Po-03-210 assessment of safety and time utilization of remote device interrogation in patients with conditional and non-conditional cardiac implantable electronic devices undergoing mri

MRI imaging demand has increased in the last decade for patients with a cardiac implantable electronic device (CIED). The programmed settings need to be changed prior to and reverted at the end of the scan. The conventional method for device interrogation requires the physical presence of a device representative or technician to perform this task and will soon be unsustainable due to the increase in number of CIEDs and the limitation of qualified personnel. To study the safety and efficiency of remote device interrogation technology for patients with Medtronic conditional and non-conditional devices before and after MRI. Remote device interrogation is done by establishing a secure connection between the device representative’s laptop (can be anywhere with internet connection) and the device interrogator (in MRI suite next to patient). The device representative initiates the remote session and performs device interrogation and change of device parameters, while a nurse in the MRI suite assists. Prospective analysis of patients with CIEDs who underwent MRI between December 2021 and September 2022 at Baylor Heart and Vascular Hospital in Dallas, Texas. Device representatives were given a “heads-up call” 5 minutes in advance, and then notified again when the patient is ready for interrogation. Duration of Interrogation (DOI) is the time taken from the second notification to the end of interrogation, which is performed both pre and post MRI. The sum of durations from pre and post phases were noted as Total Duration (TD). Any DOI of more than 7 minutes in either phase was classified as a delay in interrogation and delay reasons were collected. Data was collected from 189 patients, remote group (REM) had 90 patients and face to face group (F2F) had 99 patients. All devices interrogated remotely were Medtronic as they were the only vendor that had the technology which maintained complete control of interrogation by device representative. Average TD for REM were less than F2F (figure 1). Workflow delays in either pre or post-MRI interrogations were less in REM (42%) vs F2F (53%), p-value 0.051 (figure 2). No device malfunction, lead damage, patient morbidity or mortality occurred during the study. Remote interrogation of Medtronic conditional and non-conditional CIEDs for patients undergoing MRI is safe and can improve time efficiency while minimizing the need for onsite device representatives.Tabled 1Figure 1RemoteFace to FaceNumber of Patients9099DeviceAll Medtronic58 Medtronic, 24 Abbott,17 Boston scientificNon-conditional39/90 (43%)38/99 (38%)Average TD12 minutes and 30 seconds15 minutes and 13 secondsMinimum TD3 minutes4 minutesQ1 (25th%)8 minutes9 minutesQ2 (50th%, Median)10 minutes11 minutesQ3 (75th%)14 minutes18 minutesInter-quartile Range6 minutes9 minutesTD ≤ 10 minutes (p-value 0.03)44/90 (49%)33/39 (33%)TD ≤ 15 minutes (p-value 0.01)68/90 (76%)58/99 (58%)TD = Total Duration Open table in a new tab
