Long-Standing Persistant Atrial Fibrillation-Pulmonary Vein Isolation With or Without Ablation

Ablation at St. Georg Hospital for Long-Standing Persistent Atrial Fibrillation - Pulmonary Vein Isolation With or Without Ablation of Complex Fragmented Atrial Potentials

The chronic success rate, defined as freedom from any atrial tachyarrhythmias will increase from 35% to 60% by ablation of complex fragmented atrial electrograms potentials in addition to pulmonary vein isolation (PVI) as compared to PVI alone in patients with long-standing persistent AF.

Inclusion Criteria:

• long standing persistent atrial fibrillation > 6 months and < 5 years

Exclusion Criteria:

• renal failure
• left atrial size >55 mm
