Inclusion criteria: 1. Aged between 18 and 80 years 2. History of paroxysmal (1 or more episodes of AF a month in the last 12 months, each lasting more than 60 min but less than 7 days, with all episodes terminating spontaneously) or persistent (2 or more episodes of AF in the last 12 months , each lasting more than 7 days before being terminated medically) atrial fibrillation first diagnosed at least 6 months before enrollment 3. Intolerant of antiarrhythmic drugs or in whom 2 or more antiarrhythmic drug regimens had failed
Exclusion criteria
Exclusion criteria: 1. Permanent atrial fibrillation (atrial fibrillation was the sole rhythm for the last 12 months) 2. Atrial fibrillation secondary to a transient or correctable abnormality, including electrolyte imbalance, trauma, recent surgery, infection, toxic ingestion, and endocrinopathy 3.

Design outcomes
Primary
| Measure | Time frame |

Secondary
| Measure | Time frame |
|---|---|
| Cumulative survival, measured as whether a patient is alive at 144 months follow-up (+/- 3 months). | — |
