Brief Summary

"Left Atrial Appendage Occlusion and Biomarker Evaluation" (LABEL) is a single-center, prospective and observational study evaluating changes of the expression of biomarkers in eligible patients before and after percutaneous implantation of a left atrial appendage (LAA) occlusion device at mid-term follow-up.

Outcome Measures

Primary Outcomes (1)

  • Biomarker levels before successful LAA occlusion device implantation

    24 hours before intervention

Secondary Outcomes (2)

  • Biomarker levels after successful LAA occlusion device implantation

    mid-term follow up at 6 months

  • Changes of biomarker expression before and after device implantation over mid-term follow-up, depending of complete, incomplete occlusion, imaging data (transesophageal echocardiography, computed tomography)

    mid-term follow up at 6 months

Sampling MethodNon-Probability Sample
Study Population

Patients suffering from non valvular atrial fibrillation with a contraindication for oral anticoagulation (i.e. bleeding) being eligible of percutaneous implantation of LAA occlusion devices.

You may qualify if:

  • non valvular atrial fibrillation, that makes anticoagulation to prevent embolic stroke from the LAA
  • contraindication for the therapy with oral anticoagulants:
  • refusal to take oral anticoagulation
  • HasBled-score more than 3
  • prior bleedings under oral anticoagulation

You may not qualify if:

  • under 18 years
  • severely reduced left atrial function
  • mechanical heart valve
  • pulmonary embolism
  • deep vein thrombosis
  • myocardial infarction within the last 3 months
  • electrical cardioversion within 30 days after potential occluder implantation
  • atrial septum defect or interventional/surgical occlusion of ASD
  • status after heart transplant
  • symptomatic carotid artery stenosis
  • transient ischemic attack (TIA) or stroke within last 30 days
  • intracerebral bleeding within the last 2 months
  • acute infection
  • existing or planned pregnancy
