Zenith LAA Occlusion System
Recruiting now · Not applicable
Conditions studied: Atrial Fibrillation, Left Atrial Appendage, Stroke
In brief
Demonstrate the safety and performance of the Zenith LAA Occlusion System and procedure to occlude the Left Atrial Appendage (LAA) from the left atrium (LA) using a minimally invasive technique. Indication - LAA closure in patients with non-valvular atrial fibrillation, with an ostial diameter between 18 mm and 26 mm

- Documented diagnosis of non-valvular AF
- Clinical indication for LAA occlusion
- Willing and able to return to and comply with scheduled follow-up visits and testing, including medical treatment as required by the protocol.
- Willing and able to provide written informed consent
You may not qualify if…
- Within 30 days before the procedure date:
- Exhibited NYHA class III or IV heart failure symptoms
- Known bleeding disorders (such as bleeding diathesis, thrombocytopenia [platelet count <100 X 109/L], severe anaemia [haemoglobin of <8 g/dL], or INR >2 [spontaneous])

- Documented embolic stroke, TIA or suspected neurologic event
- Chronic renal insufficiency (eGFR ≤15mL/min per 1.73 m2 (CKD-EPI)) or end-stage renal disease
- Requires long-term oral anticoagulation therapy for a condition other than AF
- Diagnosed active local or systemic infection, septicaemia, active pericarditis, or fever of unknown origin
- Known acquired or inherited propensity for forming blood clots (e.g., malignancy and factor V Leiden mutation) established by prior objective testing
- Contraindication to the standard of care post-implantation antithrombotic medication regime (e.g., dual antiplatelet therapy (DAPT)/direct oral anticoagulant (DOAC)
- Rheumatic heart disease
- Implanted mechanical valve prosthesis
- Documented carotid disease, defined as greater than 70% stenosis without symptoms or greater than 50% stenosis with symptoms
- Body mass index greater than 40 kg/m2
- Patient is pregnant or breastfeeding or plans/desires to get pregnant within the next 12 months post-procedure
- Current or planned enrolment in an investigation or study of an investigational device or investigational drug that would interfere with this study and the required follow-up
- Mental impairment or other psychiatric conditions which may not allow the patient to understand the nature, significance, and scope of the study
- Any other criteria (including physical and mental health), medical illness, or comorbidity which would make the subject unsuitable to participate in this study as determined by the clinical site principal investigator
- Patients with known allergy or sensitivity to nitinol (nickel and titanium) or any of the other materials in the Zenith LAA Occlusion System Implant
- Life expectancy of less than 1 year
- Inability, unwillingness, or contraindication to undergo Trans-Oesophageal and/or Trans-Thoracic Echocardiogram (TOE/TTE) or Cardiac Computed Tomography Angiography (CCTA) imaging or any catheterisation procedures
- Any anatomical condition that precludes the patient from undergoing LAA occlusion with the AuriGen Zenith LAA Occlusion System implant procedure, as determined by the principal investigator
- Imaging Exclusion Criteria:
- Patients with a maximal ostial left atrial appendage diameter >25 mm or <17 mm by pre-procedural ECG-gated CT scan, to fit the Zenith LAA Occlusion System
