About this study

Official title: A Continued Access Registry of the Evalve® MitraClip® System: EVEREST II Real World Expanded Multicenter Study of the MitraClip System (REALISM)

Prospective, multicenter, continued access registry of the MitraClip® Cardiovascular Valve Repair System in the treatment of mitral valve regurgitation. Patients will undergo 30-day, 6-month, 12-month, 36-month and 60-month clinical follow-up. The study consists of two arms: a High Risk group (NCT01940120) and a Non-High Risk group (NCT00209274) . Patients that did not meet REALISM High Risk or Non-High Risk eligibility criteria were evaluated for consideration for either Emergency Use (EU) or Compassionate Use (CU).

Read the detailed description

The EVEREST II REALISM study (REALISM study) is a continued access registry designed for continued data collection on the use of Abbott Vascular's MitraClip System (MitraClip® Device) under more "real world" conditions. After the completion of enrollment in the pivotal EVEREST II Randomized Controlled Trial (RCT) NCT00209274 and EVEREST II High Risk Registry Study NCT01940120, continued access to the technology was warranted to collect additional safety and effectiveness data on the MitraClip® Device. This continued access study was approved by FDA on November 21, 2008 (G030064). There are two arms (High Risk and Non-High Risk) in the REALISM study. Patients that did not meet REALISM High Risk or Non-High Risk eligibility criteria were evaluated for consideration for either Emergency Use (EU) or Compassionate Use (CU). Enrollment in the Non-High Risk arm of the study concluded on April 14, 2011 and enrollment in the High Risk arm concluded on December 19, 2013.

REALISM is a prospective, multi-center, study of the safety and effectiveness of an endovascular approach to the treatment of mitral valve regurgitation using the Evalve Cardiovascular Valve Repair System (MitraClip® implant). Patients with moderate-to-severe (3+) or severe (4+) mitral regurgitation (MR), as determined by the site from a transthoracic echocardiogram (TTE), were considered for enrollment in this study. The TTE and a transesophageal echocardiogram (TEE) are used to assess eligibility criteria for MR severity, valve anatomy and left ventricular parameters.

Non-High RiskExperimentalIncludes patients who are candidate for mitral valve repair or replacement surgery, including cardiopulmonary bypass (i.e. non-high risk). The patients who are enrolled in this arm will undergo percutaneous mitral valve repair using MitraClip® implant. This arm was evaluated as a separate study NCT00209274.
Receives: Device: MitraClip® implant
High RiskExperimentalIncludes patients with a predicted procedural mortality risk calculated using the Society For Thoracic Surgeon (STS) surgical risk calculator of ≥12% or, in the judgment of a cardiac surgeon, the patient is considered a high risk surgical candidate due to the presence of pre-defined risk factors. The patients who are enrolled in this arm will undergo percutaneous mitral valve repair using MitraClip® implant. This arm was evaluated as a separate study NCT01940120.
Receives: Device: MitraClip® implant
Compassionate UseExperimentalPatients that did not meet REALISM High Risk or Non-High Risk eligibility criteria were evaluated for consideration for either Emergency Use (EU) or Compassionate Use (CU).

    Class IV: Patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of cardiac insufficiency or of the anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort is increased.

    Measured: 4 years

    Class II: Patients with cardiac disease resulting in slight limitation of physical activity. Patients are comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea, or anginal pain.

    Class III: Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary physical activity causes fatigue, palpitation dyspnea, or anginal pain.

Questions about this trial

What is this clinical trial studying?

A study testing MitraClip® implant in people with Mitral Valve Insufficiency and Mitral Valve Regurgitation, run by Abbott Medical Devices at 38 sites in United States.

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 20 inclusion and 36 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 4 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 38 sites in United States. 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?

Yes. Results are posted in the registry (first posted 19 Jun 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Major Adverse Events (time frame: 30 days). 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 NCT01931956, which also lists 6 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 4 Dec 2018; AzTrials last refreshed its copy on 6 Nov 2026.
