Retrospective Real-World Data Collection of the Conformable GORE® TAG® Thoracic Endoprosthesis When Used in Frozen Elephant Trunk Procedures for Treatment of Aortic Aneurysms and Dissections

An observational study in Dissection of Aorta, Aneurysm Aortic and Frozen Elephant Trunk, sponsored by W.L.Gore & Associates. Not yet recruiting. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-08-03.

Aortic Dissection — the first condition term the registry derived for this study.

Aortic Aneurysm
Why
  1. The registry often attaches Aortic Dissection to studies about something else, and this study's title and listed conditions do not name it.
  2. The study's listed conditions name Aortic Aneurysm.
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 →

Study summary

Retrospective, multicenter, single-arm registry data collection designed to characterize outcomes in patients treated with the Conformable GORE® TAG® Thoracic Endoprosthesis deployed in an antegrade fashion as part of a frozen elephant trunk (FET) procedure

Read the detailed description

Retrospective, multicenter, single-arm registry data collection designed to characterize outcomes in patients treated with the Conformable GORE® TAG® Thoracic Endoprosthesis deployed in an antegrade fashion as part of a frozen elephant trunk (FET) procedure and to assess the safety and performance of the Conformable GORE® TAG® Thoracic Endoprosthesis deployed antegrade as part of a FET procedure. This will be evaluated using real-world data and Computed Tomography (CT) imaging abstracted through retrospective chart review.

Lead sponsor

W.L.Gore & Associates is the lead sponsor of 96 studies on the registry; 20 are open to participants now.

Compared within Aortic Aneurysm, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Aortic Dissection. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Study population

The patient pool from which sites will screen for enrollment is comprised of patients with history of thoracic aortic disease that required surgical repair using a FET procedure. For qualifying patients with dissections, they will be enrolled into either of the following cohorts:

  • Hyperacute: onset of symptoms must be documented to be \<24 hours prior to the date of the procedure.
  • Acute: onset of symptoms must be documented to be 1-14 days prior to the date of the procedure.
  • Subacute: onset of symptoms must be documented to be 15-90 days prior to the date of the procedure.
  • Chronic: onset of symptoms must be documented to be more than 90 days prior to the date of the procedure.

Those patients who meet all inclusion and no exclusion criteria, will be eligible for enrollment in this retrospective study.

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. Treated for aneurysm or dissection using antegrade deployed Conformable GORE® TAG® Thoracic Endoprosthesis (CTAG) device at least 12 months prior to date of enrollment.
  2. Age ≥ 18 years at the time of the index procedure.
  3. Proximal extent of the Conformable GORE® TAG® Thoracic Endoprosthesis (CTAG) device is sutured to the aorta and/or distal aspect of the surgical graft.
  4. Form (ICF) is signed by the subject or a legally authorized representative, or a waiver of consent is granted by the IRB of record and appropriately documented by the enrolling site.

Exclusion criteria

Exclusion Criteria:

  1. Any modification performed on the CTAG Device, excluding suturing.
  2. Procedure performed in the setting of infection requiring treatment with parenteral anti-infective medication.
  3. Pregnant at the time of the index procedure.
  4. Aneurysm or Subacute / Chronic Dissection cases (onset of symptoms ≥15 days prior to the date of the procedure) with documented aortic rupture at the time of the index procedure.
Terms in these criteria, in plain language(1)

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.

What researchers measure

Primary outcomes

  1. MAE freedom within one year (365 days) post-implant

    The primary endpoint will be measured as freedom from the composite of the following major adverse events (MAE) occurring within one year (365 days) post-implant: * Permanent Stroke * Permanent Paraplegia/ Paraparesis * Mortality * Reoperation

    Time frame: From date of index procedure through 365 days post implant

Secondary outcomes

  1. Freedom from imaging outcomes within the 12-Month analysis window

    The secondary endpoints will be measured as freedom from each of the following imaging outcomes within the 12-Month analysis window unless specified: * Failed Patency (within one year (365 days) post-implant) * Pseudoaneurysm (within one year (365 days) post-implant) * Increase in Aortic Diameter * Device Integrity * Device Migration * Type IA Endoleak * Type IB Endoleak * Type III Endoleak * Thrombosis of Index Pathology

    Time frame: From the date of the index procedure through end of 12 months analysis window unless otherwise specified

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 Aug 3, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
