Device-Related Thrombus After Left Atrial Appendage Closure

Area of Science:

• Cardiology
• Medical Devices
• Thrombosis

Background:

• Left atrial appendage closure (LAAC) is an alternative to oral anticoagulants for atrial fibrillation (AF) patients.
• Concerns exist regarding late complications, particularly device-related thrombus (DRT), after LAAC.
• DRT is linked to an elevated stroke risk.

Purpose of the Study:

• To discuss the incidence, risk factors, and temporal patterns of DRT following LAAC.
• To explore potential management strategies for DRT.
• To address the specific challenges in managing DRT in patients with contraindications to oral anticoagulants.

Main Methods:

• Review of existing literature on LAAC and DRT.
• Analysis of incidence, risk factors, and timing of DRT.
• Discussion of management approaches and individualized treatment decisions.

Main Results:

• DRT is a recognized late complication of LAAC.
• Specific risk factors and time courses for DRT development are identified.
• Management strategies, especially for anticoagulation-contraindicated patients, are still under investigation.

Conclusions:

• LAAC is a viable option for AF, but DRT risk necessitates vigilance.
• Individualized, multidisciplinary assessment is crucial for managing DRT, particularly in high-risk patients.
• Further research is needed to optimize DRT management strategies.
