ReviewInterventional treatments for stroke prevention in atrial fibrillation with emphasis upon the WATCHMAN device.
Stroke is a leading cause of death and disability worldwide. Many strokes occur in patients with atrial fibrillation. Current guidelines recommend an antithrombotic regimen with warfarin to prevent thromboembolism in atrial fibrillation; however, a substantial number of patients are not eligible for this therapy. The exclusion of the left atrial appendage from circulation seems to be an alternative strategy for stroke prevention in atrial fibrillation. The review focuses on the different devices for stroke prevention in patients with atrial fibrillation. ⋯ For both devices, a reduction in the risk of stroke was documented, and device implantation was shown to be safe and feasible. Provided the ongoing trials show noninferiority to oral anticoagulation, another therapeutic option will become available to prevent ischemic strokes.
