Over the last twenty years there has been a rapid expansion in the vast array of implantable cardiac devices utilized in pediatric patients. Imaging plays a key role in the management of patients with these devices. It is important for the pediatric radiologist to recognize the specific type of cardiac device visualized on radiographic images in order to make an accurate assessment of the appropriate position and any potential complications. With new cardiac devices entering the market it can be very perplexing and daunting for the radiologist to stay familiar with them all.

We will seek to review old and new pediatric cardiac devices currently used at our institution and their radiographic appearance.

These devices will be divided into categories of pacing devices, prosthetic heart valves, stents, closure devices, ventricular assist devices, extracorporeal membrane oxygenation systems (ECMO), and external monitoring devices.

Pacing devices: a) Epicardial and transvenous pacing systems b) Leadless pacemakers
Prosthetic heart valves: a) Surgically implanted valves b) Transcatheter valves
Cardiac stents
Closure devices: a) Patent ductus arteriosus closure device, b) Atrial septal defect closure device c) Vascular plugs and coils
Ventricular assist devices: a) Left ventricular assist device, b) Right ventricular assist device, c) Bi-ventricular assist device
Extracorporeal membrane oxygenation (ECMO) cannulas: a) Venous-arterial ECMO, b) Venous-venous ECMO
External monitoring devices: a) Holter monitor, b) Loop recorder Read More

After reviewing this educational exhibit, radiologists and trainees will have up-to-date knowledge about magnetic resonance imaging (MRI) safety in children with implanted medical devices. The following will be presented: 1) Basic MRI physics relating to safety risks in the presence of implanted (passive and active) medical devices, 2) MR Safety screening challenges specific to children, and 3) Review of newly developed or updated medical devices that present challenging pediatric MRI safety scenarios.

MRI is the imaging modality of choice for assessing many pediatric conditions, providing excellent anatomic and pathologic detail without the use of ionizing radiation. However, there are significant potential hazards in the MR environment related to the static magnetic field and the spatial and time varying gradient fields, as well as the impact of radiofrequency pulses. These concerns may be further complicated/exacerbated by the presence of implanted medical devices.

This educational exhibit will focus on reducing risk for children with implanted medical devices in the MR environment. Such devices may be subject to projectile/torsion forces, induced currents, and heating risks. Barriers to effective screening include limited MRI safety information for new passive and active implanted medical devices, incomplete documentation and patient/family education, and limited referring clinician awareness of potential safety risks. The use of sedation/anesthesia in pediatric patients reduces the ability to detect discomfort during MR imaging. Read More

The purpose is for participants to become familiar with devices that are commonly and uncommonly used in the pediatric population. They will learn the proper location and configuration of these devices, which will be useful throughout their professional career. Being able to recognize subtle abnormalities that can occur with these devices is important for radiologists, and being aware of basic information of these devices can help other physicians when they become exposed to them in their career.
