Key inclusion & exclusion criteria

Inclusion criteria:
Inclusion criteria at screening:
- Male or female adult aged 18 years or more,
- Outpatient,
- Patient with persistent AF for more than 72 hours (documented by an ECG taken within the last 72 hours) for whom cardioversion, anti-arrhythmic treatment and anticoagulation treatment are indicated in the opinion of the Investigator (Note: patient may already be on anticoagulation treatment),
- Naive of amiodarone treatment in the last three months prior to screening,
- QTcB < 500 ms on 12-lead ECG,
- Patient with at least one cardiovascular risk factor (i.e. age > 70, hypertension, diabetes, prior cerebrovascular disease, left atrial diameter = 50 mm or left ventricular ejection fraction [LVEF] < 40%),
- Signed written informed consent.


Inclusion Criteria: to be checked at randomization
- Outpatient (only hospitalization of 48h for a planned cardio-version will be allowed),
- Patient in sinus rhythm (Note: if cardioversion is performed on Day 1 prior to randomization, then the patient must be in sinus rhythm for at least one hour before randomization),
- Patient under effective oral anticoagulation according to ACC/AHA/ESC 2006 guidelines.
- QTcB < 500 ms and PR < 280 ms on 12-lead ECG,
- Patient having received 28 days ± 2 days of amiodarone.

Exclusion criteria:
•Exclusion criteria at screening:
- Contraindication to oral anticoagulation,
- Any documented AF episode motivating inclusion in the study after an acute condition known to cause AF (e.g. alcohol intake, thyrotoxicosis, acute infection, pericarditis, pulmonary embolism, cardiac surgery),
- Patient with permanent AF in which cardioversion has failed,
- Patient with paroxysmal AF in whom cardioversion is not indicated,
- Bradycardia < 50 beats per minute (bpm) at rest on the 12-lead ECG,
- Clinically overt congestive heart failure:
o with New York Heart Association (NYHA) class III and IV heart failure,
o or NYHA class II with a recent decompensation requiring hospitalization or referral to a specialized heart failure clinic,
o as well any patient in unstable hemodynamic conditions.
- Women of childbearing potential without adequate birth control (e.g. oral contraception or intra-uterine device [IUD]) or not menopaused, not sterile or not hysterectomized,
- Pregnant women,
- Breastfeeding women,
- Previous (2 preceding months) or current participation in another clinical trial with an investigational drug or with an investigational device,
- Clinically relevant hematologic, underlying hepatobiliary disease, gastrointestinal, pulmonary, endocrinologic, psychiatric, neurological or dermatological disease,
- Severe hepatic impairment,
- Severe renal impairment (creatinine clearance < 30 mL/min),
- Serum potassium <3.5 millimol/liter (mmol/L) (in patients with hypokalemia, potassium deficiency must be corrected before randomization) or > 5.5 mmol/l,
- Magnesemia < 0.8 mml/l (in patient with hypo-magnesemia, magnesium deficiency must be corrected before randomization),
- Unstable angina pectoris (ischemic symptoms during the last 7 days) or recent myocardial infarction (MI) (< 6 weeks),
- First degree family history of sudden cardiac death below age 50 years in the absence of coronary heart disease,
- Second- or third- degree Atrio-Ventricular block or sick sinus syndrome (except when used in conjunction with a functioning pacemaker),
- Ongoing potentially severe symptoms when in AF such as angina pectoris, transient ischemic attacks, stroke, syncope, as judged by the investigator,
- Wolff-Parkinson-White Syndrome,
- Previous ablation for atrial fibrillation or any planned ablation in the next following 2 months.

Exclusion criteria to be checked at randomization

o as well any patients in unstable hemodynamic conditions.

- Serum potassium <3.5 millimol/liter (mmol/L) (in patients with hypokalemia, potassium deficiency must have been corrected before randomization) or > 5.5 mmol/l,

Primary Outcome(s)

Main Objective: The primary objective of the study is to evaluate the rate of AF recurrences one month after randomization according to different timings of initiation of dronedarone.

Primary end point(s): The primary efficacy criterion is the rate of AF recurrences one month after randomization according to different timings of initiation of dronedarone.

Secondary Objective: The secondary efficacy objective is to evaluate the rate of AF recurrences two months after randomization.
To assess the safety of the change from amiodarone to dronedarone
To assess dronedarone safety
