Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Weight ≥ 20 kg (44 lbs.)
- Dysfunctional RVOT conduit or previously implanted valve in the pulmonic position with a clinical indication for intervention and with a landing zone diameter ≥ 16.5 mm and ≤ 29 mm immediately prior to study device insertion as per the Instructions for Use
- Subject presents with at least moderate PR and/or mean RVOT gradient ≥ 35 mmHg.
- The subject/subject's legally authorized representative has been informed of the nature of the study, agrees to its provisions and has provided written informed consent.
Exclusion criteria
- Active infection requiring current antibiotic therapy (if temporary illness, subject may be a candidate 2 weeks after discontinuation of antibiotics)
- History of or active endocarditis (active treatment with antibiotics) within the past 180 days
- Leukopenia, anemia, thrombocytopenia or any known blood clotting disorder
- Inappropriate anatomy for femoral introduction and delivery of the study valve
- Need for concomitant atrial septal defect or ventricular septal defect closure or other concomitant interventional procedures other than pulmonary artery or branch pulmonary artery stenting or angioplasty
- Angiographic evidence of coronary artery compression that would result from transcatheter pulmonic valve implantation (TPVI)
- Interventional/surgical procedures within 30 days prior to the TPVI procedure.
- Any planned surgical, percutaneous coronary or peripheral procedure to be performed within the 30 day follow-up from the TPVI procedure.

- Major or progressive non-cardiac disease resulting in a life expectancy of less than one year
- Known hypersensitivity to aspirin or heparin and cannot be treated with other antiplatelet and/or antithrombotic medications
- Known hypersensitivity to cobalt-chromium, nickel or contrast media that cannot be adequately premedicated
- Participating in another investigational drug or device study that has not reached its primary endpoint.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
