Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

"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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will evaluate the changes of different types of biomarkers before and after successful percutaneous implantation of an LAA occlusion device.

Biomarker evaluation will focus on blood derived biomarkers including neurohormones, proteins, cytokines, microRNAs and metabolomics.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* 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

Exclusion Criteria

* 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
