[Left atrial appendage closure : Current data and future developments]

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Devices

Background:

• Catheter-based left atrial appendage closure (LAAC) is an established stroke prevention strategy for atrial fibrillation patients at high risk of stroke and bleeding.
• Recent advancements in LAAC devices, implantation techniques, and operator experience have significantly improved procedural safety.
• The effectiveness of LAAC is supported by data demonstrating stroke risk reduction, potentially in conjunction with anticoagulation.

Purpose of the Study:

• To review current potential indications for LAAC procedures.
• To discuss ongoing randomized clinical trials evaluating LAAC in new patient populations and settings.
• To summarize advances in device development, implantation planning, and techniques, and explore future directions in LAAC treatment.

Main Methods:

• Review of current literature and clinical practice data on LAAC.
• Analysis of ongoing randomized clinical trials investigating novel applications of LAAC.
• Discussion of technological advancements and procedural innovations in LAAC.

Main Results:

• LAAC demonstrates an improving safety profile and expanding indications beyond high-risk patients.
• Novel indications include patients with lower bleeding risk, post-pulmonary vein ablation, and post-left atrial appendage electrical isolation.
• Active clinical studies are crucial for defining the optimal future use of LAAC.

Conclusions:

• LAAC is a evolving treatment option for stroke prevention in atrial fibrillation.
• Continued research and technological development are essential for expanding and refining LAAC applications.
• LAAC holds significant promise for optimizing stroke risk management in diverse patient groups.
