Sex
All
Target Recruitment
115
Inclusion Criteria
  • ≥18 years of age or ≤80 years of age (male or female) at time of surgery
  • Acute DeBakey type I dissection based on computed tomography angiography (CTA) and diagnosed ≤14 days from of the index event
  • Presence of malperfusion (cerebral, visceral, renal, spinal cord, and/or peripheral)
Exclusion Criteria
  • Other medical condition that is associated with limited life expectancy <2 years (e.g., cancer, congestive heart failure)
  • Pregnant or breastfeeding.
  • Unwilling to comply with the follow-up schedule
  • Institutionalized due to administrative or judicial order
  • Unwilling to accept blood transfusions for any reason
  • Coronary malperfusion
  • In circulatory shock (i.e., systolic blood pressure <90 mmHg) at time of screening
  • In extreme hemodynamic compromise requiring cardiopulmonary resuscitation at time of screening
  • Suspicion of bowel necrosis (as determined by the implanting physician based on imaging observations, peritoneal signs, surgical exploration, elevated serum lactate levels, low pH, and/or acidosis)
  • Clinical or radiographic signs of bowel infarction or gastrointestinal hemorrhage
  • Base deficit > -10 mmol/L or -10 mEq/L
  • American Society of Anesthesiologists risk class V (i.e., moribund patient not expected to live 24 hours with or without operation) or class VI (a declared brain dead patient whose organs are being removed for donor purposes)
  • Previous placement of a thoracic endovascular graft
  • Interventional and/or open surgical procedures 30 days prior to the dissection repair
  • Planned major interventional and/or open surgical procedures 30 days post the dissection repair
  • Systemic infection
  • Uncontrollable anaphylaxis to iodinated contrast (patients with allergy to iodinated contrast but not anaphylaxis may be eligible with appropriate pre-medication, as deemed suitable by the Investigator)
  • Known allergy(ies) to nitinol and/or polytetrafluoroethylene
  • Inability to obtain CT angiograms for follow-up
  • Previously diagnosed with Marfan syndrome, Ehlers-Danlos syndrome, or Loeys-Dietz syndrome based on laboratory genetic testing
  • Diagnosed with acute myocardial infarction in the 30 days prior to the dissection diagnosis
  • Diagnosed with severe and catastrophic neurological complications in the 30 days prior to the dissection diagnosis (namely, obtundation or coma)
  • Current Stage 5 end stage chronic kidney disease (eGFR ≤ 15 mL/min)
  • History of bleeding disorder (i.e. hemophilia)
  • A primary entry tear that extends into the arch or distal to the left subclavian artery
  • Need for a total aortic arch replacement and/or repair, or reconstruction, of any part of the arch, and branch vessels (including extra-anatomic bypass of the branch vessels), for any reason as deemed necessary by the Investigator
  • Any pathology of mycotic origin
  • Aortic fistulous communication with non-vascular structure (e.g., esophagus, bronchial)
  • Extensive thrombus or calcifications in the aortic arch, as defined by CTA
  • Excessive tortuosity precluding safe passage of the AMDS, as defined by CTA
  • Descending thoracic aneurysm involving the proximal third (one-third) of the descending aorta and measuring >45 mm in diameter
  • Aortic arch aneurysm >50 mm in diameter

Study & Design

INTERVENTIONAL
Study Design
SINGLE_GROUP
Arm && Interventions
GroupInterventionDescription
Acute DeBakey Type I DissectionAMDSIn eligible patients, the ascending aorta is transected and removed in a routine standard of care manner utilizing hypothermic circulatory arrest; the operator will leave at least 10 mm (1.0 cm) aortic tissue proximal to the innominate artery. AMDS is pre-loaded onto the delivery system and is delivered into the true lumen through the open distal aorta and implanted according to the instructions for use.
