About this study

Official title: Prospective Clinical Trial Evaluating the Safety and Efficacy of Prosthetic Polymer Heart Valves for the Treatment of Aortic Valve Disease

The purpose of this study is to conduct the initial clinical investigation of the HeartHill Medical's polymer aortic valve, namely PoliaVavle,to collect evidence on the device's safety and performance.

Read the detailed description

The polymer aortic valve, PoliaValve, from HeartHIll Medical, is indicated as a replacement for patients with severe aortic valve disease, including severe aortic stenosis, severe aortic regurgitation, or both. These patients will be included in the study after systematic assessment that the subjects meet the criteria for inclusion in the study.

What is being measured

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

  1. Compliance rate of prosthetic valve function

    The compliance rate of prosthetic valve function evaluation at 1 month after surgery. The standard of prosthetic valve function is as follows: prosthetic valve pressure difference <20mmHg or peak flow rate < 3m/s, no moderate or above intravalvular regurgitation or paravalvular leakage), and no reintervention is required.

    Measured: 1 month following patient enrollment completion

  2. Surgery success rate

    Event-free survival of the prosthetic valve at 1 month postoperatively. Prosthetic valve degeneration includes stenosis and/or regurgitation due to structural abnormalities of the valve itself (e.g., leaflet tears, detachment, calcification, fibrosis, deformation of the valve frame, and fracture of the material of the connecting parts between the valve components) (referred to as structural valve degeneration), as well as dysfunction due to infective endocarditis, perivalvular leakage, valve prosthesis-patient mismatch, valve displacement, and leaflet thrombosis (referred to as nonstructural valve degeneration). Prosthetic valve degeneration usually consists of three stages, with the first stage consisting of morphological evidence of valve degeneration and structural abnormalities, before significant hemodynamic changes are evident.

    Measured: 1 month following patient enrollment completion

Secondary outcomes (6)
  1. EOA

    Use echocardiography to evaluate the effective valve orifice area(EOA) to assess the hemodynamic Performance.

    Measured: baseline and 1 month, 6months, 12months following patient enrollment completion

  2. Mean transvalvular pressure difference

    Use echocardiography to measure the mean transvalvular pressure difference.

    Measured: baseline and 1 month, 6months, 12months following patient enrollment completion

  3. Peak flow velocity

    Use echocardiography to measure the peak flow velocity.

    Measured: baseline and 1 month, 6months, 12months following patient enrollment completion

  4. Regurgitation

    Evaluate the presence or absence of intravalvular or paravalvular regurgitation during the follow-up period by echocardiography.

    Measured: baseline and 1 month, 6months, 12months following patient enrollment completion

  5. New York Heart Association Assessment (NYHA)

    Evaluate New York Heart Association Assessment (NYHA) to see Heart Function Improvement.

    Measured: baseline and 1 month, 6months, 12months following patient enrollment completion

  6. BNP or NT-proBNP

    Measure BNP or NT-proBNP to get the changes in postoperative cardiac function from baseline.

    Measured: baseline and 1 month, 12months following patient enrollment completion

Questions about this trial

What is this clinical trial studying?

A study testing PoliaValve (Aortic) in people with Aortic Valve Disease and Aortic Valve Stenosis, run by Suzhou Hearthill Medical Technology Co.,LTD 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 5 inclusion and 14 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: enrolling by invitation, as of the sponsor's last update on 16 Dec 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?

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?

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?

Compliance rate of prosthetic valve function (time frame: 1 month following patient enrollment completion). 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 16 Dec 2024.
