High-resolution MRI of Atrial Fibrillation Patients Prior to Focal Impulse and Rotor Modulation (FIRM) Ablation

High-resolution Contrast-Enhanced MRI of Atrial Fibrillation Patients Prior to FIRM Ablation

Who can join

Ages 18 and older · All sexes · Healthy volunteers welcome

Inclusion Criteria:

1. Patients with symptomatic paroxysmal or persistent atrial fibrillation undergoing clinically-indicated ablation procedure employing FIRM mapping with pre-operative MRI.
2. Subjects must be at least 18 years of age.

Exclusion Criteria:

1. LAA thrombus present on pre-procedure TEE
2. Unable to undergo MRI imaging
3. Unable to receive gadolinium contrast.

About the study

Patients undergoing FIRM guided ablation of atrial fibrillation will undergo high resolution MRI imaging to determine correlation of underlying anatomic fibrotic regions with FIRM targeted sites for ablation.
