defined by reduction of left ventricle end-diastolic and end-systolic volume at one-year follow up.

Questions about this trial

What is this clinical trial studying?

An observational study of Mitral Regurgitation and Heart Failure, run by University of Athens at 1 site in Greece.

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 5 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 6 Jan 2020. 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 Greece. 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?

Changes of LV volumes (time frame: one year). The study lists 2 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 NCT04218578, 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 6 Jan 2020.
