Brief Summary:

To compare heart function, symptoms, exercise capacity and quality of life in patients with Congestive Heart Failure (CHF) and Atrial Fibrillation (AF)before and after catheter ablation.

Hypothesis: Restoration and maintenance of sinus rhythm by catheter ablation, without the use of antiarrhythmic drugs, in AF and CHF improves heart failure status.

Group/Cohort Intervention/treatment
Optimal Medical therapy
Subjects with Class I,IIor III congestive heart failure on optimal medical therapy. Planned catheter ablation for paroxysmal or persistent atrial fibrillation. Paroxysmal AF defined as recurrent AF(2 or more episodes in one month) that terminate within seven days. Persistent AF defined as sustained beyond seven days, or lasting less than seven days but requiring pharmacologic or electrical cardioversion.
Procedure: Pulmonary Vein Isolation (PVI)
Subjects with clinical indication for PVI, either paroxysmal or persistent AF failing medical management with rate or rhythm control medications.
Other Name: Catheter Ablation

Primary Outcome Measures :
  1. Improvement in LVESV by 15% or more from baseline at 6 months [ Time Frame: 6 months ]

Secondary Outcome Measures :
  1. Remodeling as demonstrated by atrial & ventricular dimensions on echocardiogram [ Time Frame: 6 months ]
  2. NYHA Class [ Time Frame: 6 months ]
  3. Quality of Life [ Time Frame: 6 months ]
  4. Six minute hall walk test [ Time Frame: 6 months ]
  5. Hospitalization for HF [ Time Frame: one year ]
    Composite hospitalization for HF,thromboembolic complications, major bleeding or all cause mortality

  6. Absence of Atrial fibrillation [ Time Frame: one year ]
