Outcome Measures

Primary Outcomes (11)

  • Primary Safety Endpoint

Secondary Outcomes (3)

  • Percentage of atrial surface of device covered

    45 days - 3 months - 13months

  • Maximal Hypoattentuated Thickening on atrial surface of device

    45 days - 3 months - 13months

  • Percentage of device length coverage

    45 days - 3 months - 13months

Interventions

Eligibility Criteria

Age18 Years+
Sexall
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with paroxysmal, persistent, or permanent non-valvular AF and CHA2DS2-VASc Score of ≥2 that are scheduled to undergo to an elective Left Atrial Appendage Closure

You may qualify if:

  • Age\> 18
  • Written informed consent to participate in the study
  • Patients with paroxysmal, persistent, or permanent non-valvular AF and CHA2DS2-VASc Score of ≥2 that are planned for an elective LAA-closure
  • Anatomic characteristics allow placement of a CE marked device, dedicated for LAAC

You may not qualify if:

  • None. Considering the nature of the project, which is to prospectively collect information on all patients treated with LAAC in our center, we will only exclude patients unwilling to sign the informed consent.
