Synopsis

Infants and children with congenital heart disease may require cardiovascular implantable electronic devices (CIEDs), which typically precludes future evaluation by MRI due to risks associated with RF heating of implants. Here we demonstrate that a novel concept based on patient-adjustable rotating RF coil technology that was originally developed to reduce RF heating of brain implants can be adopted in pediatric patients with CIEDs to substantially reduce RF heating. Our simulations in a cohort of children with both epicardial and endocardial devices showed an 87% reduction in average SAR compared to conventional body coils.
