Abstract

Abstract: 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.
