Purpose
Show Detailed Description
The primary objective of this study is to demonstrate how dronedarone (Multaq®) may aid in the slowing of progression of left atrial and ventricular fibrosis in patients with atrial fibrillation as assessed by late gadolinium enhanced magnetic resonance imaging.

Primary Outcome Measures:
- LA Fibrosis [ Time Frame: 1 year ] [ Designated as safety issue: No ]The change from baseline to twelve months post initiation of the study treatments in left atrial fibrosis burden as measured by percentage of LGE-MRI.
Secondary Outcome Measures:
- LA and LV Dimensional and Volumetric Measures [ Time Frame: 1 Year ] [ Designated as safety issue: No ]Left atrial and ventricular dimensional and volumetric measurements by MR, as markers of disease progression/regression in the two arms of the study.

Criteria
Inclusion Criteria:
- Patients age 18 and older
- Must carry a diagnosis of Paroxysmal Atrial Fibrillation for 1 months or longer prior to being enrolled.
- AAD: Multaq® (dronedarone) candidate
- Patients have given informed consent
Exclusion Criteria:
- Patients who are unavailable to continue follow-up at the University of Utah outpatient clinic.
- Patients weighing >200 lbs (MR image efficacy decreases due to density)
- Prior RF Ablation treatment for atrial fibrillation
- Severe renal failure manifested by a chronic GFR of < 30 mL/min, or acute renal failure regardless of the GFR, until the renal function has stabilized. (Gadolinium contraindication)
- Enrollment in any other investigational trial for anti-arrhythmic therapy
- Any health related Gadolinium/MRI contraindications: Pacemaker devices, etc.
- Pregnant women
- Individuals with cognitive impairments who are unable to give informed consent
Multaq® (dronedarone) contraindications:
- NYHA Class IV heart failure or NYHA Class II - III heart failure with a recent decompensation requiring hospitalization or referral to a specialized heart failure clinic
- Second- or third-degree atrioventricular (AV) block or sick sinus syndrome
- Bradycardia < 50 bpm
- Concomitant use of strong CYP 3A inhibitors, such as ketoconazole, itraconazole, voriconazole, cyclosporine, telithromycin, clarithromycin, nefazodone, and ritonavir
- Concomitant use of drugs or herbal products that prolong the QT interval and might increase the risk of Torsade de Pointes, such as phenothiazine anti-psychotics, tricyclic antidepressants, certain oral macrolide antibiotics, and Class I and III antiarrhythmics
- QTc Bazett interval ≥ 500 ms or PR interval > 280 ms
- Severe hepatic impairment
