- Chronic obstructive pulmonary disease with detected pulmonary hypertension and/or any other evidence of significant lung disease.
- Contraindication for oral anticoagulation.
- Pregnant women or woman of childbearing potential with inadequate birth control.
- Women who are breastfeeding.
- Any significant congenital heart defect corrected or not corrected; however, patent foramen ovale is allowed.
- Thrombocytosis (platelet count > 600,000/μL) or thrombocytopenia (platelet count < 100,000/μL).
- Untreated or uncontrolled hyperthyroidism or hypothyroidism.
- Renal dysfunction with glomerular filtration rate < 60 mL/min.
- Unstable angina pectoris.
- Symptomatic carotid stenosis.
- Myxoma based on laboratory abnormalities.
- Sarcoidosis.
- Unwilling to unable to comply with the study procedure and follow-up schedule due to any disease condition.
- Legal incapacity or evidence that the patient cannot understand the purpose and risks of the study, including inability to comply fully with study procedures and follow-up.
- Employed by Medtronic, or the department of an investigator, or close-familial relative of an investigator.
- Enrolled or planning to participate in a potentially confounding drug or device trial during this study.
