Intervention Details:
  • Device: Ventricular Assist Device System
    Ventricular Assist Device System


Primary Outcome Measures :
  1. Success at 12 months with the following definitions of success and failure [ Time Frame: Implant to 12 months ]

    Therapy will be considered a success if, at the end of 12 months in the study:

    1. The subject is alive; and
    2. The subject has not had a stroke of Modified Rankin Score ≥ 4; and
    3. The subject retains the originally implanted device, unless the device was removed due to heart recovery, or the patient is electively transplanted.

    Therapy will be considered a failure if, within the 12 months in the study:

    1. The subject dies; or
    2. The subject has a stroke of Modified Rankin Score ≥ 4; or
    3. The device malfunctions or fails, requiring exchange, explantation, or urgent transplantation.


Secondary Outcome Measures :
  1. Incidence of all adverse events per INTERMACS definition [ Time Frame: Implant to 12 months ]
  2. Incidence of all device malfunctions per INTERMACS definition [ Time Frame: Implant to 12 months ]
  3. Health Status improvement, as measured by KCCQ [ Time Frame: Implant to 12 months ]
  4. Health Status improvement, as measured by EuroQol EQ-5D-5L [ Time Frame: Implant to 12 months ]

Criteria

Inclusion Criteria:

  1. Must be ≥20 years of age at consent
  2. In judgment of body size, body surface area (BSA) and anatomy by Investigator, patient can be implanted MDT-1118 VAD.
  3. Patients with advanced heart failure symptoms (Class IIIB or IV) who are: (patient must meet one of the following)

    1. On optimal medical management, including dietary salt restriction and diuretics, for at least 45 out of the last 60 days and are failing to respond; or
    2. In Class III or Class IV heart failure for at least 14 days, and dependent on intra-aortic balloon pump (IABP) for 7 days and/or inotropes for at least 14 days
  4. Left ventricular ejection fraction ≤ 25%
  5. LVAD implant is intended as destination therapy
  6. Must be able to receive the MDT-1118 VAD
  7. Female patients of childbearing potential must agree to use adequate contraceptive precautions (defined as oral contraceptives, intrauterine devices, surgical contraceptives or a combination of condom and spermicide) for the duration of the study
  8. The patient has signed the informed consent form and advance directive
  9. The patient and the family understand that destination therapy is end-of-life medical care.

Exclusion Criteria:

  1. Patients with INTERMACS profile 1
  2. Existence of any ongoing mechanical circulatory support (MCS) other than an intra-aortic balloon pump (IABP)
  3. Prior cardiac transplant
  4. History of confirmed, untreated abdominal/ thoracic aortic aneurysm > 5 cm, or cardiac aneurysm or intraventricular septum rupture
  5. Severe calcification in thoracic aorta
  6. Cardiothoracic surgery within 14 days of implantation
  7. Acute myocardial infarction within 14 days of implant as diagnosed by ST or T wave changes on the ECG, diagnostic biomarkers, ongoing pain and hemodynamic abnormalities as described in the guidelines published in ACC/AHA 2007 Guidelines for the Management of Patients with Unstable Angina/Non-ST-Elevation Myocardial Infarction1
  8. Patients eligible for cardiac transplantation
  9. On ventilator support for > 72 hours within the four days immediately prior to implantation

  12. Patient seems difficult to control device by oneself due to cerebral disorder
  13. History of drug intoxication or alcohol dependence
  14. Uncorrected moderate to severe aortic insufficiency. Correction may include repair or bioprosthesis at the time of implant
  15. Severe right ventricular failure as defined by the anticipated need for right ventricular assist device (RVAD) support or extracorporeal membrane oxygenation (ECMO) at the time of screening or right atrial pressure > 20 mmHg on multiple inotropes or right ventricular ejection fraction (RVEF) <15% with clinical signs of severe right heart failure (e.g. Lower extremity edema, ascites or pleural effusions refractory to treatment with diuretics and two inotropic drugs)
  16. Active, uncontrolled infection diagnosed by a combination of clinical symptoms and laboratory testing, including but not limited to, continued positive cultures, elevated temperature and white blood cell (WBC) count, hypotension, tachycardia, generalized malaise despite appropriate antibiotic, antiviral or antifungal treatment

  27. Peripheral vascular disease with rest pain or ischemic ulcers of the extremities
  28. Pregnancy
  29. Patient unwilling or unable to comply with study requirements
  30. Technical obstacles, which pose an inordinately high surgical risk, in the judgment of the investigator
