Clinical Trial 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).


Clinical Trial 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. ;
