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

Abstract

Whether diagnostic computed tomography(CT) scans to cardiac implantable electronic devices (CIED) is safe in recent models remains unknown. 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. Electromagnetic interference occurred only in a few old models: InSync 8040 (n = 14), InSync III Marquis (n = 1), andKappa (n = 4), which resulted no adverse events. CIEDs, especially recent ones, are confirmed safe on chest CT.
