Anti-Arrhythmic Medication (Amiodarone) Post Surgical Ablation for Atrial Fibrillation - Is it Necessary?
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.

Inclusion Criteria:
- Subject is ≥ 18 years of age

fibrillation as classified by the HRS Guidelines 8 [0]
- Subject must be selected as a candidate to undergo the Cox- Maze procedure for
ablation of atrial fibrillation

- Subject would normally be prescribed Amiodarone as an anti arrhythmic medication post
surgical ablation

authorization
- Subject is able and willing to comply with all study requirements including attending
all follow-up visits as deemed necessary by personal physician (cardiologist)
- Subject has a life expectancy of at least one year
Exclusion Criteria:
- Subject has undergone previous attempts at surgical Maze procedure or other AF
operation, including surgical or catheter ablation Subject has an accessory pathways
disorder (e.g. Wolff-Parkinson-White syndrome)
- Subject is in Class IV NYHA
- Subject has had a documented MI within 6 weeks prior to study enrollment
- Subject needs emergent cardiac surgery (i.e. cardiogenic shock)
- Subject has known carotid artery stenosis greater than 80%
- Subject has a current diagnosis of active systemic infection
- Subject is pregnant, planning to become pregnant within 12-14 months, or lactating
- Subject requires preoperative intra-aortic balloon pump or intravenous inotropes
- Subject has renal failure requiring dialysis
- Subject is diagnosed with hepatic failure
- Subject is on anti-arrhythmic drug therapy for the treatment of a ventricular
arrhythmia
- Subject has a known connective tissue disorder
- Subject is incarcerated
- Subject has previous or current therapy that could compromise tissue integrity
including thoracic radiation, chemotherapy, long-term oral or injected steroids
- Subject is an intravenous drug and/or alcohol abuser
- Subject is participating in concomitant research studies of investigational products
( e.g. Appendage closure devices, atrial septal defect patches)
