Conditions

Arrhythmia, Atrial Fibrillation

Brief summary

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.

Detailed description

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.

Interventions

A percutaneously delivered dual-filter protection device, designed to capture and remove debris dislodged during transcatheter aortic valve replacement procedures.

DIAGNOSTIC_TESTMagnetic Resonance Imaging

Cerebral MRI will be performed without gadolinium contrast using a 3 Tesla scanner prior to and 1 to 7 days after catheter ablation

Inclusion criteria

* Men / women over the age of 18 years undergoing radiofrequency, pulsed field or cryo-balloon ablation for AF in accordance with the current AHA/ACC/HRS guideline for management of patients with atrial fibrillation. This includes patients with symptomatic paroxysmal, persistent or long-standing persistent AF not responsive to or intolerant of a Class I or III anti-arrhythmic drug or patients with symptomatic paroxysmal or persistent AF prior to the initiation of a Class I or Class III antiarrhythmic drug). The decision to perform catheter ablation for AF will be made by the treating provider and the patient in accordance with the guidelines noted above. (January et al. J Am Coll Cardiol vol. 64, No. 21, 2014, page e1) * Able to provide informed consent. * Patients should have acceptable aortic arch anatomy and vessel diameters without significant stenosis as assessed using pre-procedure CT angiogram.

Exclusion criteria

* Anatomy unsuitable for use of Sentinel device: * Right extremity vasculature not suitable due to compromised arterial blood flow. * Brachiocephalic, left carotid or aortic arch not suitable due to excessive tortuosity, significant ectasia, stenosis (\>70%), dissection or aneurysm. * Cerebrovascular accident or transient ischemic attack within six months * Carotid disease requiring treatment within six weeks * Unable or unwilling to provide informed consent. * Pregnant women * Known history of dementia. * Known hypersensitivity to nickel-titanium. * Presence of MRI non-compatible implanted devices including cardiac implantable electronic devices. * The presence of left atrial thrombus. All patients routinely undergo transesophageal echocardiogram prior to ablation and / or intra-cardiac echocardiogram at the beginning of the ablation procedure to rule out the presence of left atrial thrombus. * Patients with a reversible cause for AF such as hyperthyroidism.

Design outcomes

Primary

MeasureTime frameDescription
Incident of overt and covert CNS injury 7 days post AF ablation7 days post AF ablationIncidence of overt and covert CNS injury confirmed using physical examination and / or brain imaging during or within 7 days of the AF ablation
Incident of overt and covert CNS injury 90 days post AF ablation90 days post AF ablationIncidence of overt and covert CNS injury during or within 90 days of the AF ablation

Secondary

MeasureTime frameDescription
Change in neurocognitive function scoreBaseline, 90 daysMontreal cognitive assessment will administered at baseline and 90 days following ablation. Change in cognitive function score will be compared between the groups. The score ranges from 0 to 30 with higher score indicating better cognitive performance.
New cerebral infarctsday 1 to 7 after atrial fibrillation ablationTotal number of new cerebral infarcts in the protected territories detected on brain MRI after ablation in the Sentinel device group vs control group
