Cryoablation in Patients With Atrial Flutter

Cryoablation in Patients With Atrial Flutter

The investigators hypothesized that revealing the incidence of AF following RFA of the CTI and cryoablation PVI reduces incidence of AF following RFA of the CTI.

Inclusion Criteria:

• Age ≥ 18 years
• ECG documented paroxysmal or persistent AFL
• No prior documented history of AF
• Patient undergoing RFA of the CTI for AFL.
• No indication (other than AFL) for continued anticoagulation with warfarin.
• No existing implantable cardiac device (pacemaker, defibrillator, cardiac resynchronization therapy device)
• Availability of an analog phone line.

Exclusion Criteria:

• a history of atrial fibrillation
• Previous AF ablation procedure
• Congestive heart failure
• Left Ventricle ejection fraction less than 35%
• Unwillingness to participate
