摘要: The standard treatment for stroke risk patients with non-valvular atrial fibrillation (NVAF) is the use of oral anticoagulants (OACs). However, a substantial number have relative or absolute contraindications to OACs due concerns major bleeding and other adverse effects while using anticoagulation therapy. Recently, occurrences exclusion left appendage (LAA) in contraindication therapy are widely expanding worldwide, causing contentious discussions. LAA commonest place thrombus formation; therefore, concept occlusion reducing embolic events NVAF very important. current understanding available evidence on efficacy safety closure (LAAC) Watchman device contraindicated aim this focused review. After reviewing significant body literature, world experience no randomized trials, it suggested that implantation effective safe high-risk
