Brief Summary:
This study is a multi-center, randomized, unblinded, clinical trial. The objective is to determine if catheter-based atrial fibrillation (AF) ablation is superior to medical treatment in patients with impaired left ventricular (LV) function who have been diagnosed with symptomatic AF within the past 12 months.

Condition or disease Intervention/treatment Phase
Congestive Heart Failure Left Ventricular Failure Atrial Fibrillation Device: Catheter Ablation Drug: FDA approved anti arrhythmic drug Phase 4

Detailed Description:
The purpose of the trial is to compare two different approved treatments for recently diagnosed AF: anti-arrhythmic medications and AF ablation. The study will be conducted to determine if one treatment is more effective than the other for patients with AF and heart failure. About 220 subjects with newly diagnosed AF from hospitals in the United States will take part in this study. Subjects will be randomized in a 1:1 fashion to either AF catheter ablation or anti-arrhythmic medication for treatment of AF. Both therapies are considered Standard of Care.

Arm Intervention/treatment
Active Comparator: AF catheter Ablation
Pulmonary Vein Isolation catheter ablation for treatment of AF. AF catheter ablation is an FDA approved treatment for AF
Device: Catheter Ablation
During ablation, a doctor inserts a catheter through blood vessels into the heart. The doctor looks at the electrical activity of the heart. The catheter is used to determine which areas of the heart are causing AF. After the area is identified, the doctor uses a special machine delivers energy through the catheter to tiny areas of the heart muscle that is causing AF. This energy causes a scar in the tissue which "disconnects" the pathway of the AF.
Other Name: Pulmonary Vein Isolation

Active Comparator: FDA approved anti arrhythmic drug
FDA approved anti arrhythmic drug for the treatment of AF will be based on treating physicians' preference in accordance to guidelines.
Drug: FDA approved anti arrhythmic drug
Anti arrhythmic drug medical treatment will be based on treating physicians discretion following standard clinical guidelines

Primary Outcome Measures :
  1. First hospitalization for heart failure, recurrence of AF or Direct Current cardioversion [ Time Frame: 12 months ]
    Time measured in days to first hospitalization for heart failure, recurrence of AF or Direct Current cardioversion after the treatment period (first 3 months post enrollment or post procedure during which repeat ablation can be performed and titration of AADs can be performed).

Secondary Outcome Measures :
  1. Total number of cardiovascular hospitalization [ Time Frame: 15 months ]
    total number of cardiovascular hospitalization measured by hospitalization admissions

  2. Time to recurrence if AF lasting longer than 30 seconds [ Time Frame: 15 months ]
    time measured in days to recurrence of AF lasting longer than 30 seconds

  3. Distance walked in a 6-mile walk test [ Time Frame: 3 months through 15 months ]
    change in distance walked in 6 mile walk test

  4. Change in the Rand 36-Item Health Survey [ Time Frame: 3 months through 15 months ]
    change in the Rand 36-Item Health Survey reflective of change in patient's quality of life

  5. Change in Ejection Fraction (EF) [ Time Frame: baseline through15 months ]
    Change in Ejection Fraction heart failure measurement (percentage)
