Inclusion Criteria

Any patient with atrial fibrillation requiring ablation
-able to achieve and maintain stable sinus rhythm during the mapping procedure
-be on therapeutic level of anticoagulation as determined by the physician

Exclusion Criteria

-Patients with left atrial thrombus or heavy echo contrast on trans-esophageal echo (TEE) prior to the procedure as per physician discretion and standard of care
-Chronic atrial fibrillation
- Inadequate anticoagulation as defined in the inclusion criteria.
-Significant underlying pulmonary disease

Primary Outcome Measures

Name	Time	Method
Pulmonary vein atrum isolation: disappearance of all local potentials in the areas of the pulmonary vein antrum defined by early activation in sinus rhythm and during coronary sinus (CS) pacing and by the presence of fractionated potentials. This will be assessed using a circular mapping catheter.[baseline, 3 months, 6 months and 12 months post procedure.]

Secondary Outcome Measures

Name	Time	Method
Flouroscopy duration measured by the timer on the flouroscopy machine[at completion of procedure]
