Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A study evaluating the incidence of ischaemic lesions detected by brain MRI scan in subjects undergoing pulsed-field ablation for atrial fibrillation (VARIPULSE system).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

An observational study evaluating the incidence of ischaemic lesions on brain MRI performed after ablation of atrial fibrillation using the Varipulse catheter.

1. A baseline MRI scan will be carried out one day before the procedure.
2. A post-procedure MRI scan will be performed 24-36 hours after the procedure.
3. A follow-up MRI will be performed within 1 year after the ablation.

Paroxysmal and non-paroxysmal AF patients will be included. Regarding the extent of ablation lesions, pulmonary vein isolation (PVI) will be performed in paroxysmal AF, whereas PVI + left atrial posterior wall ablation will be performed in non-paroxysmal patients. All procedures will be performed under intracardiac echocardiography guidance.

The patients will undergo a neurocognitive evaluation:

1. One day before the procedure: Montreal Cognitive Assessment (The MoCA Test)
2. 24-36 hours after the procedure: The National Institutes of Health Stroke Scale (NIHSS)
3. Up to 1 year after the procedure the MoCA test.
