Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • A signed written Informed Consent form
  • 18 years of age or older
  • Agrees to comply with follow-up visits and evaluation
  • Candidate for catheter ablation for the treatment of paroxysmal atrial fibrillation as per the hospital standard of care.

Exclusion Criteria:

  • Persistent or Long standing AF

Arm Description

Outcomes

Primary Outcome Measures

Procedural parameters
Ablation parameters (such as average power delivered , average tip temperature , average impedance ) Lesion locations (such as PVI, Septal line, Mitral isthmus, CTI or any other lesion location) Mapping techniques (Mapping system and catheter) RF application time ( Calculated from the total number of RF application and duration of each RF application) Ablation procedure time (Time from the first to the last RF application) Total irrigation fluid administered during ablation procedure Fluoroscopy time
AF Recurrence
Recurrence of AF through six months post last RF ablation procedure using Cool Flex catheter. A 24 hour Holter will be provided to the patients for six month follow-up visit in order to monitor AF episodes. An AF episode will be considered a recurrence only if it lasts for 30 seconds or more. AF recurrences during the blanking period (defined below) will not be reported.
Serious Adverse Events
All serious adverse events through six month follow-up
