Percutaneous left atrial appendage closure for stroke prevention: current challenges and future perspectives

Area of Science:

• Cardiology
• Medical Devices
• Stroke Prevention

Background:

• Stroke is a leading cause of death and disability globally.
• Non-valvular atrial fibrillation increases stroke risk.
• Oral anticoagulation is standard but not always feasible.

Purpose of the Study:

• To review the current state of percutaneous left atrial appendage closure (LAAC).
• To identify challenges and unmet needs in LAAC.
• To provide an updated perspective on this stroke prevention strategy.

Main Methods:

• Review of current literature and clinical data on LAAC.
• Analysis of approved and investigational LAAC devices.
• Discussion of evidence, adverse events, and post-procedural therapy.

Main Results:

• LAAC is a developing field with multiple device options.
• Key challenges include limited high-quality evidence and late adverse events.
• Uncertainty exists regarding optimal post-procedural antithrombotic therapy.

Conclusions:

• Percutaneous LAAC is a significant alternative for stroke prevention in specific patient groups.
• Further research is needed to address current limitations and optimize patient outcomes.
• The field requires more robust evidence and standardized protocols.
