Left Atrial Appendage: Anatomy and Imaging Landmarks Pertinent to Percutaneous Transcatheter Occlusion

Percutaneous left atrial appendage (LAA) closure represents a complementary option and effective treatment for patients at risk of thromboembolism, especially in patients for whom it may be difficult to achieve satisfactory anticoagulation control or where anticoagulation treatment is not possible or desirable.

Effective and safe transcatheter LAA occlusion requires a detailed knowledge of crucial anatomic landmarks and endocardial morphologic variants of the LAA and its neighbouring structures. Our aim in this article is to provide the basic anatomic information that is important for the interventional cardiologist to know when planning an LAA occlusion procedure. Josh LeRibeus Authentic Jersey
