Arm 2
Arm Type
Active Comparator
Placebo Comparator
Arm Label
ICM-guided Management
Conventional Management
Arm Description
Implantable device that provides accurate daily transmission of cardiac electrical data for arrhythmia detection.
Treating physicians/nurses will be blinded to the AF episodes data from the monitor, but will be provided information on asystole, or ventricular arrhythmia events (for safety).
Outcomes
Primary Outcome Measures
Mean amount of time spent in AF
The primary endpoint of the trial is total AF burden between 3 and 15 months after the index CA procedure (i.e. over 1-year post-blanking), as detected by an ICM which will be inserted prior to or at the time of the CA procedure in all study subjects. AF recurrence is defined as any episode of AF lasting >30 seconds. AF burden will be defined as the mean amount of time spent in AF over the pre-specified period of time (excluding short AF episodes of ≤30 seconds).
Secondary Outcome Measures
Mean Healthcare utilization
Total number of hospitalizations for any cause, ED visits, and unplanned office visits recorded at each study follow-up visit
Mean change in Functional capacity as measured by Cardiopulmonary Exercise Test (CPET)
Function capacity will be reported as peak VO2, which will be determined from CPET.
Mean change in Functional capacity as measured by ICM
The average daily count of steps derived from the inserted cardiac monitor
Mean change in Quality of life using the Atrial Fibrillation Effect on QualiTy-of-Life (AFEQT) questionnaire
The AFEQT questionnaire will be used to collect quality of life data. The questionnaire has 20 questions on a 7-point Likert scale that assess symptoms, daily activities and treatment concerns. Scores range from 20-140 with higher scores indicating worse outcomes.

5. Study Description
Brief Summary
To prospectively investigate the efficacy of an insertable cardiac monitor-guided atrial fibrillation (AF) management in reducing subsequent AF burden in patients with persistent or paroxysmal AF undergoing atrial catheter ablation (CA).
Detailed Description
In this study, 120 subjects from the University of Rochester enrolling site will be randomized (1:1) to conventional AF management vs. Abbott ICM- guided AF management following ablation for persistent AF. Subjects will be followed for 15 months including a 3 month blanking period following AF ablation. The study subject population will include subjects with paroxysmal atrial fibrillation (per 2019 HRS guidelines definition: an episode of AF that terminates spontaneously or with intervention in less than seven days) or persistent atrial fibrillation (sustained AF episode lasting more than 7 days, but less than 1 year), according to current guideline indications for persistent AF ablation and Abbott ICM implantation. The Abbott ICM incorporates a mobile app (myMerlin) that allows early detection of AF recurrence through patient-triggered remote transmissions and correlation with symptoms based on subclinical AF (SCAF) and patient-triggered remote transmissions. Future FDA-approved Abbott ICM devices using the same functionality may also be utilized in this study. This is a Phase 4 study, and we are comparing two management strategies that are currently employed in clinical practice.
