The primary safety objectives include the assessment of the frequency and occurrence of all major bleeding events post-operatively up to day 3-11. Finally, the secondary efficacy objective will include cumulative VTE events and assessment of the components of VTE while the secondary safety objective will include an assessment of the frequency of non-major bleeding events up to day 3-11 as well as all cause deaths, need for transfusion and other monitored adverse events till day 35.
