Percutaneous left atrial appendage closure: beyond the classic indications

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Devices

Background:

• Percutaneous left atrial appendage closure (LAAC) is an established stroke prevention strategy for non-valvular atrial fibrillation (NVAF).
• Current guidelines recommend LAAC for NVAF patients with high thromboembolic risk and contraindications or high risk associated with oral anticoagulation (OAC).

Purpose of the Study:

• To explore the expanded clinical utility of LAAC beyond traditional indications.
• To discuss the potential benefits of LAAC in specific patient populations and clinical scenarios.

Main Methods:

• Literature review and discussion of existing clinical evidence.
• Analysis of LAAC application in various hemorrhagic diseases and specific patient groups.

Main Results:

• LAAC may be beneficial in patients with specific hemorrhagic diseases, including cerebral amyloid angiopathy, age-related macular degeneration, hereditary hemorrhagic telangiectasia, and Moyamoya disease.
• LAAC is also considered for patients post-left atrial appendage electrical isolation, with persistent LAA thrombus, in end-stage renal disease, and in those with anticipated poor OAC compliance.

Conclusions:

• The role of LAAC in stroke prevention for NVAF is expanding.
• LAAC presents a viable alternative in numerous clinical situations not currently covered by standard guidelines.
