NCT05951101

Brief Summary

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

Outcome Measures

Primary Outcomes (2)

  • Procedural success

    Acute procedural success is defined as the delivery and release of the Zenith LAA Occlusion System in the target location (LAA) without any device or procedure related serious adverse events until the post-procedure discharge or 72 hours (whichever comes first)

    72 hours

  • Mechanical device closure

    Mechanical device closure - residual jet around the device ≤5 mm at 45 days by TOE

    45 days

Secondary Outcomes (7)

  • Device related thrombus

    45 days and 12 months

  • SAE

    through study completion, an average of 1 year

  • Stroke

    12 months

  • Thromboembolism

    12 months

  • Device closure

    6 months

  • +2 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥18 at the time of screening
  • 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 \[spontaneous\])
  • Within 90 days before the procedure date:
  • Documented history of myocardial infarction or unstable angina
  • 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
  • +14 more criteria
