Magnetic deflection forces from atrial septal defect and patent ductus arteriosus-occluding devices, stents, and coils used in pediatric-aged patients.
Magnetic deflection forces and imaging artifact were assessed for 13 pediatric interventional cardiology devices. The magnetic deflection forces incurred by these devices are small compared with physiologic forces experienced in the cardiovascular system.
