[Antithrombotic approaches in patients undergoing left atrial appendage occlusion: current evidence and future...

Area of Science:

• Cardiology
• Interventional Cardiology
• Thrombosis Management

Background:

• Percutaneous left atrial appendage occlusion (LAAO) is an alternative stroke prevention method for patients with atrial fibrillation (AF) and contraindications to oral anticoagulants.
• Post-LAAO, antithrombotic therapy is recommended to promote device endothelialization and prevent thrombosis.
• Current antithrombotic strategies lack robust evidence and are often empirical.

Purpose of the Study:

• To review current evidence and guidelines on antithrombotic therapy following LAAO.
• To propose individualized antithrombotic strategies based on patient-specific risks.

Main Methods:

• Literature review of existing studies on LAAO and antithrombotic therapy.
• Analysis of recommendations from major scientific societies.
• Synthesis of evidence to guide individualized treatment approaches.

Main Results:

• Limited high-quality evidence exists for optimal post-LAAO antithrombotic regimens.
• Device thrombosis and bleeding are key complications to manage.
• Individualized strategies considering hemorrhagic and thrombotic risk are suggested.

Conclusions:

• Antithrombotic therapy after LAAO requires careful consideration of individual patient factors.
• Personalized approaches may optimize safety and efficacy in stroke prevention.
• Further research is needed to establish definitive evidence-based guidelines.
