What is being measured

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

  1. Co-Primary Endpoint #1: Technical Success

    All of the qualifying criteria are met (in the absence of surgical conversion or mortality, type I or type III endoleak, branch occlusion, or graft limb obstruction):

    • Successful access to the arterial system using remote arterial exposure, percutaneous technique, or open surgical conduits at index procedure.
    • Successful delivery and deployment of the aortic stent graft and all modular stent graft components at index procedure
    • Successful side branch catheterization and placement of bridging stents with restoration and maintenance of flow in all intended target vessels at final completion angiography.
    • Absence of type I or type III endoleaks at final completion angiography.
    • Patency of all aortic modular stent graft components and intended side branch components at final completion angiography.

    Measured: Time of index procedure

  2. Co-Primary Endpoint #2: Clinical Success

    All of the following qualifying criteria are met from the initiation of the index procedure through 12 months post-index procedure:

    • Technical success
    • Absence of death from the initial procedure, secondary intervention, or aorta-related cause
    • Absence of persistent type I or type III endoleak
    • Absence of lesion enlargement >5 mm
    • Absence of device migration >10 mm

    • Absence of lesion rupture
    • Absence of conversion to open surgical repair
    • Absence of permanent paraplegia (see definition below)
    • Absence of disabling stroke (see definition below)
    • Absence of "loss of function" or "end-stage renal disease" stage according to the RIFLE Classification following the index procedure

    Measured: Index procedure through 12 months

Secondary outcomes (15)
  1. Target Vessel Technical Success

    Successful catheterization and stent placement in all intended target vessels. Note: For this study, technical success will be reported for the overall procedure and specifically for the vessels targeted for treatment with the branch components (this "target vessel technical success" definition).

    Measured: 30 days, 6 months, annually through 10 years

  2. Secondary Clinical Success

    Initial clinical success that is interrupted by a treatment failure and is successfully corrected with secondary reintervention (e.g., a patient undergoes a successful treatment of a type I, II, or III endoleak).

    Measured: 30 days, 6 months, annually through 10 years

  3. Assisted Primary Clinical Success

    Clinical success that is obtained initially and continuously maintained with additional secondary reinterventions thus no interruption to initial clinical success.

    Measured: 30 days, 6 months, annually through 10 years

  4. Thirty-Day Mortality

    Any death that occurs during the procedure, within the index procedure hospital stay, or within the first 30 days post-index procedure.

    Measured: 30 days

  5. Lesion-Related Mortality

    Any death that occurs within the first 30 days, or any death that results from lesion rupture, aorta-related complications (e.g., infection, occlusion, dissection, hematoma), or a complication of a secondary intervention.

    Measured: 30 days, 6 months, annually through 10 years

  6. Major Adverse Events (MAEs)

    Includes any of the following:

    • All-cause mortality;
    • Myocardial infarction resulting in severe hemodynamic dysfunction necessitating resuscitation, cardiac arrest, or fatal outcome;
    • Respiratory failure requiring prolonged (>24 hours from anticipated) mechanical ventilation or reintubation;
    • Renal function decline characterized by one or more of the following:
    • >50% reduction in baseline Estimated Glomerular Filtration Rate (eGFR); or,
    • New-onset dialysis;
    • Bowel ischemia requiring surgical resection or not resolving with medical therapy;
    • Permanent paraplegia (see "permanent paraplegia" definition below)
    • Any major stroke

    Measured: 30 days, 6 months, annually through 10 years

  7. Secondary interventions

    Any Reintervention: Any repeated vascular or nonvascular procedure on the index device (TAMBE Device or any stent or stent graft in contact with any TAMBE component).

    • Note: Reintervention will be classified as "major", "minor", or "nonvascular" based on the definitions below.

    Major Reintervention: Deployment of proximal or distal extensions, removal of the device, use of thrombectomy or thrombolysis, and any major open surgical procedure.

    Minor Reintervention: Endovascular procedures (percutaneous transluminal angioplasty, atherectomy, stenting) without thrombectomy or thrombolysis, interventions to treat branch vessel stenosis, interventions to treat type II endoleaks or branch-related endoleaks, and minor surgical revisions (patch angioplasty) of the access vessels.

    Nonvascular Reinterventions: Any reinterventions that would not be considered "major reintervention" or "minor reintervention" based on the above definitions.

    Measured: Time of index procedure

  8. Intraprocedural Complications

    Any vessel perforation, dissection, or occlusion during target vessel cannulation and/or stenting.

    Measured: 30 days, 6 months, annually through 10 years

  9. Kink

    Objective documentation of demonstrable angulation (localized angle of less than 90 degrees when measured along the centerline) in any of the stent components or native target vessel

    Measured: 30 days, 6 months, annually through 10 years

  10. Stenosis

    Objective documentation of presence of narrowing with demonstrable flow in any of the components

    Measured: 30 days, 6 months, annually through 10 years

  11. Occlusion

    Objective documentation of presence of complete stent occlusion with or without minimal flow into a targeted vessel.

    Note: Occlusions will be stated if they occurred in the aortic component, in a branch component, or in a contralateral leg component used to treat the aortic disease.

    Measured: 30 days, 6 months, annually through 10 years

  12. Target Vessel Instability

    Any death or rupture related to side branch complication (e.g., endoleak) or any secondary intervention indicated to treat a branch-related complication, including endoleak, disconnection, kink, stenosis, occlusion, or rupture.

    Measured: 30 days, 6 months, annually through 10 years

  13. Secondary Patency

    Endovascular restoration of patency after occlusion of the side branch, stent, or stent graft has already occurred.

    Note: Conversion to bypass or inability to treat by endovascular means defines loss of secondary patency.

    Measured: 30 days, 6 months, annually through 10 years

  14. Primary Assisted Patency

    Endovascular intervention performed to maintain patency in the presence of stenosis before occlusion.

    Measured: 30 days, 6 months, annually through 10 years

  15. Primary Patency

    Uninterrupted patency with no occlusion or procedure performed to maintain patency on the stent or native target vessel.

    Note: Interventions intended to treat endoleak or stent disconnection do not count as loss of primary patency.

    Measured: 30 days, 6 months, annually through 10 years
