Multicenter retrospective evaluation of magnetic resonance imaging in pediatric and congenital heart disease patients with cardiac implantable electronic devices
Authors' conclusion
Our data provide evidence that MRIs can be performed in pediatric and CHD patients with CIEDs, including non-MRI-conditional CIEDs and epicardial and/or abandoned leads, with rare minor symptoms or CIED changes but no other complications.
Study context
- Population
- Pediatric and congenital heart disease (CHD) patients with cardiac implantable electronic devices (CIEDs) (incl. epicardial and/or abandoned leads) undergoing magnetic resonance imaging (MRI), 2007–2022, congenital cardiac centres
- Participants
- 314 participants389 MRIs14 institutions
- Outcome
- Any patient adverse event or clinically significant CIED change after MRI (capture threshold increase >0.5 V with output change, P- or R-wave amplitude decrease >50% with sensitivity change, or impedance change >50%)
