Indication, Patient Selection, and Referral Pathways for Left Atrial Appendage Closure

Interv Cardiol Clin. 2018 Apr;7(2):169-183. doi: 10.1016/j.iccl.2017.12.003.

Abstract

Left atrial appendage closure (LAAC) has emerged as a viable option for stroke prevention, especially in those intolerant of or not suitable for long-term oral anticoagulation therapy. This article describes the clinical characteristics, indications, and a proposed referral system for potential LAAC patients. Patient selection remains a challenge because of the paradox between the available randomized data on this intervention and the actual patient population who may gain maximum benefit. Further investigations comparing different LAAC devices with each other and with novel oral anticoagulants are needed. Also, the optimal antithrombotic regimen post-procedure has yet to be determined.
