title: Implantation of bilateral carotid artery filters to allow safe removal of left atrial thrombus during ablation of atrial fibrillation.
abstract: Left atrial clot formation is a feared complication of catheter ablation for atrial fibrillation. We report a case of left atrial thrombus that formed around the circular mapping catheter before the delivery of RF. Successful retrieval of the clot was obtained by withdrawing the catheters while protecting the anterior cerebral circulation by positioning temporary carotid artery filters.
