Evaluation of the GORE PV1 Device in Patients With Pulmonary Valve Dysfunction

An interventional study of GORE PV1 in Heart Defects, Congenital, Tetralogy of Fallot and Pulmonary Valve Insufficiency, sponsored by W.L.Gore & Associates. Active, not recruiting at 3 sites in United States. Open to participants aged 5 Years and older. Per ClinicalTrials.gov, last updated 2026-02-05.

Registry
Heart Defects, Congenital — the first condition term the registry derived for this study.

Tetralogy of Fallot
Why
  1. The study's listed conditions name Tetralogy of Fallot, a narrower term within Heart Defects, Congenital.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Accepts healthy volunteers
No

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. A symptomatic or appropriate asymptomatic subject with a native or repaired right ventricular outflow tract requiring reconstruction with a valved conduit
  2. Age ≥5 years at the time of signature.

Note: Additional Inclusion Criteria may apply

Exclusion criteria

Exclusion Criteria:

  1. An artificial valve at another position or will need an artificial valve at another position (i.e. replacement at the time of index procedure or anticipated within 3 years).
  2. Subjects with previously implanted pacemaker (including defibrillators).
  3. Major or progressive non-cardiac disease (liver failure, renal failure, cancer) that has a of less than one year.

Note: Additional Exclusion Criteria may apply

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2018 to primary completion in Apr 2020, 22 months.

Of 25 interventional studies with no phase under Tetralogy of Fallot, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 61. This study's 22 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 5, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
