Abstract

Endocardial left atrial appendage (LAA) occluders with a covering disc encompass a wide range of devices that share the common feature of a distal anchoring "body" and proximal covering "disc" design. This unique design feature has potential advantages in certain complex LAA anatomies and challenging clinical scenarios. The current review article summarizes the different features of established and novel devices, preprocedural imaging updates, intraprocedural technical considerations, and postprocedural follow-up issues specific to this category of LAA occluders.

Keywords: Atrial fibrillation; Cardioembolic stroke; Non-pharmacological treatment; Oral anticoagulant therapy.
