Long-term outcomes of successful left atrial appendage occlusion with focus on stroke prevention: 10-year follow-up of a single-center registry.

Background: Percutaneous left atrial appendage occlusion (LAAO) is an alternative to anticoagulation in the prevention of stroke in patients with nonvalvular atrial fibrillation, especially in patients with a contraindication for oral anticoagulation therapy (OAT).

Objective: The study sought to obtain long-term patient outcomes after successful LAAO in everyday clinical practice.

Methods: In this single-center registry spanning over 10 years, data of all consecutive patients that underwent percutaneous LAAO were collected.

Percutaneous left atrial appendage occlusion in patients with a cardiac implantable electronic device.

Background: Left atrial appendage occlusion (LAAO) may be a viable option for stroke prevention in patients with non-valvular atrial fibrillation and a contraindication for oral anticoagulation. No evidence evaluating the safety of this procedure in patients with a cardiac implantable electronic device (CIED) exists. The aim of this study was to evaluate whether CIED function is affected by LAAO and to explore LAAO procedural characteristics and complications in patients with a CIED.

COMPARE LAAO: Rationale and design of the randomized controlled trial "COMPARing Effectiveness and safety of Left Atrial Appendage Occlusion to standard of care for atrial fibrillation patients at high stroke risk and ineligible to use oral anticoagulation therapy".

Background: Left atrial appendage occlusion (LAAO) provides an alternative to oral anticoagulation (OAC) for stroke prevention in patients with atrial fibrillation (AF). In patients with a long-term or permanent contraindication for OAC randomized controlled trial (RCT) data is lacking.

Study Objectives: To assess the efficacy and safety of LAAO in AF patients who are ineligible to use OAC.
