Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Pulmonary Vein Isolation (PVI)

Intervention Type PROCEDURE

Subjects with clinical indication for PVI, either paroxysmal or persistent AF failing medical management with rate or rhythm control medications.
