The Watchman FLX – a new device for left atrial appendage occlusion – design, potential benefits and first clinical experience
نویسندگان
چکیده
Although convincing data showed that left atrial appendage (LAA) occlusion could be used as an alternative to oral anticoagulants, LAA occlusion has emerged as a common procedure for stroke prevention in patients with atrial fibrillation and absolute or relative contraindications for oral anticoagulation in many European centers, based on current recommendations of the European Society of Cardiology. The efficacy and safety of the current generation Watchman LAA Closure System was established in two large randomized clinical trials (PROTECT AF, PREVAIL [1, 2]) and several prospective registries (CAP, ASAP, EWOLUTION [3–5]).

Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...

To the Editor: We read with great interest the report by Whitlock et al, who have highlighted the fact that the left atrial appendage (LAA) occlusion is an effective concept for stroke-prevention in patients with atrial fibrillation. The data presented in this report demonstrate improving safety and efficacy data on LAA occlusion with a noninferiority and even superiority to warfarin treatment ...
