• •3. Known presence of cardiac thrombus
• •4. Left atrial diameter (LAD) ≥ 5.5 cm (anteroposterior diameter) within 180 days prior to the index procedure
• •5. Left ventricular ejection fraction (LVEF) \< 35% as assessed with echocardiography or computerized tomography (CT) within 180 days prior to the index procedure
• •6. New York Heart Association (NYHA) class III or IV heart failure
• •7. Body mass index \> 40 kg/m2
• •8. Pregnant or nursing
• •9. Patients who have had a ventriculotomy or atriotomy within the preceding 28 days of procedure
• •10. Myocardial infarction (MI), acute coronary syndrome, percutaneous coronary intervention (PCI), or valve or coronary bypass grafting surgery within preceding 90 days
• •11. Stroke or TIA (transient ischemic attack) within the last 90 days
• •12. Heart disease in which corrective surgery is anticipated within 180 days after procedure
• •13. History of blood clotting or bleeding abnormalities including thrombocytosis, thrombocytopenia, bleeding diathesis, or suspected anti-coagulant state
• •14. Contraindication to long term anti-thromboembolic therapy
• •15. Patient unable to receive heparin or an acceptable alternative to achieve adequate anticoagulation
• •16. Known sensitivity to contrast media (if needed during the procedure) that cannot be controlled with pre-medication
• •17. Previous left atrial surgical or left atrial catheter ablation procedure (including left atrial appendage (LAA) closure device)
• •18. Plans to have an LAA closure device implanted during the follow-up period
• •19. Presence of any condition that precludes appropriate vascular access
• •20. Severe mitral regurgitation (regurgitant volume ≥ 60 mL/beat, regurgitant fraction ≥ 50%, and/or effective regurgitant orifice area ≥ 0.40cm2).
• •21. Previous tricuspid or mitral valve replacement or repair
• •22. Patients with prosthetic valves
• •23. Patients with a myxoma
• •24. Patients with an interatrial baffle or patch as the transseptal puncture could persist and produce an iatrogenic atrial shunt

• •28. Active systemic infection
• •29. Renal failure requiring dialysis
• •30. Severe pulmonary disease (e.g., restrictive pulmonary disease, constrictive or chronic obstructive pulmonary disease) or any other disease or malfunction of the lungs or respiratory system that produces severe chronic symptoms
• •31. Presence of an implantable therapeutic cardiac device including permanent pacemaker, biventricular pacemaker, or any type of implantable cardiac defibrillator (with or without biventricular pacing function) or planned implant of such a device for any time during the follow-up period. Presence of an implantable loop recorder is acceptable as long as it is removed prior to insertion of the investigational device.
• •32. Patient is currently participating in another clinical trial or has participated in a clinical trial within 30 days prior to screening that may interfere with this clinical trial without pre-approval from this study Sponsor
• •33. Unlikely to survive the protocol follow up period of 12 months
• •34. Presence of other medical, anatomic, comorbid, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements, or impact the scientific soundness of the clinical investigation results.
• •35. Individuals without legal authority
• •36. Individuals unable to read or write
