About this study

Official title: Multi-center Trial of Transcatheter Edge-to-edge Mitral Valve Repair With ValveClamp System in High Risk Patients With Degerative Mitral Regurgitation

The ValveClamp (Hanyu Medical Technology, Shanghai, China) is the first edge-to-edge mitral valve repair system for interventional operation in China, which is composed of the front clamp, the rear clamp and the closed ring. The purpose of the multi-center trial is to evaluate the safety and efficacy of the ValveClamp for degenerative mirtal regurgistation.

Read the detailed description

The transcatheter edge-to-edge mitral valve repair device MitraClip (Abbott Vascular, Santa Clara, CA, USA) is the most mature device for mitral regurgitation. Another transcatheter edge-to-edge mitral valve repair device, the PASCAL system, has been shown to be feasible to reduce MR severity. Both the MitraClip and PASCAL devices need a complex steerable deliver system and thus complex process to steer the device to mitral valve. An easy-to-operate transcatheter edge-to-edge mitral valve repair system (ValveClamp) with larger coaptation width was thus recently developed in China. The ValveClamp (Hanyu Medical Technology, Shanghai, China) is the first edge-to-edge mitral valve repair system for interventional operation in China, which is composed of the front clamp, the rear clamp and the closed ring. The purpose of the multi-center trial is to evaluate the safety and efficacy of the ValveClamp for degenerative mirtal regurgistation.

What is being measured

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

  1. The device success rate

    freedom from the composite end point of death from any cause, surgery for valve dysfunction, and MR ≥3+ at one month.

    Measured: 12months

Secondary outcomes (7)
  1. Incidence of adverse cardiovascular events

    death, severe arrhythmia, pericardial tamponade, emergency surgery, cardiac shock, endocarditis, bleeding , and other complications caused by procedure

    Measured: immediate post-operation

  2. Incidence of deaths

    All cause deaths (cardiac death, and non cardiac death) or strokes

    Measured: 1,6,12months

  3. Incidence of mitral valve re-surgery

    Mitral valve re-surgery because of the failure of operation, embolism, clamp's falling off.

    Measured: 1,6,12months

  4. Grading of mitral regurgitation by echocardiography

    The echocardiographic analysis was performed according to the American Society of Echocardiography guidelines. The severity of MR was graded as none or trac e (0+), mild(1+), moderate(2+), moderate to severe (3+) or severe (4+) by using the EVERST criteria.

    Measured: 1,6,12months

  5. New York Heart Association (NYHA) class

    The NYHA cardiac function class containing the levels of Ⅰ, Ⅱ, Ⅲ, Ⅳ, relies on the concept of ordinary physical activities. Class Ⅰ means that patients have cardiac disease but without the resulting limitations of physical activity. Class Ⅱ means that patients have cardiac disease resulting in slight limitation of physical activity. Class Ⅲ refers to that patients have cardiac disease resulting in marked limitation of physical activity. Class Ⅳ refers to that patients have cardiac disease resulting in inability to carry on any physical activity without discomfort.

    Measured: 1,6,12months

  6. brain natriuretic peptide

    BNP is a kind of laboratory blood test index to reflect the cardiac function.

    Measured: 1,6,12months

  7. severe adverse events

    Severe adverse events include injury of mitral valves, re-inpatient for poor cardiac function and other severe adverse events.

    Measured: 1,6,12months

Questions about this trial

What is this clinical trial studying?

A study testing ValveClamp in people with Evaluate the Safety and Efficacy of the ValveClamp, run by Shanghai Zhongshan Hospital 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 6 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 27 May 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 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 Wenzhi Pan, M.D. (13774475922, peden@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The device success rate (time frame: 12months). 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 27 May 2020.
