Publication How I Do It: Evaluating Cardiac Implantable Devices and Noncardiac Mimics on Chest Radiographs(2025) Silva, Claudio; Christensen, JaredCardiac implantable electronic devices (CIEDs), including pacemakers and defibrillators, are increasingly used to manage various cardiac conditions. This article reviews the radiographic appearance, typical components, and placement of CIEDs, including newer technologies like leadless pacemakers and MRI-conditional devices. The article also highlights the imaging findings of common complications such as lead dislodgement, fracture, and perforation, emphasizing the role of imaging in early detection and intervention. Additionally, the radiographic identification of other cardiac and noncardiac devices with similar-appearing imaging features is addressed. Other cardiac devices covered in this article include those for cardiac monitoring, ventricular assistance, and cardiac repair. Noncardiac mimics include deep brain, vagal nerve, and phrenic nerve stimulators as well as breast implant radiofrequency markers. Accurately identifying these devices and their positioning on chest radiographs facilitates the early detection of complications and directs appropriate patient care.
