Outcomes after magnetic resonance imaging in patients with pacemakers and defibrillators and abandoned leads
1 Introduction
Up to 75% of patients with a cardiac implantable electronic device (CIED), encompassing pacemakers and implantable cardioverter defibrillators, will be referred for magnetic resonance imaging (MRI) [ ]. Current protocols for patients with both MRI conditional and non-MRI conditional CIEDs exclude patients with leads disconnected from their generator, termed ‘abandoned’ leads, due to safety concerns [ ]. The outcomes of patients with CIEDs and abandoned leads undergoing MRI are uncertain.
