[Left atrial appendage closure for stroke prevention in atrial fibrillation : An update]. Herz. 2020 May 15;: Authors: Zimmermann F, Landmesser U Abstract Atrial fibrillation (AF) is one of the most frequent causes of ischemic stroke. Without treatment the annual risk of ischemic stroke is on average approximately 5-6%/year in patients with atrial fibrillation, depending on the overall cardiovascular risk profile. Oral anticoagulation with new oral anticoagulants (NOAC) or vitamin K antagonists (VKA) is recommended for patients with AF and an elevated risk for stroke (CHA2DS2-VASc score ≥1); however, severe bleeding complications are potential reasons for discontinuation of this treatment. Overall, up to 30 % of the patients with AF remain without effective thromboembolism prophylaxis. Left atrial appendage (LAA) closure represents an alternative to pharmaceutical stroke prevention. Catheter-based and surgical LAA closure techniques are available. For catheter-based procedures with closure systems, high implantation success rates and relatively low periprocedural complication rates have been observed in recent registry studies. The reason for the restrained recommendation in the European guidelines is the as yet limited experience from large randomized studies. PMID: 32415343 [PubMed - as supplied by publisher]
