Brief summary
Atrial fibrillation (AF) is more common in patients with renal disease compared to the general population an risk increase to as much as 10 times in patients on hemodialysis (HD). Stroke is an important cause of morbidity, mortality and suffering for patients with end-stage chronic kidney disease (ESCKD) on hemodialysis.The risk of bleeding in these patients can be roughly 5-fold higher that without it. Current guidelines recommend the use of oral anticoagulants (AO) to prevent stroke or systemic thromboembolism in high-risk patients with AF. Left atrial appendage occlusion (LAAO) reduces the risk of bleeding while allows thromboembolic stroke prevention. The aim of the study is to assess the procedural safety on stroke and bleeding prevention of LAAC in patients with non-valvular atrial fibrillation (NVAF) and ESCKD on HD.
