1% Aspiration, 99% Perspiration: Acute Left Atrial Thrombus During Percutaneous Left Atrial Appendage Occlusion

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Devices

Background:

• Atrial fibrillation increases stroke risk due to potential clot formation in the left atrial appendage.
• Left atrial appendage occlusion (LAAO) devices are used to reduce this risk.
• Complications during LAAO device implantation, such as thrombus formation, require careful management.

Purpose of the Study:

• To describe a case of successful thrombus aspiration during LAAO device implantation.
• To highlight a technique for managing unexpected thrombus during the procedure.

Main Methods:

• A 71-year-old male patient with chronic atrial fibrillation underwent LAAO.
• A large thrombus was identified attached to the delivery system before device release.
• Continuous negative pressure was applied to aspirate the thrombus during device deployment.

Main Results:

• The thrombus was successfully aspirated using the described method.
• The LAAO device was deployed without further complications.
• The patient experienced no clinical sequelae following the procedure.

Conclusions:

• Thrombus aspiration is a feasible technique for managing intraprocedural thrombus during LAAO.
• This approach can ensure successful device implantation and patient safety.
• Careful monitoring and preparedness are crucial for interventional cardiology procedures.
