Study summary

This study is designed as a prospective, multicenter, non-randomized, single arm study to assess the safety and effectiveness of the Large Diameter Advanta™ V12 Covered Stent for stent implantation in coarctations of the aorta.

Read the detailed description

The performance metric for comparison is based on data from the Congenital Cardiovascular Interventional Study Consortium (CCISC) as reported by Golden and Hellenbrand [1]. The CCISC experience from 1989 to 2005 shows a true procedural success rate of 98.6%.

The patient population will be subjects with coarctation of the aorta. A total of 70 subjects, children, adolescents and adults, will be enrolled at up to 15 study sites. Baseline clinical and angiographic assessment will determine the subject's eligibility for enrollment in the study. Subjects will continue in the study for long term annual follow-up through 3, 4, and 5 years.

Inclusion criteria

  • Patients with a presence of native or recurrent coarctation of the aorta as confirmed by blood pressure gradient, 2D-echocardiography with Doppler or angiography.
  • Subject weighs a minimum of 30 kg.
  • The peak pressure gradient is ≥20 mmHg systolic blood pressure across the coarctation site.
  • Vessels at access site can accept a minimum size of 9 French for a 12 mm balloon and 11 French for a 14 and 16 mm balloon.
  • Coarctation can be successfully crossed with a guide wire, sheath and device.
  • Diameter of transverse arch distal to left subclavian artery is between 9.5 mm and 20 mm in diameter.
  • Subject is able and willing to adhere to all required follow-up visits and testing.
  • Subject is able and willing to adhere to the required follow-up medication regimen.

Exclusion criteria

Exclusion Criteria:

  • The physician is not able to access the coarctation with standard techniques.
  • Presence of other thoracic aortic arterial lesions or aneurysms requiring treatment within 30 days of the implant procedure.
  • Length of coarctation is greater than 45 mm in length.
  • Connective tissue and genetic disorders, including William, Marfan, Turner, Noonan syndrome.
  • The coarctation has adjacent, acute thrombus.
  • The coarctation was previously treated with a stent.
  • Proximity of the coarctation to an important side branch resulting in crossing of the side branch with the Large Diameter Advanta™ V12 Covered Stent device (e.g. "jailing" of the branch vessel).
  • Subject has a tubular graft, interposition graft, stent graft at or near the coarctation site that would be interfere with delivery, positioning, expansion or stabilization of the Large Diameter Advanta™ V12 Covered Stent
  • Subject has contrast agent that cannot be adequately premedicated, has a hypersensitivity to stainless steel, expanded polytetrafluoroethylene (ePTFE) or has intolerance to antiplatelet, anticoagulant, or thrombolytic medications.
  • Bloodstream infection
  • Subject is pregnant or breastfeeding.
  • Subject has a co-morbid illness that may result in a of less than 1 year.
  • The investigator deems the subject to be an inappropriate candidate for the study.
  • Subject is participating in an study of a new drug, biologic or device at the time of study screening. NOTE: Subjects who are participating in the long term follow-up phase of a previously investigational and now approved product are not excluded by this criterion.
Terms in these criteria, in plain language(3)

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Primary Efficacy

    The mean difference between Diastolic Velocity (DV)/Systolic Velocity(SV) pre and post procedure (i.e. pre procedure DV/SV - post procedure DV/SV) minus the difference between 12 month and post procedure (i.e. 12 month DV/SV - post procedure DV/SV).

    Time frame: 12 month

  2. Primary Safety

    30 day morbidity rate of Major Adverse Events (MAE)and Major Adverse Vascular Events (MAVE)

    Time frame: 30 days of procedure

Secondary outcomes

  1. Secondary Safety

    Device success, defined as the successful delivery and deployment of the study stent and intact retrieval of the delivery system.

    Time frame: procedural (time zero)

  2. Secondary Safety

    No post procedural stent migration, where migration is defined as displacement of the stent \>20mm from an established anatomical landmark verified during deployment.

    Time frame: 12 month

  3. Secondary Safety

    Major Adverse Events (MAE)and Major Adverse Vascular Events (MAVE)

    Time frame: 12 months

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 Jul 2, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
