Brief Summary:
This study is being done to find out if patients taking Anti Arrhythmia Drugs (AADs) after cryoballoon ablation for atrial fibrillation, compared to patients who do not take Anti- Arrhythmic Drugs after an ablation affect Atrial Fibrillation from coming back. The study will also look at the side effects of the AADs.

Condition or disease Intervention/treatment Phase
Atrial Fibrillation Other: No AAD post Ablation. Not Applicable

Detailed Description:
Pulmonary vein isolation (PVI) is a cornerstone ablation strategy used in the management of paroxysmal atrial fibrillation (PAF), and it is a class IA indication for anti-arrhythmic drug (AAD) refractory symptomatic PAF. However, the consensus statements are vague about the utility of AAD management during the 90-day blanking window post-PVI. Moreover, there is no specific guidance to cryoballoon users on the usage of AADs during the 90-day blanking period that exists anywhere in the published literature. Simply, these studies have not been conducted with the cryoballoon procedure.

Arm Intervention/treatment
Active Comparator: Arm 1- No AAD post Ablation
Subjects will not resume their Anti Arrhythmic Drugs after cryoballoon-ablation for paroxysmal atrial fibrillation.
Other: No AAD post Ablation.
Subjects will not resume their pre-ablation anti-arrhythmic medications during the 90 following cryo ablation for Atrial Fibrillation
Other Name: No AAD

No Intervention: Arm 2-Resume AAD post Ablation
Subjects will resume their pre-ablation Anti Arrhythmic Drugs after cryoballoon-ablation for paroxysmal atrial fibrillation, during the 90 day blanking period following the ablation.

Primary Outcome Measures :
  1. Compare recurrence, recurrence rate, burden of atrial fibrillation post ablation between the two groups. [ Time Frame: 12 months ]

    Rhythm status through implantable loop recorder (or pacemaker with functioning atrial lead) at 3 month, 6 month, 12 month compared between two treatment groups, including:

    A) AF burden (Average amount of time in AF per day) B) AF recurrence rate (Frequency of AF, occurrences per day) C) Time to AF recurrence

  2. Symptom Assessments [ Time Frame: 12 months ]
    Symptom assessments by clinical follow up and phone calls, including symptom severity score using the Severity of Atrial Fibrillation Scale between the two groups.

  3. Adverse Events Assessments [ Time Frame: 12 months ]
    Ongoing assessment of adverse events in both arms of the study, including AADs side effects in 90-day blanking period.

Secondary Outcome Measures :
  1. The cost of AADs during the 90-day blanking period. [ Time Frame: 12 months ]
    The cost of AADs during the 90-day blanking period.

  2. Assess the rate of hospitalizations, emergency room visits, and unscheduled cardiology visits for the treatment of AF between the two groups [ Time Frame: 12 months ]
    A) Event during the 90-day blanking period will be assessed for AAD related and unrelated adverse events that caused the cardiac related visit

  3. The differential usage of anticoagulation therapy between two arms. [ Time Frame: 12 months ]
    The differential usage of anticoagulation therapy between two arms.
