Management of device embolisation during left atrial appendage closure

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Device Technology

Background:

• Percutaneous left atrial appendage closure (LAAC) is a key stroke prevention strategy for atrial fibrillation patients unsuitable for anticoagulation.
• While LAAC safety has improved, device embolization remains a severe complication (0.1% of cases).
• Effective and rapid management of embolized devices is crucial to reduce mortality.

Purpose of the Study:

• To summarize European consensus recommendations for managing device embolization after LAAC.
• To outline strategies for percutaneous retrieval based on anatomical location.
• To emphasize necessary equipment for successful device retrieval.

Main Methods:

• Review of European Left Atrial Appendage Closure Club (EU LAAC Club) consensus recommendations.
• Analysis of device embolization management based on anatomical location (aorta, left atrium, mitral apparatus, left ventricle).
• Discussion of percutaneous retrieval techniques and required equipment.

Main Results:

• Percutaneous recapture is preferred for aortic or left atrial embolization.
• Emergent surgery is indicated for mitral apparatus entanglement with hemodynamic compromise.
• Transfemoral or transseptal retrieval is an option for stable left ventricular embolization.

Conclusions:

• Management of LAAC device embolization requires a tailored approach based on anatomical location and patient hemodynamics.
• Availability of specific retrieval equipment (e.g., snares, grasping tools) is essential in cath labs performing LAAC.
• Adherence to consensus recommendations ensures optimal patient outcomes following device embolization.
