If assigned to receive the device, the Sentinel® Cerebral Protection System will be placed in your heart at the beginning of your ablation procedure, and then removed along with any collected blood debris upon completion of your procedure. The study team will then call you 30 days after your procedure to assess any neurological events. Your final visit will be 90 days after your procedure to complete a second 30 minute session of cognitive testing.
The purpose of the study is to see if the Sentinel® Cerebral Protection System may prevent occurrence of stroke during an ablation procedure for atrial fibrillation (AF). The secondary purpose of this study is to study if cognitive function after AF ablation differs between those treated with the Sentinel cerebral protection device and those who do not receive the device.
