NCT04545112

Brief Summary

A prospective, single arm, non-randomized FIH feasibility study to evaluate the preliminary safety and performance of the XABG technology in patients with multi-vessel atherosclerotic coronary artery disease, scheduled by the local Heart Team to undergo elective coronary artery bypass (CABG) surgery.

Conditions

Outcome Measures

Primary Outcomes (2)

  • Procedural success during the first 30 days

    XABG technology performs as intended with successful proximal and distal anastomoses and graft patency at the conclusion of the procedure and at 30 days. Patency is defined as a diameter stenosis less than 50%

    30 days

  • Freedom from device related Serious Adverse Events (SAEs)

    30 days

Secondary Outcomes (5)

  • Intimal hyperplasia area

    12 months

  • Graft patency

    30 days, 6 months, 12 months

  • Lumen diameter uniformity

    30 days, 6 months, 12 months

  • Freedom from Major Adverse Cardiac and Cerebrovascular Events (MACCE)

    30 days, 6 months, 12 months, and yearly until 5 years

  • Freedom from vein harvesting related wound infection, non-infective wound healing disturbances, and leg pain

    30 days and 6 months

Study Arms (1)

XABG

EXPERIMENTAL
Device: CABG

Interventions

CABGDEVICE

Elective, coronary artery bypass (CABG) surgery. Each study subject will receive an left internal mammary artery (LIMA) conduit to the left anterior descending (LAD) coronary artery. Patients with uncompromised saphenous veins will receive a SVG to the LCX or RCA and the XABG to the remaining territory. Patients with compromised arterial and/or saphenous veins, (i.e., "no-vein" patients), will receive one XABG to the LCX or RCA to achieve incomplete revascularization.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • All gender, 18 years of age or older with a minimum life expectancy of 2 years.
  • Elective multi-vessel atherosclerotic CAD patients, selected and accepted by the local Heart Team and confirmed by the Screening Committee for CABG surgery.
  • LIMA bypass graft to LAD coronary artery indicated and feasible.
  • XABG target vessel(s) with proximal occlusion and/or critical stenosis. and with a diameter of ≥ 2 mm and sufficient distal run-off (thrombolysis in myocardial infarction risk (TIMI)-Score ≥ 2).
  • Patient has been informed of the nature of the study, agrees to its provisions, and has provided written informed consent.
  • Patient has been informed and agrees to pre- and post-procedure follow-up, including follow-up CT scan and coronary angiogram.
  • Patient is suitable for percutaneous coronary intervention (PCI) procedures in case of required emergent procedures at discretion of the local Heart Team.

You may not qualify if:

  • Total arterial bypass grafting indicated and feasible
  • Any previous open-heart surgery or surgical/transcatheter procedure that could compromise imaging follow up.
  • History of cardiac resynchronization therapy (CRT) or implantable cardioverter defibrillator (ICD) implantation
  • Concomitant cardiac surgery (e.g. valve treatment, ablation).
  • Myocardial infarction (MI) within 21 days or cerebral vascular accident (CVA) within 90 days prior to the CABG procedure
  • Left ventricular ejection fraction ≤ 35%.
  • Severe kidney disease, renal dysfunction (Cr\> 2.0mg/dL) or Glomerular Filtration Rate (GFR) \< 50mL/min or active dialysis patients.
  • Moderate to severe chronic obstructive pulmonary disease (COPD) with a forced expiratory volume (FEV) \<1.5 lit/sec.
  • Endocarditis, pericarditis or any other active systemic infection that would interfere with subject safety.
  • Active bleeding disorder and/or any coagulopathy or thromboembolic disease or other indication requiring anticoagulation
  • Known Heparin Induced Thrombocytopenia (HIT)
  • Abnormal blood values (e.g. leukopenia, anemia or thrombocytopenia) that could influence graft hemostasis or patient recovery.
  • Use of immunosuppressive therapy or medication or active clinically inflammatory/autoimmune disease or immunodeficiency that likely interferes with restorative therapies
  • Known and non-treatable allergies to study device (Nitinol) or agents/medication, such as contrast agents, antiplatelet therapy, beta-blocker, statins required for study assessment or optimal post-CABG medical treatment (hospital SOC).
  • Need for emergency surgery for any reason and/or intervention/surgery prior to and within 12 months after the CABG surgery that requires antiplatelet therapy discontinuation.
  • +9 more criteria
