About

The purpose of this study is to evaluate and compare the effectiveness of the HeartMate II (HM II) Left Ventricular Assist Device (LVAD) support versus 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.

Full 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.

Enrollment: 200 patients
