  Purpose

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.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
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
    • Pregnant women
    • Nursing mothers
