NCT03811795

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.

Outcome Measures

Primary Outcomes (1)

  • PrimaryCryoballoon vs. Rhythmia Guided Ablation for Recurrent AFib

    The freedom from atrial fibrillation at 6 months is the primary endpoint. The presence or absence of atrial fibrillation will be assessed during the study period.

    Six months

Study Arms (2)

Arm 1-Repeat Cryoballoon Ablation

OTHER

Subjects will be randomized to repeat cryoballoon ablation.

Other: ECG monitoring with a Kardia Mobile monitor

Arm 2-Radiofrequency Ablation

OTHER

Participants will have radiofrequency ablation guided by high-fidelity mapping (Rhythmia) following an initial cryoballoon ablation.

Other: ECG monitoring with a Kardia Mobile monitor

Interventions

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 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 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.

Eligibility Criteria

Age18 Years - 100 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Individuals with paroxysmal or persistent AF undergoing repeat AF ablation as per recent HRS guidelines and standard practice;
  • Individuals in whom the initial ablation approach was cryoballoon PVI at the enrolling institution more than 3 month or more prior to the anticipated repeat ablation;
  • Age ≥ 18 years.

You may not qualify if:

  • Individuals with recurrent AF who previously underwent RF-based PVI;
  • Individuals with known contraindications to ablation including permanent atrial fibrillation or intolerance of anticoagulation;
  • Individuals unable or not willing to complete follow-up visits and examination for the duration of the study;
  • Individuals without access to smartphone or tablet compatible with the monitoring system;
  • Prior valve surgery or surgical AF ablation;
  • Individuals with mental or physical limitations precluding informed consent;
  • Individuals currently enrolled in another investigational study or registry;
  • Women of childbearing potential who are, or plan to become, pregnant during the time of the study.

Intervention Model

Model Details: 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 collection. 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.
