  9. Presence of mechanical aortic valve prosthesis
  10. History of cardiac transplantation
  11. History of recurrent and/or unprovoked deep vein thrombosis or pulmonary embolism
  12. Clinically significant untreated coronary artery disease requiring revascularization
  13. Any percutaneous cardiovascular intervention, cardiovascular surgery, or carotid surgery within 30 days.

  15. Myocardial infarction within 30 days of the procedure
  16. Active bacterial endocarditis within 180 days of the procedure
  17. Inability to tolerate or a medical condition precluding treatment with anti-thrombotic therapy
  18. Leukopenia, anemia, thrombocytopenia, history of bleeding diathesis or coagulopathy, or hypercoagulable states
  19. Hospitalization for CHF or hemodynamic instability requiring inotropic support or intra-aortic balloon pump within 30 days.
  20. Irreversible, severe pulmonary hypertension
  21. Patients with renal insufficiency or receiving renal replacement therapy
  22. Liver disease or significantly abnormal liver function test results
  23. Refusal of blood products
  24. Female who is pregnant or lactating
