Use of a cerebral protection device to facilitate pulmonary vein isolation in a patient with left atrial mass arising from the interatrial septum.

Sentinel cerebral embolic protection devices (CPDs) may limit periprocedural cerebrovascular events by preventing micro and macro-embolization to the brain, and has been used in many cardiology and radiology procedures. We hereby report the use of a Sentinel CPD to facilitate safe and effective atrial fibrillation ablation in a patient with a left atrial mass arising from the interatrial septum.
