What do national radiotherapy guidelines for patients with cardiac devices teach us?

ABSTRACT

The incidence of cardiac implantable electronic device (CIED) malfunctions caused by radiotherapy (RT) is approximately 5%. Although individual national guidelines and expert consensus documents exist, the increased use of RT to treat various cancers points out the need for a standardized document to guide risk assessment and management of CIEDs during RT. We describe potential adverse RT-related events on CIEDs as well as the proposed mechanism of dysfunction. We review the main current guidelines and recommendations, emphasizing similarities and differences.
