A Pilot Investigation Detecting Cryoablation Scar by 3D Late Gadolinium

This is a prospective trial investigating the effectiveness of a modified MRI preparatory
pulse sequence to improve pulmonary vein isolation visualization.


Inclusion Criteria:

- Men or non-pregnant women

- A diagnosis of symptomatic paroxysmal or recently persistent atrial fibrillation with
a documented successful cardioversion within 4 months of the procedure

- Documented treatment failure or intolerance of at least 1 anti-arrhythmic medication
used to control atrial fibrillation.

Exclusion Criteria:

- Contraindication to MRI, such as implanted incompatible metal prosthesis, or subject
size exceeds bore or table limits

- Allergy to gadolinium-based contrast agent

- Previous atrial fibrillation ablation

- Renal dysfunction (estimated GFR <60 mL/min/1.73m2) within 6 months

- Unwilling to provide informed consent for this protocol
