Read the detailed description

A prospective, single-center, single-group follow-up study of transcatheter aortic valve replacement with A² Flex and commissural alignment technology in severe aortic stenosis by Peijia Medica.Patients are seen at pre and post procedure, discharge, 30 days. The main follow-up included clinical symptoms and signs, cardiac ultrasound, CT, etc. The outcome include immediate device success, procedure success and device sucess. The secondary end points include :1) Immediate postoperative ultrasound evaluation of different sinus valve implantation depths.2) realization rate of commissural alignment was evaluated by ultrasound immediately after operation.3) the incidence of ≥ moderate paravalvular regurgitation assessed by ultrasound at 30 days after surgery.

  1. CT assessment of different sinus valve implantation depths at 30 days after surgery.5) CT was performed 30 days after operation to evaluate the realization rate of commissural alignment and coronary artery alignment

Study groups in NCT06721676
Study groupRoleWhat they receive
A single arm studyExperimentalThe experimental apparatus consisted of artificial aortic valve, transporter and grip-loading system.the transporter has A2 flex function to improve coaxiality and commissural aligment to reduce coronary occlusion
Receives: Device: transcatheter aortic valve replacement in severe aortic stenosis

What is being measured

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

  1. Device success rate

    Device success is defined as - Vascular access, artificial aortic valve delivery and release were successful, and the delivery catheter was successfully withdrawn. - The artificial aortic valve was implanted in an anatomically accurate position. - The artificial aortic valve met the expected requirements (mean transvalvular pressure difference < 20mmHg or maximum flow rate < 3m/s; Doppler velocity index >_0.25,and less than moderate aortic regurgitation)

    Measured: at 30 days

Questions about this trial

What is this clinical trial studying?

A study testing transcatheter aortic valve replacement in severe aortic stenosis in people with Aortic Stenosis Symptomatic, run by Peijia Medical Technology (Suzhou) 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: opening soon, as of the sponsor's last update on 6 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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Device success rate (time frame: at 30 days). 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 NCT06721676, which also lists 3 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 6 Dec 2024.
