Thromboaspiration of left atrial clot during ablation of atrial fibrillation

Area of Science:

• Cardiology
• Electrophysiology
• Medical Devices

Background:

• Atrial fibrillation ablation procedures carry risks, including thromboembolic events.
• Left atrial thrombus formation can complicate cardiac interventions.

Observation:

• A case is presented where a left atrial thrombus was visualized attached to a circular catheter during an atrial fibrillation ablation.
• The thrombus was identified within the left atrium.

Findings:

• Successful management of the left atrial thrombus was achieved through thromboaspiration.
• A steerable sheath facilitated the thromboaspiration procedure.

Implications:

• This case highlights the importance of recognizing and managing intraprocedural thrombus.
• Steerable sheaths offer a viable option for treating left atrial thrombus during ablation.
• Effective thrombus management can prevent severe complications such as stroke.
