Summary

The POPULAR-LAAO registry is an open-label observational prospective registry to investigate hemostatic processes following left atrial appendage occlusion.

Detailed description

This is an open-label observational prospective registry. The aim is to develop a better understanding of coagulation, platelet reactivity and prothrombotic factors in the first months after left atrial appendage occlusion, as occurrence of device-related thrombus and optimal postprocedural management remain a challenge after LAAO. The study population will consist of patients with non-valvular atrial fibrillation (AF) at risk for cardio-embolic stroke scheduled for left atrial appendage occlusion. In these patients, blood samples for coagulation and platelet reactivity testing will be taken, which will be gathered prior to the procedure and 1 day, 14 days, 3 months and 6 months after the procedure. Data will be analyzed longitudinally and between groups based on patient characteristics.
