About this study

Official title: Open, Prospective, Multicenter Study of the Safety and Efficacy of "UniLine" Epoxy-treated Prosthesis Made From Xenopericardium in the Treatment of Isolated Aortic and Mitral Valve Diseases

The goal of this open, prospective, multicenter study is analyze long-term outcomes of aortic/mitral valve replacement using the "UniLine" bioprosthesis in patients with acquired aortic or mitral valve diseases.

Main research objectives:

Read more

To analyze long-term (up to 12 years) outcome of aortic or mitral valve replacement using the "UniLine" bioprosthesis.

To study the hemodynamic characteristics of normally functioning "UniLine " prostheses in the mitral or aortic valve position based on the transthoracic echocardiography data.

To assess the number, type, time frames of dysfunctions of UniLine bioprostheses and the results of their treatment.

To analyze the frequency of major serious adverse events associated with the "UniLine" bioprosthesis or procedure.

Read the detailed description

Acquired heart diseases (AHDs) remain one of the most frequent causes of cardiac mortality and disability. In Russia, this kind of disease accounts for 7 to 25 % of all cardiovascular diseases, and is third most common cause of heart failure.

Heart valve replacement using a prosthetic heart valve remains the main and most effective method of treatment of AHDs. In Russia, AHDs are treated in more than 40 subjects by specialists from 92 medical institutions. Valve replacements, being high-tech methods of treatment, most effectively prolong the life of patients. Timely correction of AHD allows 75-95 % of patients to return to a normal lifestyle.

The aim of this study is to evaluate the safety and effectiveness of the "UniLine" epoxy-treated bioprosthesis in the treatment of isolated mitral or aortic heart valve diseases.

The expected clinical benefit involves the treatment of valvular disease with restoration of intracardiac hemodynamics during implantation of the "UniLine " bioprosthetic valve, followed by remodeling of the heart chambers, which should lead to an improvement in heart function and quality of life of the patient.

The expected risks are associated with taking anticoagulant therapy during the first three months after implantation, or as a result of prolonged anticoagulant therapy, in the presence of concomitant rhythm disturbances, and consist in the possibility of hemorrhagic or thromboembolic complications.

What is being measured

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

  1. Safety of the Bioprosthetic Valve

    Safety of using the bioprosthesis is defined as the absence of major adverse events related to the device or procedure, assessed using the following clinical phenomena:

    1. Fatal outcome: a) all-cause death; b) related to cardiovascular diseases; c) related to the dysfunction of the prosthesis.
    2. Life-threatening bleeding.
    3. Any dysfunction associated with the bioprosthesis (stenosis, regurgitation), migration of the device, thrombosis or other complication requiring surgical intervention.
    4. Any dysfunction associated with the bioprosthesis that does not require surgical intervention.
    5. Myocardial infarction (or stroke) or progression of a chronic form of ischemia requiring percutaneous coronary intervention or coronary artery bypass graft surgery
    6. Stroke

    Measured: 12 years since the replacement surgery

  2. Long-Term Durability of the Bioprosthetic Valve

    It will be evaluated by measuring the hemodynamic characteristics of the prosthetic valve, assessed by echocardiography: maximum, average gradients and effective orifice area (absolute and indexed values).

    Measured: 12 years since the replacement surgery

Secondary outcomes (1)
  1. Hemodynamic characteristics of the Bioprosthetic Valve

    They will be assessed by using echocardiography: maximum, average gradients and effective orifice area (absolute and indexed values).

    Measured: 12 years since the replacement surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Aortic Valve Disease and Mitral Valve Disease, run by Closed Joint-Stock Company NeoCor at 1 site in Russia.

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 5 inclusion and 8 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: looking for participants now, as of the sponsor's last update on 25 Sep 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 Russia. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Evgeny Bazdyrev, MD, PhD (+7-3842-64-42-40, clinicresearch@kemcardio.ru), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety of the Bioprosthetic Valve (time frame: 12 years since the replacement surgery). 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?
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 25 Sep 2024.
