• Absolute contraindication to anticoagulation
• Major trauma such as head trauma, or other active intracranial, or intraspinal disease within 14 days
• Morbidly obese (BMI >50 kg/m2) patient who by the judgement of the investigator is high risk for bleeding
• Presence of intracardiac lead in the right ventricle or right atrium placed within 6 months
• Cardiovascular or pulmonary surgery within last 7 days

• Simultaneous participation in another investigational study
• Patients with known coagulation disorders such as antiphospholipid, Protein C, and Protein S
• Presentation of PE with paradoxical emboli which may be diagnosed by concurrent stroke or concurrent arterialization
