Chest computer tomography is safe without additional interrogation or monitoring for modern cardiac implantable electrical devices

J Cardiovasc Electrophysiol. 2022 Jun;33(6):1336-1340. doi: 10.1111/jce.15475. Epub 2022 Apr 8.


Introduction: Whether diagnostic computed tomography (CT) scans to cardiac implantable electronic devices (CIED) is safe in recent models remains unknown.

Methods: A two-centers observational study. Over 14 years, consecutive 2362 chest CT scans (1666 pacemakers [PMs], 145 cardiac resynchronization therapy PM, 316 implantable cardioverter-defibrillator, and 233 cardiac resynchronization therapy defibrillator) were interrogated and monitored upon imaging.

Results: Electromagnetic interference occurred only in a few old models: InSync 8040 (n = 14), InSync III Marquis (n = 1), and Kappa (n = 4), which resulted no adverse events.

Conclusion: CIEDs, especially recent ones, are confirmed safe on chest CT.

Keywords: CIEDs; chest CT scan; electromagnetic interference.
