Thoratec Corporation MOMENTUM 3, Multi-center Study of MagLev Technology in Patients Undergoing MCS Therapy With HeartMate 3™ IDE Clinical Study Protocol

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.

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.

         2. Technical obstacles which pose an inordinately high surgical risk, in the judgment of the investigator

         3. Existence of ongoing mechanical circulatory support (MCS) other than IABP

         4. Positive pregnancy test if of childbearing potential

         5. Presence of mechanical aortic valve that will not be either converted to a bioprosthesis or oversewn at the time of LVAD implant

         9. History of confirmed, untreated AAA > 5 cm in diameter within 6 months of enrollment

         10. Presence of an active, uncontrolled infection

         11. Intolerance to anticoagulant or antiplatelet therapies or any other peri/post-operative therapy the investigator will require based upon the patients' health status

         12. Presence of any one of the following risk factors for indications of severe end organ dysfunction or failure:

             1. An INR ≥ 2.0 not due to anticoagulation therapy

             2. Total bilirubin > 43 umol/L (2.5 mg/dl), shock liver, or biopsy proven liver cirrhosis

             3. History of severe chronic obstructive pulmonary disease (COPD) defined by FEV1/FVC < 0.7, and FEV1 <50% predicted

             4. Fixed pulmonary hypertension with a most recent PVR ≥ 8 Wood units that is unresponsive to pharmacologic intervention

             5. History of stroke within 90 days prior to enrollment, or a history of cerebrovascular disease with significant (> 80%) uncorrected carotid stenosis

             6. Serum creatinine ≥ 221 umol/L (2.5 mg/dl) or the need for chronic renal replacement therapy

             7. Significant peripheral vascular disease (PVD) accompanied by rest pain or extremity ulceration

         13. Patient has moderate to severe aortic insufficiency without plans for correction during pump implant

         14. Pre albumin < 150 mg/L (15mg/dL) or Albumin < 30g/L (3 g/dL) (if only one available) ; pre albumin < 150 mg/L (15mg/dL) and Albumin < 30g/L (3 g/dL) (if both available)

         15. Planned Bi-VAD support prior to enrollment

         16. Patient has known hypo or hyper coagulable states such as disseminated intravascular coagulation and heparin induced thrombocytopenia

         17. Participation in any other clinical investigation that is likely to confound study results or affect the study

         18. Any condition other than HF that could limit survival to less than 24 months
