Condition atrial fibrillation
Treatment no amiodarone
Sponsor Inova Health Care Services
Start date January 2011
End date January 2015
Trial size 186 participants
Trial identifier NCT01416935, AAM


The purpose of this study is to determine whether anti arrhythmic medication, specifically Amiodarone, is required during the first three months post surgical ablation.

Hypothesis: Amiodarone will not be required during the first three months as verified by no increase in rehospitalizations for recurrent Atrial Fibrillation, and report of sinus rhythm at surgical follow up (approximately 3 weeks from date of surgery), 6 weeks and 12 weeks to include patients' first follow up with cardiologist at approximately 3 months post surgery.

Study Design

Allocation randomized
Endpoint classification safety/efficacy study
Intervention model parallel assignment
Masking open label
Primary purpose treatment
(Active Comparator)
Patient will be randomized not to receive to Amiodarone post Cox-Maze procedure unless indicated.
no amiodarone
This is a randomized study whereby patients who would routinely/usually be scheduled to receive Amiodarone as their anti-arrhythmic medication post surgical ablation will be randomly assigned to receive Amiodarone or no Amiodarone, but all other medications would remain as prescribed for patients following surgical ablation which will include beta blockade therapy unless contraindicated which is an American Heart Associated and Heart Rhythm Society recognized treatment.
(No Intervention)
Patients randomized to receive Amiodarone post Cox-Maze procedure which is our current standard of care.

Primary Outcomes

Change in Status of Rhythm Between Baseline and Follow-Up - Recurrence of Atrial Fibrillation
time frame: 3, 6, 12 weeks and 6 months post-procedure

Secondary Outcomes

Major Adverse Event Rate
time frame: 30 days post-procedure
