Insertable cardiac monitor management after study termination: At the conclusion of the six-month study, patients will be given the option to remove or retain the ICM. We anticipate that most patients and their primary electrophysiologists will opt to retain the device to allow for continued cardiac monitoring, which is not only useful to gauge response to AAD therapy but also frequently used to monitor AF recurrence for patients undergoing catheter ablation. If the ICM is retained, its management, including removal, will be transferred to the primary electrophysiologist. Patients wishing to have the ICM removed at the end of the study period will be scheduled for an outpatient visit in the CRC for removal by a study physician.
