Recent developments in MRI in patients with cardiac inplanted electronic devices

By Dr NG Boyle & Dr DH Do

BACKGROUND

Over 1 million pacemakers and approximately 325,000 ICDs were implanted worldwide in 2009, and this number continues to rise annually [1]. It is likely that over 50% of patients
with a cardiac implanted electronic device (CIED) will have a clinical requirement for magnetic resonance imaging(MRI) following device implantation [2].
