Brief Summary: The purpose of this research is to evaluate whether cryoballoon ablation vs. radiofrequency ablation guided by high-fidelity mapping (Rhythmia) is the best treatment strategy to perform repeat ablation for recurrent atrial fibrillation after previously having undergone cryoballoon ablation.
Detailed Description: The study is a randomized, prospective multicenter pilot study to assess the utility and efficacy of high-density mapping with the Rhythmia mapping system to guide PV re-isolation in subjects with recurrent AF after an initial cryoballoon PVI compared to repeat cryoballoon PVI.

After obtaining informed consent to participate in the study, subjects will undergo baseline data bcollection. Subjects will then be randomized to undergo repeat PVI with either cryoballoon ablation or repeat PVI with an IntellaNav Open-Irrigated or other approved ablation catheters for atrial fibrillation under guidance of the Rhythmia mapping system and IntellaMap Orion mapping catheter. The performance of repeat AF ablation, use either the cryoballoon or Rhythmia mapping system, mapping catheter, and ablation catheters are in accordance with standard clinical indications and practice, regardless of participation in the study.

The participants in the study will undergo a total of two follow-up visits after ablation (approximately 3 and 6 months) with a 12-lead electrocardiogram (ECG) at each visit. An assessment of rhythm will be performed with daily transmissions as well as subject-activated event recordings for symptoms with the Kardia Mobile (AliveCor, Mountain View, CA) smartphone based monitor. The Kardia Mobile System is an FDA-cleared, clinical grade mobile ECG monitor coupled with a smartphone app that is able to record a single-lead ECG and securely transmit the tracings to the study investigators via the Kardia Pro commercial (HIPPA compliant) remote monitoring service for clinicians. The transmissions will not be directly available to the treating electrophysiologists at each site.

At the 6 month visit, 2-weeks of continuous monitoring with a Zio XT event monitor (iRhythm, San Francisco, CA) will be performed according to standard clinical practice to evaluate for subclinical episodes of AF.

The goal of the pilot study is to enroll 50 subjects with 1:1 randomization across 3 sites in the Unites States and each subject will be followed for 6 months following ablation to evaluate for recurrence of AF. The estimated time to complete enrollment will be 3-4 months assuming enrollment of at each visit 4-5 subject per month at each site.
