Brief Summary:
The objective of the study is to evaluate the safety and effectiveness of the HM3 LVAS by demonstrating non-inferiority to the HMII LVAS (HMII) when used for the treatment of advanced, refractory, left ventricular heart failure.

Condition or disease Intervention/treatment Phase
Advanced Refractory Left Ventricular Heart Failure Device: HeartMate 3 LVAS Device: HeartMate II LVAS Not Applicable

Detailed Description:
The HM3 LVAS is intended to provide hemodynamic support in patients with advanced, refractory left ventricular heart failure; either for short term support, such as a bridge to cardiac transplantation (BTT) or myocardial recovery, or as long term support, such as destination therapy (DT). The HM3 is intended for use inside or outside the hospital.

Primary Outcome Measures :
  1. Short Term Primary End Point [ Time Frame: The first 294 randomized Subjects will be followed for 6 months or to outcome (transplant, explant, or death), whichever occurs first. ]
    Survival at 6 months free of disabling stroke (Modified Rankin Score > 3) or reoperation to replace or remove a malfunctioning device

  2. Long Term Primary End Point [ Time Frame: The first 366 randomized Subjects will be followed for 24 months or to outcome (transplant, explant, or death), whichever occurs first. ]
    Survival at 2 years free of disabling stroke (Modified Rankin Score > 3) or reoperation to replace or remove a malfunctioning device


Secondary Outcome Measures :
  1. Powered Secondary End Point: Pump Replacement at Two Years [ Time Frame: As they occur up to 24 months or to Outcome, whichever occurs first ]
    In addition to powering the study on the primary endpoints for PMA approval, the study will pre-specify a powered secondary endpoint to evaluate incidence of pump replacements at 24 months. HeartMate II is the control.

  2. EuroQoL 5D-5L (EQ-5D-5L) Total Score [ Time Frame: Baseline to 24 months ]
    Quality of Life as measured by EuroQoL 5 Dimension-5 Level (EQ-5D-5L) total score. The EQ-5D-5L questionnaire has patients rate their quality of life across 5 categories of mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The scores from the 5 dimensions are summed for the total score which ranges from 5 to 25 with higher scores indicating more problems and a worse quality of life.

  3. EuroQol-5D-5L Visual Analogue Scale [ Time Frame: Baseline to 24 months ]
    Quality of life as measured by the visual analogue scale from the EuroQol-5D-5L questionnaire. The patient rates their current state of health with the visual analogue scale. The scale ranges from 0 to 100. Higher scores indicate a better quality of life.

  4. Kansas City Cardiomyopathy Questionnaire (KCCQ) Overall Summary Score [ Time Frame: Baseline to 24 months ]
    Quality of Life as measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ). Scores range from 0 to 100. Higher scores indicate better quality of life and fewer heart failure symptoms.

  5. Six Minute Walk Test [ Time Frame: Baseline to 24 months ]
    Functional status as measured by the Six Minute Walk Test. The Six Minute Walk Test measures the distance a patient is able to walk during 6 minutes without running or jogging.

  6. New York Heart Association (NYHA) Classification [ Time Frame: Baseline to 24 months ]
    Functional status as measured by NYHA classification. NYHA class categorizes patients by the severity of their heart failure symptoms. As the class increases, the degree of symptoms is more severe indicating worse functional status. Class I indicates no limitation of physical activity. Class II indicates slight limitation of physical activity. Class IIIA indicates marked limitation of physical activity where less than ordinary physical activity causes fatigue, palpitation, dyspnea, or angina pain. Class IIIB indicates marked limitation of physical activity where mild physical activity causes fatigue, palpitation, dyspnea, or angina pain. Class IV indicates inability to carry on any physical activity without discomfort.

  7. Rehospitalizations [ Time Frame: From initial discharge to two years post-implant ]
    Rate of all cause rehospitalization

  8. Adverse Event Rates [ Time Frame: Two years post-implant ]
    Events-per-patient-year (EPPY) for anticipated adverse events as defined in the study protocol
