Non-valvular Paroxysmal, Persistent, or Permanent Atrial Fibrillation

LAA Anatomy Amenable to Treatment by Percutaneous Technique

Eligibility:

Brief Summary

Purpose To establish the safety and efficacy of the Coherex WaveCrest Left Atrial Appendage Occlusion System for left atrial appendage (LAA) closure during treatment of non-valvular atrial fibrillatio...

Detailed Description

Primary Safety Endpoint The primary safety endpoint is the incidence of major adverse events up to 45 days post-procedure. Major adverse events are defined as life-threatening incidents as determined ...

Eligibility Criteria

Inclusion

  • Candidates for this study must meet ALL of the following criteria
  • At least 18 years of age.
  • Diagnosis of paroxysmal, persistent, or permanent non-valvular atrial fibrillation.
  • Indicated for long-term anticoagulation therapy including patients on anticoagulants and patients with a contraindication to anticoagulation. The first 30 patients must have a contraindication to anticoagulation.
  • Eligible for cessation of anticoagulation therapy if the LAA is sealed (i.e., the patient has no other condition requiring anticoagulation therapy).
  • Calculated CHADS score ≥ 1.
  • Willingness to participate in the required follow-up visits and tests.
  • Willingness of patient or legal representative to provide written informed consent.
  • Female subjects of child-bearing potential must have a negative serum pregnancy test within 7 days prior to the index procedure, and must be willing to use reliable contraception methods for one year post-procedure.

Exclusion

  • Known contraindication and/or allergy to aspirin, clopidogrel, IV contrast, or nickel.
  • Extensive congenital cardiac anomalies, which can only be adequately repaired by cardiac surgery.
  • Stroke or transient ischemic attack (TIA), as diagnosed by a neurologist, within the past 30 days. Patients with a history of stroke or TIA will not be allowed to enroll until 30 days post stroke or TIA have been completed.
  • New York Heart Association Class IV Congestive Heart Failure, defined as patients with severe physical limitations and symptoms even while at rest.
  • Myocardial infarction within the past three months.
  • Sepsis within one month prior to implantation or any systemic infection that cannot be successfully treated prior to device placement.
  • Presence of an atrial septal defect, atrial septal repair, or atrial septal closure device.
  • Female subjects who may be pregnant or are planning on becoming pregnant in the next year.
  • Cardioversion or ablation procedure planned in conjunction with or within 30 days after placement of the Coherex WaveCrest Left Atrial Appendage Occlusion System.
  • Cardiac transplant or mechanical valve.
  • Symptomatic carotid artery disease.
  • Any medical disorder or psychiatric illness that would interfere with successful completion of the study as determined by the investigator.
  • Conditions other than atrial fibrillation requiring long-term warfarin therapy.
  • Resting heart rate \> 110 beats per minute (bpm).
  • A single episode of transient atrial fibrillation.
  • Thrombocytopenia (\<50,000 platelets/mm3), thrombocythemia (\>700,000 platelets/mm³), leucopenia (white blood cell count \< 3,000 cells/mm³), or anemia (hemoglobin concentration \< 10 gram per deciliter \[g/dl\]).
  • Currently participating in an investigational drug or another device trial that has not completed the primary endpoint or that clinically interferes with the current trial endpoints. (Trials requiring extended follow-up for products that were investigational, but have since become commercially available, are not considered investigational trials.)
  • Any condition that would reduce life expectancy to less than two years from the date of the index procedure.
  • Echocardiographic criteria for exclusion:
  • Left ventricular ejection fraction (LVEF) \< 30%.
  • Mitral valve stenosis \< 1.5 cm2 or any stenosis consistent with rheumatic valvular disease.
  • Pericardial effusion \> 5 mm pre-procedure.
  • Evidence of intracardiac thrombus visualized on TEE.
  • Presence of a patent foramen ovale (PFO) that demonstrates a large shunt and/or atrial septal aneurysm with \> 10 mm excursion.
  • Cardiac tumor.
