About this study

Official title: Efficacy and Safety Evaluation of Transcatheter Pulmonary Valve Implantation for Right Ventricular Outflow Tract (RVOT) Stenosis After Congenital Heart Defect Surgical Correction Complicated With Severe Pulmonary Regurgitation

A prospective, non-randomized, multi-center clinical study of the Venus P-valve for the treatment of RVOT stenosis with pulmonary regurgitation after surgery of congenital heart defect.

Read the detailed description

The aim of this protocol is to assess the efficacy, safety and performance of Venus P-valve.

Patients between 18-60 years with RVOT stenosis and moderate to severe pulmonary regurgitation (≥3+) who have undergone trans-annular patch repair of their RVOT, cardiac magnetic resonance (CMR) screening right ventricular end-diastolic volume index (RVEDVI) between 130-160mL/m2.

Post-procedure follow-ups will be scheduled at 24 hours, 30 days, 6 months and 12 months.

What is being measured

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

  1. Improvement rate of RVEDV at 6 months post-procedure.

    The improvement is defined as the RVEDVI≤108mL/m2 measured with CMR.

    Measured: At 6 months post-implantation of Venus-P valve

Secondary outcomes (1)
  1. Safety Endpoints

    Accumulated occurrences (rate of patients/year) of procedure-related clinical events (death, severe arrhythmias, cardiac tamponade, RVOT or pulmonary artery perforation or rupture, cardiac shock, endocarditis from the date of valve implantation up to 12 months post-procedure or bleeding due to use of heparin/aspirin at 48 hours post-procedure assessed per protocol.

    Occurrence of all deaths (cardiac death, non-cardiac deaths and other deaths) and stroke one year post-procedure.

    Measured: From the date of implantation until 12 months post-procedure

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Venus P-valve transcatheter implantation in people with Right Ventricular Outflow Tract Stenosis, run by Venus MedTech (HangZhou) Inc. 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 16 inclusion and 12 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 6 Jan 2015. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 David Liu, MD (+86 10 6595 6828 ext. 806, davidliu@coremed.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvement rate of RVEDV at 6 months post-procedure. (time frame: At 6 months post-implantation of Venus-P valve). 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 6 Jan 2015.
