Primary Outcome Measures:
  • Composite of survival with improvement in Six Minute Hallway Walk Test distance from baseline of ≥ 75m. [ Time Frame: 12 months ]

Secondary Outcome Measures:
  • Risk stratified subgroup analysis of the primary endpoint and temporal analysis of primary endpoint. [ Time Frame: 6, 12, 18, and 24 months ]
  • Accuracy of prognostic survival risk models including Seattle Heart Failure Model (SHFM) and HeartMate II Risk Score (HMRS) [ Time Frame: Baseline and 6, 12, 18 and 24 months ]
  • Actuarial survival and survival free of stroke: a) intent-to-treat; and b) as treated. [ Time Frame: 24 months ]
  • Survival in LVAD group free of pump replacement. [ Time Frame: 24 months ]
  • Quality of Life using the EQ-5D-5L Health Utility Index. [ Time Frame: Baseline and 6, 12, 18 and 24 months ]
  • Depression using Patient Health Questionnaire-9 (PHQ-9). [ Time Frame: Baseline and 6, 12, 18 and 24 months ]
  • Questionnaire on patient decisions related to LVAD therapy versus optimal medical management. [ Time Frame: Baseline and 6, 12, 18 and 24 months ]
  • Functional status using 6MWT distance and NYHA Classification [ Time Frame: Baseline and 6, 12, 18 and 24 months ]
  • Incidence of adverse events, rehospitalizations, days alive and not hospitalized. [ Time Frame: 3, 6, 9, 12, 15, 18, 21 and 24 months ]

Groups/Cohorts Assigned Interventions
HM II (HeartMate II LVAD)
Subjects who elect to, and receive HM II LVAD therapy at baseline
Device: HM II (HeartMate II LVAD)
The HM II pump contains a single moving component, the rotor. The pump is implanted just below the left hemidiaphragm with the inflow attached to the apex of the left ventricle and the outflow graft anastomosed to the ascending aorta. Blood is pumped continuously throughout the cardiac cycle from the left ventricle to the aorta.
Other Name: Left Ventricular Assist Device
OMM (Optimal Medical Management)
Subjects who elect to remain on optimal medical management
Drug: OMM (Optimal Medical Management)
Optimal medical management per established heart failure guidelines for this subject population including ACE inhibitors, beta blockers and aldosterone antagonists 45 out of the last 60 days or an inability to tolerate neurohormonal antagonists.
Other Name: Medical Management

Detailed Description:

The HeartMate II (HM II) LVAD is approved by the U.S. Food and Drug Administration (FDA) for use in destination therapy (DT) patients with New York Heart Association (NYHA) Class IIIB/IV symptoms.

The ROADMAP trial is a prospective, multi-center, non-randomized, controlled, observational study that is designed to evaluate the effectiveness of HM II LVAD support versus optimal medical management (OMM) in ambulatory NYHA Class IIIB/IV heart failure patients who are not dependent on intravenous inotropic support and who meet the FDA approved indications for HM II LVAD destination therapy. Subjects will be enrolled in one of two cohorts: OMM or LVAD. Together with the investigator, the subjects will decide which cohort to enter into at their baseline visit. This study will include experienced HM II LVAD implant centers as well as community centers that care for a large volume of heart failure patients. Study patients will be followed for up to 24 months post enrollment for survival, quality of life and functional status.


Ages Eligible for Study:   18 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
HM II implanting centers and community/referral heart failure clinics
