Brief Summary
The primary purpose of this registry is to obtain real-world clinical experience of Paroxysmal (PAF) and Persistent (PsAF) Atrial Fibrillation ablation radiofrequency (RF) technologies. Data from the registry will be used to assess clinical outcomes, including procedural efficiency, safety, and long-term, effectiveness of catheter ablation with novel RF technologies in PAF and PsAF patients.

Study Arms (1)
Patients with atrial fibrillation
Subjects with symptomatic PAF or PsAF who, in the opinion of the investigator, are candidates for ablation for AF, age 18 years or older, and are able and willing to comply with all pre-, post-, and follow-up testing and requirements.
Interventions
Ablation RF technologies (e.g., THERMOCOOL SMARTTOUCH®, THERMOCOOL SMARTTOUCH® SF).
Eligibility Criteria
Study population consists of adults age 18 years or older with symptomatic Paroxysmal and Persistent Atrial Fibrillation who are candidates for ablation.
You may qualify if:
- Symptomatic Paroxysmal (AF episode terminate spontaneously within 7 days) or Persistent (AF sustained beyond 7 days) who, in the opinion of the investigator, are candidates for ablation for AF
- years of age or older
- De Novo ablation procedure unless it is a repeat for a patient whose index procedure is also in the registry
- Able and willing to participate in baseline and follow up evaluations for the full length of the registry
- Willing and able to provide informed consent, if applicable
You may not qualify if:
- Enrolled in an investigational drug or device clinical trial, or any trial that dictates the treatment plan
- Long-standing persistent AF (AF greater than one year's duration)
- Having a repeat ablation, unless the subject's index ablation procedure is also included in the registry
- In the opinion of the investigator, any known contraindication to an ablation procedure
