Clinical Trial Summary

Prospective, non-randomized, multicenter clinical investigation to assess the safety and effectiveness of AMDS in the treatment of patients with acute DeBakey type I dissection, with evidence of malperfusion, through open surgical repair.

Recruitment information / eligibility

• Status: Recruiting
• Enrollment: 93
• Est. completion date: March 2028
• Est. primary completion date: March 2024
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years to 80 Years

Eligibility

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

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Primary Endpoint to Assess Incidence of Major Adverse Events	Patients experiencing at least one of the following MAEs: All-cause mortality (ACM); New disabling stroke; New onset renal failure requiring dialysis; Myocardial infarction (MI)	Through 30 days
Primary	Primary Endpoint to Assess Change in Maximal True Lumen (TL) diameter	Patients with clinically meaningful (= 6.0 mm) true lumen expansion (at 1-Year), as defined by: Change in maximal true lumen (TL) diameter in the aortic arch at Zone 3 (2 cm distal to the origin of the left subclavian artery) from pre-operative computed tomography angiogram (CTA) measurements on admission to 1-year CTA measurements without need for device-related aortic reintervention.
